We have a GE over-the-range microwave, Model JVM1650WB 003, that was in
the house already when we moved in over a year ago, so I don't know how
old it is. All has been fine until the last week or two, when it will
sometimes make grinding noises and the turntable will stop turning.
Turning off the turntable option stops the noise, of course.
Is there a simple DIY solution to this problem? -- Other than not using
It looks like a fairly new (2000 model) unit. That grinding noise
sounds like the gears in the small motor that turns the table. It's
not too difficult to change after removing the whole unit and taking
the cover off. The motor is probably $30-40, but that is just a guess.
If you have the oven built in and need exactly that sizing then it
certainly pays to have it fixed in this case. If you are not fixing it
your best bet would be to remove the unit yourself and take it
somewhere, which would save a service call. You can call GE and get a
price on the part for starters. They also offer service help for a
If your model is not designed for use without the turn table then do
not try to use it that way as there will be hot spots in the oven.
Food will cood unevenly and burn.
In my opinion, the turntable is a failed invention to make people feel
better about the even cooking of their oven, when in fact, a hidden
stirer does a better job and is the more trouble free, life of product,
The serial # is required to check the manufacturing date...
Remove the glass tray and clean the wheels on the ring...might
help...but most times this is a bad turn table motor.
Replace the drive motor...
Drive motor, glass cooking tray.
Fairly easy to change, remove power, remove the bottom panals screws to
access the motor.

Perhaps! The motor that rotates is basically a simple AC motor etc.
Design of m.wave 'may' make it easy to just get at the bottom of the unit?
And if you are not electronics capable; two very serious warnings.
1) There is some 6000 volts DC around the power supply and magnetron. That
6000 volts is some 500 to 1000 watts of electrical energy which is
potentially lethal if 'one finger' is in the wrong place.
2) It is a microwave radio transmitter producing some 500 or more watts of
radiation (that's what cooks the food in minutes or seconds). Do not stand
near it or operate it when case is open. Make sure it is correctly closed up
with all the RF (Radio Frequency) sealing edges properly meshed, screws back
in place etc. Best to use one of those cheap m.wave radiation meters
(About$15) to ensure radiation is not leaking out around the door or the
edges. Such radiation could affect (i.e. cook or cause cancer) to people,
especially children, who pass nearby and/or are more of suitable height to
be exposed to m.wave radiation at counter top/table height!
Please be very careful.
