Troubleshooting

First try the solutions suggested here or visit our website, and reference FAQs (Frequently Asked Questions)

to possibly avoid the cost of a service call.

In the U.S.A., www.kitchenaid.com In Canada, www.kitchenaid.ca

Microwave oven will not operate

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.

■

Household inverter power supply

The power source for this microwave oven is an inverter, and is
incompatible with household inverter power supplies.

■

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.

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.

Turntable alternates rotation directions

■

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

Odor and smoke coming from microwave oven during
convection cooking

■

This is normal for the first few convection cycles. The odor will
dissipate with repeated use.

Quartz bulb does not appear to be on

■

This is not unusual. See “Grill Element” in the “Features”
section.

■

Is the element still working properly?

Place 2 slices of bread on the tall grill rack, place the rack on
the turntable and close the door. Program the microwave oven
using manual grill – without microwaves – for 4 minutes. The
bread should toast dark brown. If it does not toast, call for
service.

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.

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.

Fan running after cooking is finished

■

This is normal for convection and grill use. The fan may run for
up to 10 minutes to cool the microwave oven.
