Question about Whirlpool Microwave Ovens
I assume this is Whirlpool model GH4175sp?
This answer also assumes that yours does not allow for keypad control of the turntable.
You can see and hear a video of how a turntable motor should sound when you rotate it by hand.
If yours 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. You may have to cut the cover off with snips, then use a screw when reassembling it.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Hi - Possibilities of the turntable not spinning are either it is turned off, damaged or the support itself is damaged as well. Confirm that the power supply is not faulty or defective. Contact a professional to move forward accurately.
