The wheel has stopped turning. What should I do?

inside the cabinet, there is (usually) a belt that turns that gear, you will have to unplug the unit and take off the cover to get at it, probably has some grit in the belt or such, also look for missing teeth

Unfortunately there is nothing you can do but to buy a new microwave oven Once it arcs it causes burns on and in the parts and most times cleaning does nothing

Sorry, good luck

HELLO.

If by not turning mean turntable fault,the solution is given below in detail.

1 Press "Stop" to halt microwave operation.

2 Press the "Turntable" button once to turn off rotation.

3 Push the door-release button to open the microwave oven if you do not have a "Turntable" button on your control keypad.

4 Lift and remove the glass platter from the oven, then pick up the plastic track with three wheels below the platter. Set aside these parts.

5 Insert the elevated microwave cooking tray into the oven. The tray has three to four short legs that hold it above the bottom of the microwave, keeping it from interfering with the rotating bolt in the bottom center of the oven the drives the turntable. You can now place food on the elevated tray and cook normally without disrupting the drive bolt.

Thanks.

This may sound a bit nuts, but remove the glass tray and support ring. Clean the wheels and ring. Also clean the glass and microwave surface where the wheels run. Any tiny bit of debris will stop the wheels from turning, and make a rattling noise.
If that doesn't help, you may need a new turntable motor.

Check the 3 wheels on the circular plastic part that's fitted below the turntable.
It sounds like they may need some filing down. Run your fingers around the wheels to see if there are any sharp bits of plastic that could be cutting into the paintwork on the base.

Clean out the base of your oven and apply a thin film of vaseline to each of the 3 wheels. This will help rotation in future.
Remember to keep cleaning out any excess food particles that may lodge below the turntable, as these will eventually slow down or stop the rotation, which in turn means that your food is not heated evenly throughout!!!

One suggestion i would make is that in the microwave there is the turntable, lift the plate off ,then below it you will see a circular object with wheels on.I think you may have this the wrong way up, so turn it over put the plate back on top and should work.

its the circular piece on runners that is the problem

They MIGHT have a belt between the motor and the turntable drive wheel that may have gone bad, rather than the motor. The unit will have to be removed from the case to get to the innards.

If the microwave comes with a roller ring to rotate the glass turntable then I would recommend that it needs to be used when the microwave is operating, as the turntable rotates the food so it can be heated evenly.

I would recommend checking with your local Panasonic repairer he may have access to a new roller or even a second hand one to tide you over.

It will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Enamel should work, but appliance paint is better.

We're happy to help and we appreciate your thoughtful rating of our answer.

I has this problem with a Sears unit. The repairman simply removed the glass tray, cleaned all the wheels and the 3 toothed driver wheel in the middle and it became quiet. He explained that if any buildup keeps the plate from properly seating on the gear, it gets very noisy.
