Steps

Goal: Confirm the symptom, rule out seating and debris, then isolate the drive fault.

Check plate seating and debris

Goal: Rule out simple causes before opening the cabinet.

  • Remove the turntable plate and confirm it sits correctly on the drive hub. The hub has a raised ring or guide; the plate must align with it. If the plate is off-center or the hub is cracked, replace the hub.
  • Remove the drive guide (ring under the plate). Inspect the cavity floor and the drive roller for spilled food or debris. Clean with a damp cloth. Reinstall the guide and plate. Test.
  • Good: Plate is seated and no debris. Turntable still does not turn—proceed to Roller and guide path.
  • Bad: Plate was misseated or debris was blocking—turntable may turn now. If it still does not turn, proceed to the roller path.

Inspect drive roller and guide

Goal: Check the drive roller and guide for wear or damage.

  • Unplug the microwave. Remove the plate and drive guide. Inspect the drive roller—the small wheel under the cavity floor. Check for wear, chips, or a flat spot. Replace if worn or damaged.
  • Inspect the drive guide—the plastic ring that sits on the roller. Check for cracks, chips, or warping. Replace if damaged.
  • Clean the roller and guide if sticky or greasy. Let dry before reinstalling.
  • Good: Roller and guide are intact and clean. Reassemble and test. If still no turn, proceed to Motor path.
  • Bad: Roller or guide was worn or damaged—replace and test. The turntable should rotate.

Test turntable motor

Goal: Test and replace the turntable motor if it has failed.

  • Unplug the microwave. Remove the plate, guide, and cavity floor panel per your model. Check your owner’s manual or search “[brand] [model] microwave service manual” for disassembly steps if unsure.
  • Locate the turntable motor under the cavity. Disconnect the motor leads and test for continuity with a multimeter.
  • If no continuity, the motor has failed—replace it with a matching part. Search for “[brand] [model] turntable motor” at appliance parts suppliers. Reassemble and test.
  • Good: Motor replaced or tests good. The turntable should rotate. If it still does not turn, call a technician.
  • Bad: All parts test good but turntable still does not turn—call a technician.

When to get help

Call an appliance technician if:

  • The microwave does not run at all (different problem—power or door).
  • You have replaced the drive roller and motor and the turntable still does not turn.
  • The microwave arcs or sparks when running.
  • You are not comfortable opening the cabinet.

Never work on a plugged-in microwave. Unplug before any repair.

Verification

  • The turntable plate rotates smoothly when you run a cycle.
  • No grinding, clicking, or unusual noise.
  • The plate is seated correctly and the drive roller and guide (if replaced) are intact.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the microwave runs but the turntable does not rotate.
  2. Plate seating and debris Check plate is seated on the hub; clean debris under the plate.
  3. Drive roller and guide Inspect and replace the roller or guide if worn or damaged.
  4. Turntable motor Test and replace the motor if it fails continuity.
  5. Call a pro Replaced parts and still no turn—or not comfortable opening the cabinet.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Whether the plate is seated correctly
  • Whether debris was found under the plate
  • Drive roller and guide condition
  • Motor continuity test result
  • Steps already tried

Does the microwave run but the turntable stay still?

Run the microwave for 30 seconds with a cup of water inside. Watch the turntable plate. If the microwave runs but the plate does not rotate, the turntable drive has failed.

Run the microwave for 30 seconds. Watch the turntable plate. Good: microwave runs but plate stays still—turntable drive fault. Bad: microwave does not run at all—different problem (power, door); see fix-microwave-will-not-heat or fix-microwave-will-not-open.

Yes No

Is the plate seated correctly and is there no debris?

The plate must sit on the drive hub. Debris under the plate can block the roller.

Remove the plate and confirm it sits on the drive hub. Check for food debris or obstruction under the plate and on the roller. Clean if needed. Reinstall and test. Good: plate seated and no debris; turntable still does not turn—proceed to roller. Bad: plate was misseated or debris was blocking—reinstall and test; if turntable turns, you are done. If still does not turn, proceed to inspect the roller.

Yes (still does not turn) No (fixed or found issue)

You can change your answer later.

Reinstall and test

Reinstall the plate and test. If the turntable turns, you are done. If it still does not turn, proceed to inspect the drive roller and guide.

Done

Is the drive roller worn or damaged?

The drive roller is the small wheel under the cavity floor. Check for wear, chips, or flat spots.

Unplug the microwave. Remove the plate and drive guide. Inspect the drive roller. Worn or damaged: replace the roller, reassemble, test. Good: roller looks fine—proceed to motor.

Yes No

You can change your answer later.

Replace drive roller and test

Replace the drive roller with a matching part. Reassemble and test. The turntable should rotate. If it still does not turn, proceed to test the motor.

Done

Does the turntable motor have continuity?

The motor is under the cavity floor. Test with a multimeter for continuity.

Unplug the microwave. Remove the plate, guide, and cavity floor panel per your model. Locate the turntable motor. Disconnect motor leads and test for continuity. No continuity: motor failed—replace it. Continuity: motor good—check drive guide for cracks; if good, call a technician.

Yes (good) No (failed)

Frequently asked questions

Why would a microwave turntable stop turning?
Common causes: the plate not seated on the drive hub, food debris blocking the roller, a worn or broken drive roller, a cracked drive guide, or a failed turntable motor. Check seating and debris first; then inspect the roller and motor.
Can I fix a microwave turntable that will not turn myself?
Yes, for most models. Seat the plate correctly, clean debris, and inspect the drive roller and guide. Replacing the roller or motor requires unplugging the microwave and opening the cabinet—follow your service manual. Call a technician if you are not comfortable—microwaves contain high voltage.
When should I call a technician for a microwave turntable that will not turn?
Call an appliance technician if you have replaced the drive roller and motor and the turntable still does not turn, if the microwave arcs or sparks when running, or if you are not comfortable opening the cabinet. Never work on a plugged-in microwave.
