QUESTIONSANSWERS
Can 1 operate my microwave oven without the turntable or turn the turntable over to hold a large dish?No. If you remove or turn over the turntable, you will get poor cooking results. Dishes used in your oven must fit on the turntable.
Can 1 use a rack in my microwave oven so that 1 may reheat or cook on two levels at a time?You can use a rack only if the rack is supplied with your microwave oven. If you use a rack not supplied with the microwave oven, you can get poor cooking performance and/or arcing.
Can 1 use either metal or aluminum pans in my microwave oven?You can use aluminum foil for shielding (use small, flat pieces), small skewers, and shallow foil trays (if tray is not taller than % in (19 mm) deep and half filled with food to absorb microwave energy). Never allow metal to touch walls or door.
Is it normal for the turntable to turn in either direction?Yes. The turntable rotates clockwise or counter- clockwise, depending on the rotation of the motor when the cooking cycle begins.
Sometimes the door of my microwave oven ap- pears wavy. Is this normal?This appearance is normal and does not affect the operation of your oven.
What are the humming noises that 1 hear when my microwave oven is operating?You may hear the sound of the transformer when the magnetron tube cycles on.
Why does the dish become hot when 1 microwave food in it? 1 thought that this should not happen.As the food becomes hot it will conduct the heat to the dish. Be prepared to use hot pads to remove food after cooking.
What does "standing time” mean?“Standing time” means that food should be removed from the oven and covered for additional time to allow it to finish cooking. This frees the oven for other cooking.
Why does steam come out of the air exhaust vent?Steam is normally produced during cooking. The microwave oven has been designed to vent this steam out the vents.
Can 1 pop popcorn in my microwave oven? How do 1 get the best results?Yes. Pop packaged microwave popcorn following manufacturer’s guidelines or use the preset POPCORN pad. Do not use regular paper bags. Use the “listening test” by stopping the oven as soon as the popping slows to a “pop” every 1 or 2 seconds. Do not repop unpopped kernels. Do not pop popcorn in glass cookware.

If you experienceRecommended Solutions
Nothing will operateCheck 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.
Microwave oven will not operate■ Magnetron: Try to heat 1 cup (250 ml.) of cold water for 2 minutes at 100% cooking power. If water does not heat, try the steps in the bullets below. If microwave oven still does not operate, call for service.
■ Door: Firmly close door. On some models, if a packaging spacer is attached to the inside of the door, remove it, then firmly close door. If a message about the door appears in the display, the door 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 door, then start the cycle.
■ Control: Make sure control is set properly. Make sure Control Lock is OFF. Make sure Demo mode (on some models) is OFF.
