Sounds like the turntable motor or perhaps the damper motor?

My Sharp R957 turntable seems to be sticking. I've cleaned under the turntable and the support but it doesn't seem better. If I give it a push it works for a bit then slows down again.


Replacement of the turntable motor should be carried out by a qualified appliance repair service.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

But here is a basic method if you are mechanically minded and have electrical safety knowledge.

The motor assembly is fixed to the base of the oven usually with two screws and access is obtained usually by removing the inspection plate directly beneath the motor. It is usually a plug in synchronous 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, sometimes it must be cut out with sharp cutters, and disconnect the motor. Remove the motor and go and get a new one. Fit the new motor and fit the inspection cover back on the base by turning it to fit and using an extra screw fix it then 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.

Faulty microwave function on the SHARP R-957 model (900watt)


This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample photo for a typical damper assembly.

Check first the motor coupling under the turntable, if that is not the problem , then test and eventually replace the turntable motor.

Sharp r957, turntable has stopped


You can see and hear 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. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site. The best place to order Sharp parts is Tritronics.

UPDATE: GE Spacemaker XL1800 Microwave


JVM1850BD002 is a correct model number. This is a GE made by Samsung. It sounds like the motor or coupler is bad. More likely the motor. If you grab the motor shaft and try to gently turn it, it may grind or slip a lot. That's a sign of a bad motor. If the coupler is bad, it will be cracked or broken, causing it to slip on the motor shaft or the turntable itself. The coupler is reference 40, and the motor is reference 43 on this handy exploded view drawing: http://genet.geappliances.com/IPCNet/Dispatcher?REQUEST=IPCNETGETPDF&file=00000000/00016500/00016593.p01.pdf (copy & paste whole URL) Here is the GE part price info on these two parts: DESCRIPTION DRAWING PART NO. PRICE MOTOR-SYNCHRONOUS 43 WB26X10038 $46.00 COUPLER 40 WB06X10144 $8.75 If the motor is bad, you might be able to find the Samsung part number printed on the motor label and look it up at http://www.samsungparts.com They often have parts for far less than the expensive GE parts.
