TROUBLESHOOTING

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 wiring: See Installation Instructions provided with your microwave oven.
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. See "Assistance or Service" section.
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.
This is normal and occurs when the power supply in the magnetron cycles on.
This is normal and will not affect performance.
Turntable: Make sure turntable is correct-side up and is sitting securely on the turntable support.
See the "Turntable" section.
Turntable support: Remove turntable. Remove and clean turntable hub, support, and rollers. Replace
hub, support, and turntable. Place 1 cup (250 mL) of water on the turntable, then restart microwave
oven. If it still is not working, call for service. See the "Assistance or Service" section. Do not operate
the microwave oven without turntable and turntable support working properly.
This is normal and depends on motor rotation at the beginning of the cycle.
Display is showing an "Oven Status" with a letter/number code and instruction to inform
KitchenAid: The microwave oven has detected an internal problem. It has run a self-checking program
and displayed the error. Call for service. See the "Warranty" section for contact information.
Timer: See the "Timer" section.
Demo mode (one some models): See "Demo mode" section.
The microwave oven has been stored in a cold area: The fan will run slower until the microwave
oven warms up to normal room temperature.
Cooking power: See the "Microwave Cooking Power" section.
Amount of food: Larger amounts of food need longer cooking times.
Voltage: Have a qualified electrician check the electrical system in the home.
