READ AND SAVE THESE INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
WARNING
If the information
in this manual is not followed exactly, a fire or
electrical shock may result that could cause property damage,
personal injury or death.
• Read all instructions before using
the microwave oven.
• Read and follow the specific
"PRECAUTIONS TO AVOID
POSSIBLE EXPOSURE TO EXCESSIVE
MICROWAVE ENERGY" found in this
section.
• The microwave oven must be
grounded. Connect only to properly
grounded outlet. See "GROUNDING
INSTRUCTIONS" found in this
section and in the provided
Installation Instructions.
• Install or locate the microwave
oven only in accordance with the
provided Installation Instructions.
• Some products such as whole eggs
in the shell and sealed containers –
for example, closed glass jars – are
able to explode and should not be
heated in the microwave oven.
• Use the microwave oven only for its
intended use as described in the
manual. Do not use corrosive
chemicals or vapors in the
microwave oven. This type of oven
is specifically designed to heat,

for industrial or laboratory use.
•
• Do not operate the microwave
oven if it has a damaged cord or
plug, if it is not working properly, or
if it has been damaged or dropped.
• The microwave oven should be
serviced only by qualified service
personnel. Call an authorized
service company for examination,
repair, or adjustment.
• Do not cover or block any openings
on the microwave oven.
• Do not store this mi crowave oven
outdoors. Do not use the

IMPORTANT SAFETY INSTRUCTIONS
• To reduce the risk of fire in the oven
cavity:
- Do not overcook food.
Carefully attend the
microwave oven when paper,
plastic, or other combustible
materials are placed inside
the oven to facilitate cooking.
- Remove wire twist-ties from
paper or plastic bags before
placing bags in oven.
- If materials inside the oven
ignite, keep oven door closed,
turn oven off, and disconnect
the power cord, or shut off
power at the fuse or circuit
breaker panel.
- Do not use the cavity for
storage purposes. Do not
leave paper products, cooking
utensils, or food in the cavity
when not in use.
• Do not mount over a sink.
• Do not store anything directly on
top of the microwave oven when

PRECAUTIONS TO AVOID POSSIBLE
EXPOSURE TO EXCESSIVE
MICROWAVE ENERGY
• Use care when cleaning the vent-
hood filter. Corrosive cleaning
agents, such as lye-based oven
cleaners, may damage the filter.
• Do not attempt to operate this
oven with the door open since
open-door operation can result in
harmful exposure to microwave
energy. It is important not to defeat
or tamper with the safety
interlocks.
• Do not place any object between
the oven front face and the door or
allow soil or cleaner residue to
accumulate on sealing surfaces.
• Do not operate the oven if it is
damaged. It is particularly
important that the oven door close
properly and that there is no
damage to the:
a. Door (bent),
b. Hinges and latches (broken or
loosened),
c. Door seals and sealing
surfaces.
• The oven should not be adjusted or
repaired by anyone except
properly qualified service
personnel.
RADIO INTERFERENCE
1. Operation of the microwave oven may cause interference to your radio, TV or
similar equipment.
2. When there is interference, it may be reduced or eliminated by taking the
following measures:
a. Clean door and sealing surface of the oven.
b. Reorient the receiving antenna of radio or television.
c. Relocate the microwave oven with respect to the receiver.
d. Move the microwave oven away from the receiver.
e. Plug the microwave oven into a different outlet so that microwave oven
and receiver are on different branch circuits.

GROUNDING INSTRUCTIONS
ELECTRICAL REQUIREMENTS
WARNING ELECTRIC SHOCK HAZARD
Observe all governing codes and ordinances.
Required:
• Plug into a grounded 3 prong outlet.
• Do not remove ground prong.
• Do not use an adapter or an extension cord.
• Failure to following these instructions can result in death, fire, or electrical
shock.
Recommended:
• A 120 VAC, 60 Hz, only, 15 or 20 A electrical supply with a fuse or circuit
breaker.
• A time-delay fuse or time-delay circuit breaker.
• A separate circuit serving only this microwave oven.
For all cord connected appliances:
The microwave oven must be grounded. In the event of an electrical short circuit,
grounding reduces the risk of electric shock by providing an escape wire for the
electric current. The microwave oven is equipped with a cord having a grounding
wire with a grounding plug. The plug must be plugged into an outlet that is
properly installed and grounded.
WARNING: Improper use of the grounding plug can result in a risk of electric shock.
Consult a qualified electrician or serviceman if the grounding instructions are not
completely understood, or if doubt exists as to whether the microwave oven is
properly grounded.
Do not use an extension cord. If the power supply cord is too short, have a qualified
electrician or serviceman install an outlet near the microwave oven.

MICROWAVE DRAWER CARE
GENERAL CLEANING
To avoid damage to the microwave drawer caused by arcing due to soil buildup,
keep cavity, drawer, microwave inlet cover, and area where the drawer touches the
frame clean.
Always follow label instructions on cleaning products.
Clean with mild soap, water, and a soft cloth or sponge or as indicated below.
Exterior
• Clean the outside with mild soap and water; rinse and dry with a soft cloth. Do
not use any type of household or abrasive cleaner.
Stainless Steel Surface
• Wipe with a soft damp cloth and polish with a soft dry cloth to maintain its
beauty. There are also a variety of products designed especially for cleaning
and shining the stainless exterior of the microwave drawer. Follow cleaning
product directions carefully.
Front Side of the Drawer
• Wipe the window on both sides with a soft damp cloth to remove any spills or
spatters. Metal parts will be easier to maintain if wiped frequently with a soft
damp cloth. Avoid the use of spray and other harsh cleaners as they may stain,
streak or dull the drawer surface.
Control Panel
• Activate the control lock to lock the control panel before cleaning. (See "Control
Lock" section.) Wipe the panel with a cloth dampened slightly with water only.
Dry with a soft cloth. Do not scrub or use any sort of chemical cleaners.
Interior
• Wipe with a soft damp cloth. DO NOT USE ABRASIVE OR HARSH CLEANERS OR
SCOURING PADS. For heavier soil, use mild soap; wipe clean with a soft damp
cloth. Do not use any chemical oven cleaners.
17

Microwave Drawer Guides
• Remove the food crumbs from the microwave drawer guides. Wipe with a soft
dry cloth in order to keep the microwave drawer opening and closing smoothly.
Waveguide Cover
• Keep the waveguide cover located on the inside top of the microwave drawer
area clean to assure good microwave performance. Carefully wipe with a soft
damp cloth any food spatters from the surface of the cover immediately after
they occur. Built-up splashes may overheat and cause smoke or possibly catch
fire. Do not remove the waveguide cover.

TROUBLESHOOTING
First try the solutions suggested here that may help you avoid a service call. If you
need further assistance or more recommendations, refer to the limited warranty
page or the contact information at the end of this manual.
If you experience Recommended Solutions
Microwave drawer
will not start or
operate
Check the following:
• Household fuse or circuit breaker: If a household fuse
has blown or a circuit breaker has tripped, replace the
fuse or reset the circuit breaker. If the problem continues,
call an electrician.
• Magnetron: Try to heat 1 cup (250 mL) of cold water for 2
minutes at 100% cooking power. If water does not heat,
check if the drawer is firmly closed and try again. If
microwave drawer still does not operate, call for service.
• Drawer: Check and remove any packaging material
attached to inside of the drawer or below the drawer,
then firmly close drawer.
If a message "Food" appears in the display, the drawer
has been closed for 5 minutes or more without the
microwave oven being started. This occurs to avoid
unintended starting of the microwave oven. Open and
close the drawer, then start the cycle again.
• Timer: When the timer is running, cooking functions
cannot be operated.
• Control: Make sure control is set properly. Make sure
Control Lock is not activated. Make sure Demo mode (on
some models) is OFF.
Arcing in the
microwave drawer
• Soil buildup: Soil buildup on cavity walls, microwave inlet
cover, cooking rack supports, and area where the drawer
door touches the frame can cause arcing. See
"Microwave Drawer Care" section.
• Cookware: Use microwave-safe cookware only.
