Customer Questions and Answers for Turntable Motor (Synchronous) by Lg

This synchronous motor drives the microwave's glass turntable at a steady speed so food rotates for more even heating. Replace a weak or seized motor to restore smooth tray movement and consistent cooking performance.

• Provides slow, consistent rotation of the glass tray during cook cycles
• Helps promote more even heating by turning food under the magnetron
• Typical symptoms: turntable not turning, intermittent or jerky rotation, or humming without movement
• Located beneath the oven cavity, driving the coupler from below

• Disconnect power before servicing; microwaves contain high-voltage components that can retain a dangerous charge
• Access is typically from the bottom; remove the bottom cover and mounting screws to reach the motor
• Transfer the two wires one at a time to the new motor and ensure the shaft fully engages the turntable coupler
• Reinstall the cover and test rotation first without the glass tray, then with the tray and support
