Customer Questions and Answers for Synchronous Motor (Microwave) by Ge

This AC synchronous motor powers the microwave's rotating mechanism—such as the mode stirrer or, on some models, the turntable—to circulate energy for more even cooking. Replacing a noisy, seized, or non-turning motor restores smooth rotation and consistent heating.

• Provides steady, low-speed rotation to drive the internal stirrer or turntable
• Promotes more uniform heating by distributing microwave energy
• Common symptoms of a failing motor: uneven heating, rattling/grinding from the cabinet, or the rotating component not turning
• Direct replacement for the original synchronous drive motor

• Disconnect power before servicing; microwaves contain high-voltage components that can retain a charge
• Access and location vary by model; remove the outer cover/grille to reach the motor
• Note shaft orientation and transfer any coupler; reuse existing mounting hardware
• Do not operate the unit with covers removed; after reassembly, test with a microwave-safe cup of water
