It's normal for it to rotate in either direction. It has to do with the position of the motor and the instantaneous line polarity at the time the power is engaged.

But the grinding noise may indicate a problem...

You can do a quick check. You can see and hear a video of how a turntable motor should sound when you rotate it by hand:

If yours sounds like it's grinding, etc., you may have a bad motor.

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

Why do I hear a popping noise when turntable revolves counterclockwise.

If the turn table automatically picks up the tone arm and starts the record and changes after the record is over, then you are haering the gear box.

Yes it can be replaced. But first make sure the noise isn't coming from the guide roller assembly or coupler which is the plastic part in the bottom of the microwave that turns the turntable. .

The turn table goes clockwise sometimes & counter clockwise sometimes.It also makes a groumbling noise.

The motor for the turntable in these ovens is bi-directional. This is normal.

As for the noise, it is very common that the main turntable wheel track-ring under it is dirty at its wheels, or its pin-pushings have some wear. It is also posssible that the main turntable motor has become noisy from use and age.

I have had microwave ovens make a grumbly sound when one of the cooling fans are going defective.

Many thanks to e3enigma above! I removed the synch motor under the turntable; all other microwave functions work fine and the grinding noise is gone, hooray! A trip to the appliance parts store tomorrow for a replacement synchronous motor and all should be well. Thanks again!

The turntable makes grinding niose when engaged

That model number doesn't ring a bell. Is that right? Is it foreign?

Chances are the coupler and/or turntable support will be damaged or warped.

Also on some brands, the "packing" (often a rubber grommet) must be replaced.
