Ken cj99ss How to get the Plate rotating again?It stopped without visible reason.

The motor for the rotator is bad. It has to be replaced.

Have a shop look at this---there usually is a recessed safety switch inside the jam that will prevent the unit from working with door open--sounds like the problem may be with it.

I found it here.

If it is the wheel on the turntable that squeels, wash the turntable in strong solution of washing up liquid and water.
If it does it without a turntable fitted, change the turntable motor.

Replacing the turntable motor.

The motor assembly is fixed to the base of the oven usually with two screws and access i obtained by removing the inspection plate directly beneath the motor. It is usally a plug in synchronus motor that revolves at a few revs per minute but the plastic cogs in the motors gear box fail and the motor assembly must be replaced. They are fairly inexpensive and obtainable usually from a domestic appliance repair shop.
If you feel confident, disconnect it from the mains power, remove anything in the cavity and turn it upside down if it is a tabletop model, a little more complicated if it is built in!
Remove the inspection plate and disconnect the motor. Remove the motor and go and get a new one. Re fit it and put the microwave back in its position. Plug it back in, with the turntable and plate. Put a cup of water on the plate inside of the oven and heat for 20 seconds to check the plate goes round.
Hope this helps.

> Why has the plate stopped rotating?

The turntable system typically consists of the motor, the coupler, the turntable support with rollers, and the tray.

Here is a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

There is a small motor underneath the microwave which turns the plate or turntable around.
If this is faulty then you will need a service agent to repair it.

The membrane of the touch control is shorted and must be replaced.
