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, 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 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.

■

Soil buildup - Soil buildup on cavity walls, microwave inlet cover, cooking rack supports, and area where the 
door touches the frame can cause arcing. See “General Cleaning” in “Microwave Oven Care” section.

■

This is normal and depends on motor rotation at the beginning of the cycle.

■

“Enter clock” with flashing digits means there has been a power failure. Reset the clock.

■

A letter followed by a number is an error indicator. Call for assistance.

■

This is normal. The microwave oven’s cooling fan, which is separate from the vent fan, automatically comes on 
during microwave oven operation to cool the microwave oven. It may also automatically come on and cycle on 
and off to cool the microwave oven’s controls while the cooktop below is being used.

■

Proximity - Move the receiver away from the microwave oven, or adjust the radio or TV antenna.

■

Soil - Make sure the microwave oven door and sealing surfaces are clean.

■

Frequency - Some 2.4 GHz-based cordless phones and home wireless networks may experience static or noise 
while microwave oven is on. Use a corded phone, a different frequency cordless phone or avoid using these 
items during microwave oven operation.
