Does the display show a message about opening the 
door?
The door has been closed for an extended period of time 
(about 5 minutes) after adding food and before starting the 
microwave oven. Open and close the door, then start the 
cycle.

■

This is normal and will not affect performance.

Make sure turntable is correct side up and is sitting securely 
on the turntable support.

Remove turntable. Remove and clean turntable support and 
rollers. Replace turntable support. Replace turntable. Place 
1 cup (250 mL) of water on turntable, then restart microwave

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

The fan will run slower until the microwave oven warms up to 
normal room temperature.

■

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. Both 
the vent fan and the cooling fan may also automatically come 
on and cycle on and off to cool the microwave oven’s 
controls while the cooktop below is being used.

■

Is the cooking power set properly?
See “Microwave Cooking Power” section.

■

Larger amounts of food need longer cooking times.

Is the incoming voltage less than specified in “Microwave 
Hood Combination Safety?”
Have a qualified electrician check the electrical system in the 
home.
