How to Replace a Microwave Turntable Motor

Open the microwave door, and carefully remove the turntable tray. Also, remove the frame that the turntable is positioned on. Both the turntable and the frame are not secured in the oven, so removing them is a quick process.

Remove the bottom panel of the microwave. The Microwave Wizard website explains that the number of screws securing the panel varies depending on the manufacturer and specific microwave. Once the bottom panel is loosened, disconnect its wiring harness in order to completely remove the panel.

Locate the turntable motor. The Microwave Wizard website explains that the motor compartment should be positioned below the center of the microwave. Unscrew the motor, disconnect the wires, and remove it from the microwave.

Determine the specific part number for the turntable motor so that a correct replacement can be purchased or ordered. Position the new motor into the shaft in the bottom of the microwave. Screw the motor securely into place.

Test the microwave to make sure that the turntable motor is operating correctly. The Microwave Wizard website explains that the motor can make noises if it was not positioned evenly in the shaft. Reconnect all of the wires that were detached when removing the old motor.

Reinstall the microwave's bottom panel parts, and secure all of the screws in place. Reposition the turntable frame in the bottom of the microwave and place the turntable on top of it. Test the microwave in order to make sure that everything is working correctly.
