IMPORTANT SAFETY INSTRUCTIONS
• If there is a fire in the oven during baking, smother the fire by closing
the oven door and turning the oven off or by using a multi-purpose dry
chemical or foam-type fire extinguisher.
• Do not use any type of foil or liner to cover the oven bottom or
anywhere in the oven, except as described in this manual. Oven liners
can trap heat or melt, resulting in damage to the product and risk of
shock, smoke or fire.
• Use Only Dry Potholders – Moist or damp potholders on hot surfaces
may result in burns from steam. Do not let potholder touch hot heating
elements. Do not use a towel or other bulky cloth.
• DO NOT TOUCH SURFACE UNITS OR AREAS NEAR UNITS – Surface units
may be hot even though they are dark in color. Areas near surface units
may become hot enough to cause burns. During and after use, do not
touch, or let clothing or other flammable materials contact surface units
or areas near units until they have had sufficient time to cool. Among
these areas are the coil elements, the cooktop, and surfaces facing the
cooktop.
• DO NOT TOUCH HEATING ELEMENTS OR INTERIOR SURFACES OF OVEN
– Heating elements may be hot even though they are dark in color.
Interior surfaces of an oven become hot enough to cause burns. During
and after use, do not touch, or let clothing or other flammable materials
contact heating elements or interior surfaces of oven until they have
had sufficient time to cool. Other surfaces of the appliance may
become hot enough to cause burns – among these surfaces are oven
vent openings and surfaces near these openings, oven doors, and
windows of oven doors.
• Do Not Cook on Broken Cooktop – If cooktop should break, cleaning
solutions and spillovers may penetrate the broken cooktop and create a
risk of electric shock. Contact a qualified technician immediately.
• Avoid scratching or impacting glass doors, cooktops, or control panels.
The cooktop can be scratched with items such as knives, sharp
instruments, rings or other jewelry, and rivets on clothing. Doing so may
lead to glass breakage.
• Never Leave Surface Units Unattended at High Heat Settings – Boilover
causes smoking and greasy spillovers that may ignite.
READ AND SAVE THESE INSTRUCTIONS
10
IMPORTANT SAFETY INSTRUCTIONS
• Do Not Heat Unopened Food Containers – Build-up of pressure may
cause container to burst and result in injury.
• Wear Proper Apparel – Loose-fitting or hanging garments should never
be worn while using the appliance.
• Use Proper Pan Size – This appliance is equipped with one or more
surface units of different size. Select utensils having flat bottoms large
enough to cover the surface unit heating element. The use of
undersized utensils will expose a portion of the heating element to
direct contact and may result in ignition of clothing. Proper relationship
of utensil to heating element will also improve efficiency.
• Glazed Cooking Utensils – Only certain types of glass, glass/ceramic,
ceramic, earthenware, or other glazed utensils are suitable for range-
top service without breaking due to the sudden change in temperature.
• Utensil Handles Should Be Turned Inward and Not Extend Over
Adjacent Surface Units – To reduce the risk of burns, ignition of
flammable materials, and spillage due to unintentional contact with the
utensil, the handle of a utensil should be positioned so that it is turned
inward, and does not extend over adjacent surface units.
• If power is lost to an electric cooktop with knob surface unit controls
while a surface unit is ON, the surface unit will turn back on as soon as
power is restored. In the event of power loss, failure to turn all surface
unit knobs to the OFF position may result in ignition of items on or near
the cooktop, leading to serious injury or death.
• Do not place or store items that can melt or catch fire on the glass
cooktop, even when it is not being used. If the cooktop is inadvertently
turned on, they may ignite. Heat from the cooktop or oven vent after it
is turned off may cause them to ignite also.
• Use Care When Opening Door – Let hot air or steam escape before
removing or replacing food.
• Never broil with door open. Open-door broiling is not permitted due to
overheating of control knobs.
• Care must be taken to prevent aluminum foil and meat probes from
contacting heating elements.
READ AND SAVE THESE INSTRUCTIONS
11
IMPORTANT SAFETY INSTRUCTIONS
• Placement of Oven Racks – Always place oven racks in desired location
while oven is cool. If rack must be moved while oven is hot, do not let
potholder contact hot heating element in oven.
• Injuries may result from misuse of appliance doors or drawers such as
stepping, leaning, or sitting on the doors or drawers.
• Storage in or on Appliance – Flammable materials should not be stored
in an oven or near surface units.
• This appliance is not intended for storage.

materials, gasoline, and other flammable vapors and liquids.
• Do not let cooking grease or other flammable materials accumulate in
or near the range. Grease in the oven or on the cooktop may ignite.
• Keep Oven Vent Ducts Unobstructed.
• Clean Cooktop With Caution – If a wet sponge or cloth is used to wipe
spills on a hot cooking area, be careful to avoid steam burn. Some
cleaners can produce noxious fumes if applied to a hot surface.
• Use care when touching the cooktop. The glass surface of the cooktop
will retain heat after the controls have been turned off.
• Do Not Soak Removable Heating Elements – Heating elements should
never be immersed in water.
• Do Not Clean Door Gasket – The door gasket is essential for a good
seal. Care should be taken not to rub, damage, or move the gasket.
• Do Not Use Oven Cleaners – No commercial oven cleaner or oven liner
protective coating of any kind should be used in or around any part of
the oven.
• Clean Only Parts Listed in Manual.
• Do not use replacement parts that have not been recommended by the
manufacturer (e.g. parts made at home using a 3D printer).

COOKTOP
BEFORE USING THE COOKTOP
Read all instructions before using.
WARNING
• Do not cook on a broken cooktop. If the cooktop is broken, cleaning
solutions and spillovers may penetrate the broken cooktop and create a
risk of electric shock. Contact a qualified technician immediately.
• Do not place or store items that can melt or catch fire on the glass
cooktop, even when it is not being used.
• Never leave surface units unattended at high heat settings. Boilovers
cause smoking and greasy spills that may catch on fire.
• Keep flammable items away from the cooktop.
• Turn off all controls when done cooking.
• Turn cookware handles inward and not extend over adjacent surface
units to reduce the risk of burns, ignition of flammable materials, and
spillage due to unintentional contact with the cookware.
• Always place the pan in the center of the surface unit you are cooking
on. Proper contact of cookware to heating element also will improve
efficiency.
• Clean cooktop with caution. If a wet sponge or cloth is used to wipe
spills on a hot cooking area, be careful to avoid steam burn. Some
cleaners can produce noxious fumes if applied to a hot surface.
27
CAUTION
• Never cook directly on the glass. Always use cookware.
• Do not use the glass cooktop surface as a cutting board.
• Do not slide metal or glass across the cooktop surface. Cookware with
rough or uneven bottoms can mark or scratch the cooktop surface.
• Do not place sealed containers on the cooktop.
• Do not place aluminum foil or plastic items such as salt and pepper
shakers, spoon holders, or plastic wrappings or any other material on
the range when it is in use.
• Do not turn surface units on before placing cookware.
• Always turn the surface units off before removing cookware.
• The surface element may appear to have cooled after it has been
turned off. The element may still be hot and touching the element
before it has cooled sufficiently can cause burns.
• Only certain types of glass, glass-ceramic, ceramic, earthenware, or
other glazed cookware are suitable for range-top service without
breaking due to the sudden change in temperature.
• Choose proper heating element size. For smaller pots and pans, use the
smaller heating elements. For larger pots and pans, use the larger
heating elements. Select pans that have flat bottoms large enough to
cover the heating elements. Using undersized pans exposes a portion of
the heating element to direct contact and may result in clothing
burning.
• Immediately clean spills on the cooking area to prevent a tough
cleaning chore later.
• Do not use a steel-wool pad or scrub pad or abrasive cleaning pads.
They can scratch the surface.
COOKING AREAS
The cooking areas on your range are identified by permanent circles on the
glass cooktop surface.
When a control is turned on, a glow can be seen through the glass cooktop
surface.
For the most efficient cooking, fit the pan size to the element size. Pans should
not extend more than 1/2" to 1" (1.3 cm to 2.5 cm) beyond the cooking area.

USING THE PROPER COOKWARE
The size and type of cookware will influence the settings needed for the best
cooking results. Cookware should have flat bottoms that make good contact
with the entire surface heating element, and should not extend more than 1/2"
to 1" (1.3 cm to 2.5 cm) beyond the cooking area for the most efficient cooking.
Using the correct cookware can prevent many problems, such as uneven
cooking or extended cooking times.
Cookware Recommendations
• Flat bottom and straight sides
• Heavy-gauge pans
• Pan sizes that match the amount of food to be prepared and the size of
the surface element
• Weight of handle does not tilt pan.
• Pan is well balanced
• Tight-fitting lids
• Flat bottom woks
Note:
• Do not use woks that have support rings. This type of wok will not heat
on glass surface elements.
• Do not use foil or foil-type containers. Foil may melt onto the glass. Do
not use the cooktop if metal has melted on it.
32
Choosing Cookware
The cookware material determines how evenly and quickly heat is transferred
from the surface element to the pan bottom.
Recommended
• Aluminum - Excellent heat conductor. Some types of food will cause it to
darken (anodized aluminum cookware resists staining and pitting). If
aluminum pans slide across the ceramic cooktop, they may leave metal
marks which will resemble scratches. Remove these marks immediately.
Because of its low melting point, thin weight aluminum should not be
used.
• Copper - Excellent heat conductor but discolors easily. May leave metal
marks on glass-ceramic (see Aluminum above). Do not let these pots boil
dry. Overheated metal can bond to glass cooktops. An overheated
copper bottom pot will leave a residue that will permanently stain the
cooktop if not removed immediately.
• Stainless Steel - Slow heat conductor with uneven cooking results. Is
durable, easy to clean and resists staining.
• Enamel (painted) on Cast Iron - Bottom of pan must be smooth coated
and smooth.
Not Recommended
• Enamel (painted) on Steel - Heating empty pans can cause permanent
damage to cooktop glass. The enamel can melt and bond to the ceramic
cooktop.
• Cast Iron - A poor heat conductor, slow to absorb heat but retains heat
very well. Will scratch the glass surface. Not recommended unless
designed specifically for use on ceramic cooktops.
• Glass-ceramic - Slow heat conductor. Poor performance, and will scratch
the glass surface.
• Stoneware - Poor performance, and may scratch the glass surface.
33
OVEN
BEFORE USING THE OVEN
Read the instructions for each feature and cooking mode in this manual
carefully before using the oven.
CAUTION
• Do not use any type of foil or oven liner to cover the oven bottom. These
items can trap heat or melt, resulting in damage to the product and risk
of shock, smoke or fire. Damage from improper use of these items is not
covered by the product warranty.
• Foil may be used to catch spills by placing a sheet on a lower rack,
several inches below the food. Do not use more foil than necessary and
never entirely cover an oven rack with aluminum foil. Keep foil at least
1-1/2" (3.8 cm) from oven walls to prevent poor heat circulation.
• Do not cover the slotted grid of the 2-piece broiler pan with aluminum
foil. This will catch the grease and could cause fire.
• Do not use plastic wrap or wax paper in the oven.
• Do not place food, water, ice, or any dish or tray directly on the oven
floor, as this will irreversibly damage the enamel surface.
• Do not block, touch or place items around the oven vent during cooking.
Your oven is vented through ducts at the center above the rear cooktop.
Do not block the oven vent when cooking to allow for proper air flow.
• The oven and broiler cannot be used during a power outage. If the oven
is in use when a power failure occurs, the oven heating element shuts
off and cannot be used until power is restored. Once power is restored,
you will need to reset the oven (or Broil mode).
• As the oven heats up, the heated air in the oven may cause
condensation to appear on the oven door glass. These water drops are
harmless and will evaporate as the oven continues to heat up.
34
CAUTION
Food Poisoning Hazard
• Do not let food sit in oven more than one hour before or after cooking.
• Foods that can easily spoil such as milk, eggs, fish, meat or poultry,
should be chilled in the refrigerator first. Even when chilled, they should
not stand in the oven for more than 1 hour before cooking begins, and
should be removed promptly when finished cooking. Consuming spoiled
food can result in food poisoning or sickness.
BEFORE USING THE OVEN FOR THE FIRST TIME
Start the oven in Bake mode at the highest available temperature setting.
Allow oven to run for 1 hour to remove any dust or impurities. There will be a
distinctive odor - this is normal. Ensure your kitchen is well ventilated during
this conditioning period.
OVEN VENT
Areas near the vent may become hot during operation and may cause burns.
Avoid placing plastics near the vent as heat may distort or melt the plastic.
Do not block the vents (air openings) of the range. They provide the air inlet
and outlet that are necessary for the range to keep cool and operate properly
with correct combustion.
It is normal for steam to be visible when cooking foods with high moisture
content.
Oven vent
35
OVEN DOOR
Oven heating elements and, if in operation, convection fan will temporarily
shut off any time door is opened, and will resume when door is closed within 3
minutes.
Note:
To avoid oven door glass breakage:
USING OVEN RACKS
The racks have a turned-up back edge that prevents them from being pulled
out of the oven cavity.
CAUTION
• Do not leave the door open any longer than necessary. If the door is left
open too long for over 3 minutes, the cooking mode will be
automatically cancelled.
• Do not close the oven door if the racks are not fully inserted into the oven
cavity or if bakeware extends past the front edge of an oven rack.
• Do not set objects on the glass surface of the oven door.
• Do not hit glass surfaces with bakeware or other objects.
• Do not wipe down glass surfaces until the oven has completely cooled.
• Replace oven racks before turning the oven on to prevent burns.
• Do not cover the racks with aluminum foil, or any other material, or
place anything on the bottom of the oven. Doing so will result in poor
baking and may damage the oven bottom.
• Only arrange oven racks when the oven is cool.

Removing Racks
Replacing Racks
1. Pull the rack straight out until it
stops.
2. Lift up the front of the rack and
pull it out.
1. Place the end of the rack on the
support.
2. Tilt the front end up and push the
rack in.
Broiling performs best with the food close to the broil heating element -
typically rack position #5 or #6.
Rack Positions
For best cooking results, adjust rack so
food is placed at the center of the
oven. For most foods this will be rack
position #3 or #4. For larger foods like
roasts and turkey, move the rack
position down to #2 or #1 to keep the
food centered in the oven.
When using multiple racks
simultaneously, try to space the food
out around the oven center (rack
positions #3 and #5 or #2 and #4 for
two racks).
37
PREHEATING
Preheating is generally desirable, although not absolutely necessary in all
circumstances.
• For oven modes that utilizes preheat, the control will automatically enter
preheat mode and show "PRE" after Start is pressed to turn on the oven.
– Once the set temperature is reached, an indicator tone will sound for
a few seconds to alert the user that preheat is complete.
• Broil and Warm modes do not utilizes preheat, the control will show Hi or
Lo for Broil and 175°F (79°C) for Warm after Start is pressed to turn on the
oven.
Note:
• It is normal for the convection fan to operate during preheating of
various baking modes.
Some foods are more robust and may have acceptable results without
preheating. These foods include large pieces of meat (whole roasts, hams, or
poultry) where the total cooking time is much longer than the time required to
preheat. These foods also include frozen potato products and frozen
processed dinners that, by their nature and design, are more robust to baking
variations. More delicate foods, such breads (including cakes, cookies,
pastries, and pizzas), desserts, soufflés, etc. will likely not have acceptable
results without proper preheating.
38
MINIMUM & MAXIMUM DEFAULT SETTINGS
The various baking modes (Bake, Conv Bake, and Air Fry) have a 10-hour time
limit, after which the control will automatically end the baking mode. Broil
and Keep Warm modes have a 3-hour time limit. If desired, these modes can
be restarted after the time limit expires.

oven.
Note:
• Baking time and temperature will vary depending on the
characteristics, size, and shape of the baking pan used.
• Check for food doneness at the minimum recipe time.
• Use metal bakeware (with or without a nonstick finish), heatproof glass-
ceramic, ceramic or other bakeware recommended for oven use.
• Dark metal pans or nonstick coatings will cook food faster with more
browning. Insulated bakeware will slightly lengthen the cooking time for
most foods.
CONVECTION BAKE
The Convection Bake mode uses heat from the lower heating element and air
movement from the convection fan to enhance cooking efficiency and
evenness across multiple racks. Always preheat the oven first. Baking times
may be slightly longer for multiple racks than what would be expected for a
single rack.
Setting the Convection Bake Mode
For example, to Convection Bake at 375°F.

placing food. If the door is left open too long for over 3 minutes, the
cooking mode will be automatically cancelled.
8. Press Cancel/Off when cooking is finished, and remove the food from the
oven.
42
Note:
• The oven fan runs while convection baking.
• Use Convection Bake for faster and more even multiple-rack cooking of
pastries, cookies, muffins, biscuits, and breads of all kinds.
• Place the oven racks in positions suggested in the "Tips and Techniques"
section.
• Bake cookies and biscuits on pans with no sides or very low sides to
allow heated air to circulate around the food. Food baked on pans with
a dark finish will cook faster.
AIR FRY
The Air Fry mode uses heat from the upper and lower heating elements and
hot air movement from the convection fan to circulate hot air inside the oven.
This mode is specially designed for oil-free frying, and to produce foods with a
crispier exterior than traditional oven cooking. The Air Fry mode is intended
for single rack cooking only. Always preheat the oven first and place food
centrally near the middle racks.
Setting the Air Fry Mode
For example, to Air Fry at 400°F.
1. Adjust oven rack levels as needed.
2. Press Air Fry to select Air Fry mode.
3. Press/hold + or - to set the air fry temperature to 400°F.

placing food. If the door is left open too long for over 3 minutes, the
cooking mode will be automatically cancelled.
8. Press Cancel/Off when cooking is finished, and remove the food from the
oven.
Note:
• The oven fan runs while air frying.
• Use the air fry tray provided or pans with low sides or no sides for better
air flow over foods.
BROIL
The Broil mode uses intense heat from the upper heating element to sear
foods. This mode works best for tender cuts of meat, fish, and thinly cut
vegetables, and is ideal for toasting, melting cheese, browning and searing
surface. Food should be placed near the upper racks, and should not be
cooked for too long on each side of the food.
44
Setting the Broil Mode
1. Adjust oven rack levels as needed.
2. Press Broil once to select Hi Broil or twice to select Lo Broil.
3. Press Start.
The oven starts to preheat, and HI or LO remains in the display. Keep the
oven door closed.
Note:
• If the oven door is opened at the time Start is pressed, the oven will
turn on when the oven door is closed.
4. Place the food in the oven after preheating for 5 - 10 minutes.

• Do not leave the door open any longer than necessary when
placing food. If the door is left open too long for over 3 minutes, the
cooking mode will be automatically cancelled.
5. Press Cancel/Off when cooking is finished, and remove the food from the
oven.
Note:
• The oven of this range is designed for closed-door broiling. Opening the
door turns off the broil heating element during broiling. If the door is
not closed, the Broil mode will ultimately cancel itself.
• The broil heating element is very powerful. Follow recipe directions and
monitor food closely to reduce risk of burning food.
• Always use a broiler pan and grid for excess fat and grease drainage.
This will help to reduce splatter, smoke, and flare-ups. Do not use a
broiler pan without a grid. Oil can cause a grease fire.
• Do not cover the grid and broiler pan with aluminum foil. Doing so will
cause a fire.
45
KEEP WARM
The Keep Warm mode uses heat from the lower heating element to maintain
oven temperature at around 175°F (79°C). It will keep cooked food warm for
serving up to 3 hours after cooking has finished. Cover foods that need to
remain moist and do not cover foods that should be crisp. Preheating is not
required.
Setting the Keep Warm Mode
1. Adjust oven rack levels as needed.
2. Place the hot food in the oven.
3. Press Keep Warm to select Keep Warm mode.
4. Press Start.
The oven starts to preheat, and 175F (79°C) remains in the display. Keep
the oven door closed.

food down.
• Avoid opening the oven door more than necessary during use. If the
door is left open too long for over 3 minutes, the cooking mode will be
automatically cancelled.
46
TIPS AND TECHNIQUES
Bake
Baking is cooking with heated air. The lower element in the oven is used to
heat the air but no fan is used to circulate the heat.
Follow the recipe or convenience food directions for baking temperature, time
and rack position. Baking time will vary with the temperature of ingredients
and the size, shape and finish of the baking utensil.
• For best results, bake food on a single rack with at least 1" - 1½" (2.5 - 3
cm) space between utensils and oven walls.
• Use one rack when selecting the bake mode.
• Check for doneness at the minimum time.
• Use metal bakeware (with or without a non-stick finish), heatproof glass,
glass-ceramic, pottery or other utensils suitable for the oven.
• When using heatproof glass, reduce temperature by 25°F (15°C) from
recommended temperature.
• Use baking sheets with or without sides or jelly roll pans.
• Dark metal pans or nonstick coatings will cook faster with more browning.
Insulated bakeware will slightly lengthen the cooking time for most foods.
• Do not use aluminum foil or disposable aluminum trays to line any part of
the oven. Foil is an excellent heat insulator and heat will be trapped
beneath it. This will alter the cooking performance and can damage the
finish of the oven.
• Avoid using the opened door as a shelf to place pans.
• See Troubleshooting for tips on solving Oven Problems.
47
Convection Bake
Convection Bake uses heat from the lower heating element and air movement
from the convection fan to enhance cooking efficiency and evenness across
multiple racks. Reduce recipe baking temperatures by 25°F (15°C).
• For best results, foods should be cooked uncovered, in low-sided pans to
take advantage of the forced air circulation. Use shiny aluminum pans for
best results unless otherwise specified.
• Heatproof glass or ceramic can be used. Reduce temperature by another
25°F (15°C) when using heatproof glass dishes for a total reduction of
50°F (30°C).
• Dark metal pans may be used. Note that food may brown faster when
using dark metal bake ware.
• The number of racks used is determined by the height of the food to be
cooked.
• Baked items, for the most part, cook extremely well in convection. Don’t
try to convert recipes such as custards, quiches, pumpkin pie, or
cheesecakes, which do not benefit from the convection-heating process.
Use the regular Bake mode for these foods.
• Multiple rack cooking for oven meals is
done on rack positions 1, 2, 3, 4, 5, and
6. All six racks can be used for cookies,
biscuits and appetizers.
– 2 Rack baking: Use positions 3 and
5 or 2 and 4.
– 3 rack baking: Use positions 2, 3,
and 4 or 1, 3, and 5 or 2, 4, and 6.
– When baking four cake layers at
the same time, stagger pans so
that one pan is not directly above
another. For best results, place
cakes on front of upper rack and
back of lower rack (See graphic at
right). Allow 1" - 1 ½" (2.5 - 3cm) air
space around pans.
• Converting your own recipe can be easy. Choose a recipe that will work
well in convection.
• Reduce the temperature and cooking time if necessary. It may take some
trial and error to achieve a perfect result. Keep track of your technique for
the next time you want to prepare the recipe using convection.
• See Troubleshooting for tips to Solving Baking and Roasting Problems.

Foods recommended for convection bake mode:
Appetizers, Biscuits, Cakes, Casseroles, Coffee Beans, Cookies (2 to 4 racks),
Cream Puffs, Popovers, Yeast Breads, One-Dish Entrées, Oven Meals (rack
positions 3 and 4), and Air Leavened Foods (Soufflés, Meringue, Meringue-
Topped Desserts, Angel Food Cakes, Chiffon Cakes).
Air Fry
The Air Fry mode uses heat from the upper and lower heating elements and
air movement from the fans to circulate hot air inside the oven and to
produce foods with a crispier exterior than traditional oven cooking.
• For best results, use the provided air fry tray and position oven rack so
that food is placed centrally near the middle racks.
• If you don't have the air fry tray, place food on a wire rack inside a foil-
lined broiler pan or on a dark baking pan with low sides or no sides fo r
better air flow over foods.
• Spread the food out evenly in a single layer. Check food often and shak e
it or turn it over for crisper results.
• If desired, spray the baking tray or air fry tray with a pan spray. Use an oi l
that can be heated to a high temperature before smoking, such as
avocado, grapeseed, peanut or sunflower oil.
• Place a foil-lined baking tray on the bottom rack to catch the oil fallin g
from the food. For high fat foods like chicken wings, add a few sheets o f
parchment paper to absorb the fat.
• Foods high in fat will smoke when using the Air Fry mode. Turn on your
exhaust hood at a high fan setting or open a window to make sure t he
kitchen is well-ventilated.
• Prepared frozen foods may cook faster with the Air Fry mode than state d
on the package. Reduce the cooking time by about 20 percent, chec k
food early, and adjust cooking time as needed.
Broil
The Broil mode uses intense heat from the upper heating element to sear
foods. The size, weight, thickness, starting temperature, and your preference
of doneness will affect broiling times.
• For best results when broiling, use a pan designed for broiling.
• Preheat the oven for about 5 minutes before placing food in the oven.
49
RANGE CARE AND MAINTENANCE
MANUAL CLEANING
IMPORTANT: Before cleaning, make sure all controls are off and the oven and
cooktop are cool. Always follow label instructions on cleaning products. Soap,
water and a soft cloth or sponge are suggested first unless otherwise noted.
Do not use abrasive cleaning products.
Note:
• Do not clean the oven door gasket. The material of the gasket cannot
withstand abrasion. It is essential for the gasket to remain intact. If you
notice it becoming worn or frayed, replace it.
• Re-engage the anti-tip bracket if range is moved.
GLASS-CERAMIC COOKTOP
• Before using the cooktop for the first time, clean it with a ceramic cooktop
cleaner. This helps protect the top and makes cleanup easier.
• Regular use of ceramic cooktop cleaner will help keep the cooktop
looking new.
• If any sugar or food containing sugar spills, or plastic or foil melts on the
cooktop, remove the material IMMEDIATELY with a metal razor scraper
while the cooking surface is still hot to avoid the risk of damage to the
glass-ceramic surface. When used correctly, the scraper will not damage
the cooktop surface.
• For your safety, please use an oven mitt or pot holder while scraping the
hot cooking surface.
• If water or food containing water spills, remove the spill IMMEDIATELY
with a dry paper towel.
• Do not use scrub pads or abrasive cleaning pads. They may damage your
cooktop surface.
50
Cleaning Method:
• Use ceramic cooktop cleaner on the glass cooktop. Other creams may not
be as effective or may scratch, damage or stain the cooktop surface.
• Use a paper towel or non-scratch cleaning pad to clean the entire
cooktop surface.
• Rinse with clear water and use a dry cloth or paper towel to remove all
cleaning residue.
Note:
• Any damage or failure of the product resulting from the items
below may not be covered under the Limited Warranty.
- Sugary spillovers (such as preserves, ketchup, tomato sauce,
jellies, fudge, candy, syrups, or chocolate) or melted plastics
can cause pitting on the surface of your cooktop.
- If food or water containing calcium (such as baking powder,
wine, milk, spinach, or broccoli) is spilled on the cooktop, it can
permanently stain or discolor the surface.
BURNED-ON RESIDUE
• Allow the cooktop to cool.
• For additional protection, after all residue has been removed, polish the
entire surface with ceramic cooktop cleaner and a paper towel.
Cleaning Methods:
• Spread a few drops of ceramic cooktop cleaner on the entire burned
residue area. Using a non-scratch cleaning pad for ceramic cooktops, rub
the residue area, applying pressure as needed. Leave the cleaner on for
10 minutes before rinsing it off.
• Rinse with clear water and wipe the cooktop surface with a clean, dry
paper towel. If any residue remains, repeat the steps listed above as
needed.
Note:
• Damage to your glass surface may occur if you use scrub pads
other than those recommended.
51
HEAVY BURNED-ON RESIDUE
• Allow the cooktop to cool.
• For additional protection, after all residue has been removed, polish the
entire surface with ceramic cooktop cleaner and a paper towel.
Cleaning Methods:
• While the cooktop is still warm, use a single-edge razor blade scraper at
approximately a 30° to 45° angle against the glass surface and scrape
the soil. It will be necessary to apply pressure to the razor scraper in order
to remove the residue.
• When the cooking surface is completely cooled, spread a few drops of
ceramic cooktop cleaner on the entire burned residue area. Using a non-
scratch cleaning pad for ceramic cooktops, rub the residue area, applying
pressure as needed. Leave the cleaner on for 10 minutes before rinsing it
off.
• Rinse with clear water and wipe the cooktop surface with a clean, dry
paper towel.
Note:
• Do not use a dull or nicked blade.
METAL MARKS AND SCRATCHES
• Cookware with rough or uneven bottoms can mark or scratch the cooktop
surface. Carefully check the bottom of pans.
• Do not slide metal or glass across the cooktop surface.
• Do not use cookware with any dirt build-up on the bottom.
• Always clean the cooktop surface before cooking.
• Be careful not to place aluminum baking sheets or aluminum frozen
entrée containers on a hot cooktop surface. It will leave shinny dots or
markings on the cooktop surface. These markings are permanent and
cannot be cleaned off.
52
Cleaning Methods:
• Be careful not to slide pots and pans across your cooktop. It will leave
metal markings on the cooktop surface. These marks are removable using
the ceramic cooktop cleaner with a non-scratch cleaning pad for ceramic
cooktops.
• If pots with a thin overlay of aluminum or copper are allowed to boil dry,
the overlay may leave black discoloration on the cooktop. This should be
removed immediately before heating again or the discoloration may be

55
STEAM CLEAN
The Steam Clean feature is designed to use water and a low oven
temperature to generate steam to warm the oven interior surfaces and loosen
light soils before hand-cleaning.
CAUTION
Burn Hazard
• Do not leave small children unattended near the appliance during the
cleaning cycle. The outside of the range can become hot to the touch.
• During the cleaning cycle, the oven becomes hot enough to cause
burns. Wait until the cycle is over before wiping the inside surface of the
oven. Failure to do so may result in burns.
• Oven surfaces may be hot after the cleaning cycle. Use caution and
wear rubber gloves while cleaning to prevent burns.
• Hot surfaces may create hot steam in wet sponge or cloth while
cleaning. If steam is evident when wiping out oven, wait until oven has
cooled slightly.
BEFORE STARTING STEAM CLEAN
• Allow the oven to cool to room temperature before starting. If your oven
cavity is above 150°F (65°C), HOT will appear in the display when you
attempt to select Steam Clean mode.
• Remove all items from the oven, including oven racks.
• Wipe any heavy spillovers or excess debris. Scrape off and remove any
burnt-on debris with a plastic scraper. (Suggested plastic scrapers
includes hard plastic spatula, plastic pan scraper, plastic paint scraper,
and old credit card.)
• The range should be level to ensure that the bottom surface of the oven
cavity is entirely covered by water at the beginning of Steam Clean.
• For best results, use distilled or filtered water. Tap water may leave
mineral deposits on the surfaces.
• For improved softening of tough stains, spray inside surfaces with water
spray bottle or wipe surfaces with a wet sponge before starting.
56
SETTING STEAM CLEAN
Start with oven at room temperature.
1. Remove oven racks and accessories from the oven.
2. Scrape off and remove any burnt-on debris with a plastic scraper.
3. Pour 10 oz or 300 ml of water onto the bottom center of the oven cavity.
The indentation on the oven bottom should be fully covered to submerge
all soils.
Note:
• For improved softening of tough stains on the walls and in the
corners of the oven, wipe inside surfaces with a wet sponge.
4. Close the oven door.
5. Press and hold Broil and Cook Time at the same time to select Steam
Clean mode.
Note:
• If your oven cavity is above 150°F (65°C), HOT will appear in the
display and prevent Steam Clean mode to be selected.
6. Press Start.
The Steam Clean cycle will run for 25 minutes by default. Keep the oven
door closed.
Note:
• If the oven door is opened at the time Start is pressed, the oven will
turn on when the oven door is closed.
• Press Cancel/Off to cancel Steam Clean at any time.
57
7. After the Steam Clean cycle, soak up any remaining water and clean the
oven cavity immediately by scrubbing with a soft, damp, non-abrasive
sponge or cloth. Place a towel on the floor in front of the oven to capture
any water that may spill out during hand-cleaning.
Note:
• Place a towel on the floor in front of the oven to capture any water
that may spill out during hand-cleaning.
8. If some light soils remain, repeat the above steps, making sure to
thoroughly soak the soiled areas. Once the oven cavity is cleaned, wipe
any excess water with a clean dry towel.
9. Replace racks and any other accessories.
