Use & Care Guide BUILT-IN MICROWAVE OVEN
This manual may cover several different models. The model you have purchased may have some or all of the features shown here. The appearance of your particular model may differ slightly from the illustrations in this manual.


The turntable can rotate in either direction to help cook food more evenly. For best cooking results, do not operate the microwave oven without having the turntable in place. See the “Assistance or Service” section to reorder any of the parts.
To Install:

Display
When power is first supplied to the microwave oven, a “:” will blink in the display. Touch CANCEL to stop the blinking. If the “:” blinks in the display at any other time, a power failure has occurred. Touch CANCEL and reset the clock if needed. When the microwave oven is in use, the display shows cooking power, quantities, weights, and/or prompts.
When the microwave oven is not in use, the display shows the time of day. When the microwave oven is sensing, sensor animation (clockwise “racetrack” movement) will be active in the display.
Start
The Start keypad begins any function. If non-sensor cooking is interrupted, touching START will resume the preset cycle. If sensor cooking is interrupted, touching START will resume the cycle only if the sensor already has estimated the cook time and the countdown is active in the display.
NOTE: To avoid unintentional operation of the microwave oven, a cooking function cannot be started if the microwave oven door has been closed for about 1 minute or more. “DOOR” will appear in the display until the door is opened and closed.
Cancel
The Cancel keypad clears any incorrect command and cancels most functions except for the Control Lock and Demo mode. It will not erase the time of day unless the display is in clocksetting mode. See “Clock” section.
The microwave oven will also turn off when the door is opened. Close the door and touch START to resume the cycle. If sensor cooking is interrupted by opening the door while the sensor is estimating the cook time and the sensor animation is active in the display, the cycle will be canceled.
Add a Minute
The Add a Minute keypad automatically starts the microwave oven at 100% power for 1 minute. Each additional touch of the control will add 1 minute of cook time, up to a total cook time of 10 minutes.
Cook time may be added to a cooking cycle at the current power level by touching ADD A MINUTE. During a manual cooking cycle, each touch of the Add a Minute control will add 1 minute of cook time, up to a total remaining cook time of 10 minutes. The Add a Minute keypad will not add minutes to a cycle that has a remaining cook time of 10 minutes or more.
Dial
Use the dial to select options, set the clock, set cook time and cook power, select food type and amount/weight, and adjust doneness.
To Use: Push dial and release to pop it out. Repeat to return dial to its flush position after each use to avoid breakage of the dial.
Select
Use the Select keypad to select a chosen function and to set the following options:
See the “Meal Prep” sections for details on using the Select keypad with the automatic cooking, reheating, and defrosting programs.
Clock
This is a standard 12-hour clock (12:00-11:59).
To Set:
To Cancel Clock:
The next time the clock is set, “12:00” will appear in the display when the clock-setting mode is entered.
Tones
Tones are audible signals that may be turned off. These tones indicate the following:
One tone
Two tones
Three tones
Four tones
Five tones
Demo Mode
The Demo mode is ideal for learning how to use the microwave oven. When set, functions can be entered without actually turning on the magnetron. The microwave oven light will come on, the fan will run, and the turntable will rotate. When the microwave oven is turned on while in Demo mode, “no” and then “HEAt” will appear in the display.
To Turn On/Off: The microwave oven must be OFF. Open the door, then touch and hold COOK for 5 seconds. Three short tones will sound. Repeat to exit Demo mode.
Control Lock
The Control Lock shuts down the control panel keypads to avoid unintended use of the microwave oven.
When the control panel is locked, none of the keypads will function. If a keypad is touched, “LOC” will appear in the display and invalid entry tones will sound.
To Lock/Unlock Control: Before locking, make sure the microwave oven is OFF. Touch and hold CANCEL for 5 seconds until 2 tones sound. Repeat to unlock the keypads.
Cooling Fan
Depending on the length of the cooking cycle, the cooling fan may continue to run after that cycle has ended. This is normal and helps eliminate moisture that may accumulate inside the microwave oven before the door is opened.
While the fan is running, “COOL” will appear in the display. The fan will turn off automatically. New cooking functions may be started while “COOL” is still being displayed.
A magnetron in the microwave oven produces microwaves which reflect off the metal floor, walls, and ceiling and pass through the turntable and appropriate cookware to the food. Microwaves are attracted to and absorbed by fat, sugar, and water molecules in the food, causing them to move, producing friction and heat which cooks the food.
Food Characteristics
When microwave cooking, the amount, size and shape, starting temperature, composition, and density of the food affect cooking results.
Amount of Food The more food heated at once, the longer the cook time needed. Check for doneness and add small increments of time if necessary.
Size and Shape Smaller pieces of food will cook more quickly than larger pieces, and uniformly shaped foods cook more evenly than irregularly shaped food.
Starting Temperature Room temperature foods will heat faster than refrigerated foods, and refrigerated foods will heat faster than frozen foods.
Composition and Density Foods high in fat and sugar will reach a higher temperature and will heat faster than other foods. Heavy, dense foods, such as meat and potatoes, require a longer cook time than the same size of a light, porous food, such as cake.
Cooking Guidelines
Covering Covering food helps retain moisture, shorten cook time, and reduce spattering. Use the lid supplied with cookware. If a lid is not available, wax paper, paper towels, or plastic wrap approved for microwave ovens may be used. Plastic wrap should be turned back at one corner to provide an opening to vent steam. Condensation on the door and cavity surfaces is normal during heavy cooking.
Stirring and Turning Stirring and turning redistribute heat evenly to avoid overcooking the outer edges of food. Stir from outside to center. If possible, turn food over from bottom to top.
Arranging If heating irregularly shaped or different-sized foods, arrange the thinner parts and smaller-sized items toward the center. If cooking several items of the same size and shape, place them in a ring pattern, leaving the center of the ring empty.
Piercing Before heating, use a fork or small knife to pierce or prick foods that have a skin or membrane, such as potatoes, egg yolks, chicken livers, hot dogs, and sausage. Prick in several places to allow steam to vent.
Shielding Use small, flat pieces of aluminum foil to shield the thin pieces of irregularly shaped foods, bones, and foods such as chicken wings, leg tips, and fish tails. See the “Aluminum Foil and Metal” section first.
Standing Time Food will continue to cook by the natural conduction of heat even after the microwave cooking cycle ends. The length of standing time depends on the volume and density of the food.
Cookware and Dinnerware
Cookware and dinnerware must fit on the turntable. Always use oven mitts or pot holders when handling because any dish may become hot from heat transferred from the food. Do not use cookware and dinnerware with gold or silver trim. Use the following chart as a guide, then test before using.

To Test Cookware or Dinnerware for Microwave Use:
Do not use cookware or dinnerware if it becomes hot and the water stays cool.
Aluminum Foil and Metal
Always use oven mitts or pot holders when removing dishes from the microwave oven. Aluminum foil and some metal can be used in the microwave oven. If not used properly, arcing (a blue flash of light) can occur and cause damage to the microwave oven.
OK for Use
Racks and bakeware supplied with the microwave oven (on some models), aluminum foil for shielding, and approved meat thermometers may be used with the following guidelines:
Do Not Use
Metal cookware and bakeware, gold, silver, pewter, non-approved meat thermometers, skewers, twist ties, foil liners such as sandwich wrappers, staples, and objects with gold or silver trim or a metallic glaze should not be used in the microwave oven.
Microwave Cooking Power
Many recipes for microwave cooking specify which cooking power to use by percent or name. For example, PL7 = 70% = Medium-High. Use the following chart as a general guide for the suggested cooking power of specific foods

Cook Time Set
Cook time may be set in the following increments, in minutes and seconds:

To Use:
The cook time may be changed at any time after touching START. The dial may be used to increase or reduce cook time. The Cook Time keypad will only add time.
Doneness
For most automatic cooking functions, the doneness of a particular food item can be adjusted by turning the dial. Increasing or decreasing the doneness adds time to, or subtracts time, from the cooking cycle.
For up to 20 seconds after cooking has started, turning the dial will change the doneness value. There are 5 settings: default, “2,” “1,” “-1,” and “-2.” The display shows “----” for the default setting.
Doneness cannot be adjusted for Defrost functions or for the Popcorn function.
Doneness cannot be decreased for Boneless Chicken Breasts function.
Sensor Cooking
A sensor in the microwave oven detects humidity released from the food as it heats and adjusts the cook time accordingly. Many sensor cycles require the covering of foods. Microwavesafe containers or steamers with loose-fitting lids are recommended. The loose-fitting lid allows enough steam to escape to be detected by the sensor. When covering foods with plastic wrap, be sure to leave a large enough vent opening to allow the steam to escape. “SC” (sensor cook) will appear in the display during sensor cooking.
NOTES:
One-Touch Sensor Cooking
A sensor in the microwave oven detects humidity released from the food and automatically sets a cooking time based on the selected pad.
NOTE: During Popcorn function, as with all microwave cooking functions, the microwave oven should be attended at all times. Listen for popping to slow to 1 pop every 1 or 2 seconds, then stop the cycle.
Use the following chart as a guide for the One-Touch keypads.

* To avoid damage to the microwave oven, do not use regular paper bags or glassware. For best cooking results, do not try to pop unpopped kernels. Use fresh bags of popcorn for optimal results. Cooking results may vary by brand and fat content. For bag sizes not listed in this section, follow directions on package. If using a microwave popcorn popper, follow manufacturer’s instructions.
To Use Baked Potato and Meal Reheat:
To Use Popcorn:
Keep Warm

Hot cooked food can be kept warm in the microwave oven. The Keep Warm function uses 10% cook power. Keep Warm can be used by itself or can be programmed to follow a cooking cycle.
To Use (for single cycle):
To Set at End of Cycle: During any cooking function, except Popcorn or Defrost, touch KEEP WARM. The Cook Time indicator will flash. Touch START. When the current cooking cycle has ended, the end-of-cycle tones will sound and then the Keep Warm cycle will automatically start. The Cook Time indicator will flash and the display will count down the warming time. Warming time may be adjusted at any time during the countdown. At the end of the Warming cycle, “END” will appear in the display and the end-of-cycle tones will sound, followed by reminder tones. Touch CANCEL or open the door to clear the display and/or stop reminder tones.
To Warm Manually: Follow instructions in “Cook Time Set” section and use 10% cooking power. See “Microwave Cooking Power” chart.
IMPORTANT: Before cleaning, make sure all controls are OFF and the microwave oven is cool. Always follow label instructions on cleaning products. Soap, water, and a soft cloth or sponge are suggested unless otherwise noted.
