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

This synchronous turntable motor rotates the glass tray inside your microwave to help food heat evenly. Replace it to restore smooth, consistent rotation if the tray has stopped turning, stalls intermittently, or makes unusual noises from the base.

• Drives the turntable via the center coupler to rotate the glass tray at a steady speed
• Promotes even exposure to microwave energy for more uniform heating
• Typical failure symptoms: tray won't turn, rotates only intermittently, or emits grinding/buzzing sounds from underneath
• If power reaches the motor but it doesn't run, the internal windings or gear set may be seized

• Disconnect power to the microwave before servicing
• If mounted over a range, remove the unit from the cabinet with assistance
• Access is typically from the bottom panel; note wire positions and shaft orientation before removal
• After installation, briefly test rotation before full reassembly; inspect the coupler and support for wear
