Microwave Turntable Not Spinning – What Part Fixes This Problem?

Understanding the Problem
The turntable in your microwave rotates food so it heats evenly. When it stops spinning, food will heat unevenly with hot and cold spots. The most common cause is a broken turntable coupler — the small plastic piece that connects the motor shaft to the glass tray. The turntable motor itself can also burn out over time. Less commonly, the guide roller ring under the glass tray may be cracked or jammed with food debris.
Common Causes
- Broken turntable coupler
- Burned-out turntable motor
- Cracked or jammed guide roller ring
- Debris blocking the turntable track
- Faulty control board not sending power to motor

Helpful Repair Tip
Remove the glass tray and the roller ring and inspect them for cracks or debris. Spin the turntable motor shaft by hand — it should turn freely. If the coupler (the three-pronged plastic piece on the motor shaft) is cracked or stripped, replace it. If the shaft does not turn or the motor makes a humming noise but the tray does not move, the turntable motor needs to be replaced.
