Things You'll Need
Mild dish detergent
1 cup water
If your KitchenAid microwave oven fails to operate properly, troubleshoot the appliance and determine if repairs or adjustments can be performed at home. Minor issues are often the result of overlooking simple things. Internal problems require servicing by a qualified service technician. Do not attempt to open the microwave and perform repairs without experience. You can cause property damage and personal injury.
Remove the spacer attached to the inside of the microwave oven door and close the door. The spacer prevents the door from closing completely. The microwave will not operate if the door does not fully close.
Firmly press the "Start" key. All functions require pressing the "Start" button to begin cooking.
Check the display. If the display shows a lock icon, deactivate the Child Lock to unlock the control panel buttons. Press and hold the "Cancel" or "Start" button for five seconds. Two tones will sound and the lock icon will disappear. The microwave will resume normal operation.
Clean the turntable support if the turntable does not operate. Remove the turntable and support. Clean the support in warm water with a mild dish detergent. Clean the rollers and make sure they move freely. A stuck roller can prevent the turntable from turning. Replace the support and turntable. Place one cup water on the turntable and turn the microwave on. If the turntable still does not turn, contact a qualified service technician. Do not use the microwave if the turntable does not work properly.
Test the magnetron. Place one cup water on the turntable. Set the microwave for two minutes and press "Start." Check the water. If the water did not heat, contact a qualified service technician. The magnetron may need to be replaced. Do not attempt to make this repair at home.
Inspect the cabinet and interior of the microwave for damage. If the microwave has visible damage, unplug it and call a service technician. Do not use a damaged microwave oven.
Call a qualified service technician to service the appliance if the steps above do not fix the problem. Do not attempt to take the microwave apart and make repairs.
