The turntable is not rotating while cooking. It seems the stem broke. Could I just purchase the support part no AP3777090 and it will fix it. is the support part no AP3777090 include the stem attached to motor?
when I try to rotate to hear the motor and I don't think the stem was attached to the motor. is there any other part I need to purchase?
What part of the microwave I should take out to install the support part AP3777090?
The shaft that the support sits on is part of the turntable motor which would need to be replaced. The part number for the turntable motor is W10159107. In order to replace the turntable motor you will need to unplug the unit, remove the screws at the bottom of the unit that holds the base in place. Once removed the base will drop down and will allow access to the turntable motor. When you drop the base you will disconnect the wiring to the motor and take the 2 screws holding it in place out. Install the new motor and reassemble the unit.
