Thumping Noise or Food Wobbling in Microwave

Thumping Noise or Food Wobbling in Microwave

If your KitchenAid microwave is making a thumping noise or if your food is wobbling, the turn table might need to be adjusted.  A thumping or rumbling sound may occur in the microwave oven if the turntable is not installed correctly or if the support roller assembly is not operating properly.

Ensure the turntable support roller assembly is operating properly by checking the following: 

  1. Remove turntable

  2. Remove and clean turntable support and rollers.

  3. Replace turntable support.

  4. Replace turntable.

  5. Place one cup (250 mL) of water on the turntable in a microwave safe measuring cup; then restart microwave oven.

  6. Verify microwave oven operation.

Note: Replace turntable immediately after cleaning. Do not operate the microwave oven without the turntable in place.
