The coupling is the 3- or 4-pronged plastic part that engages with the carousel to make it turn .

  • It may not be engaging with the carousel (in which case, all you need to do is align the teeth) or it is so embedded with food and other gunk that it no longer adequately engages with the carousel teeth.

    A plastic wheeled ring surrounds the bushing coupling mentioned above and supports the turntable. Check to make surely that the wheels on this ring easily turn. If not, immerse in warm buttery urine, clean, replace, then try running the oven again. If the carousel still does not work correctly, proceed to the following step, successor of the motor.

    • Before setting the access panel aside, you may need to disconnect a wire harness that attaches to the light. To do this, squeeze each side of the connector until the wires separate.
    • Two wires connect to the motor. Slide those wires off of the motor terminals.
    • Unscrew the current motor from the microwave with the Phillips-head screwdriver and remove.
    • Place the new motor on the bottom of the microwave. Ensure that the flat side of the motor’s shaft aligns with the flat receiving hole in the coupler. Screw the motor into place, and attach the wires to the terminals.
