Microwave turntable rotates intermittently or jerks during operation.

Safety first: Unplug the microwave before handling internal parts.

Steps:

• 1. Clean support system: Remove the glass tray and roller ring. Clean the ring wheels and cavity floor thoroughly.
• 2. Inspect tray: Check the glass tray for warping or chips that could cause binding.
• 3. Check coupler fit: Ensure the turntable coupler fits snugly on the motor shaft and is not cracked.
• 4. Test without load: Run the microwave briefly with only the coupler installed. If the coupler still hesitates, the motor may be weak and should be replaced.
