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, try the steps below. If microwave oven still does not operate, call for service.

Turntable alternates rotation directions
�

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

Display shows messages
�

�

A �:� or �PF� means there has been a power failure. Reset the clock. A letter followed by a number is an error indicator. Call for assistance.

�

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 happens 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.

Radio, TV or cordless phone interference
Check the following: 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.

Arcing in the microwave oven
Check the following:
�

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.

Fan running during cooktop usage
�

This is normal. The microwave oven�s cooling fan (on some models), 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.
