Product Description

Microwave Turntable Motor Coupler Specifications

The turntable motor coupler connects the turntable motor to the tray. If the turntable on your microwave will not rotate, you may have a faulty motor coupler. The coupler commonly has a D shaped opening that fits tightly onto the motor shaft. If it is cracked, or worn it will need to be replaced. This is a genuine OEM replacement part sourced directly from the manufacturer.

The new part was too thick for the worn out plastic ring which is obsolete.
Needed to raise the part to match the ring. I used peanut butter to hold plastic shim while replacing to hold it in place. Built in Oct. 2009.

Microwave will not heat up unless turntable is turning, is this normal? Sometimes it turns and sometimes it doesn't. Do i need to replace the coupler and is it as simple as just taking our the old and replacing with new.
For model number LMV1686SW

Hello Margo, thank you for your question. If the microwave is heating intermittently, I would check the door switches first. If the door switches are not functioning properly, it could cause the tray to not turn and the microwave not to heat. If the problem continues, I would look into checking the turntable tray motor. I hope this helps.
