GE advantium SCA2001FSS

Many microwaves drive the turntable with a tiny belt.
Sounds like yours is broken or has jumped off the pulley.
God bless your efforts.

Yeah pal, you've not gone deep enough yet. You'll find a power wire bare inside the unit, pull it apart and tape that wire up to stop it from grounding out and blowing the fuse.

Either the coupler is cracked, the motor is defective, or the turntable support ("rotating ring asm") is worn or defective.

The service manual is here and you can find links to helpful exploded view diagrams and order parts here.

there is a fuse located underneath the outer cover, its called a ceramic fuse and is of cartridge type about 1" long by 1/8" diameter and has a white body and 2 silver ends and you can take it to a hardware store they have them but make sure to get correct amperage rating 15 or 20 amp

The screw heads on rear of GE microwave is special, what do i need to ask for to remove them.

Thanks Gayle

My Advantium was arching at the turntable. Replaced the turntable roller assembely (that hold the metal or glass plate) and the arching went away.

it is automatic, you can not turn it off. it is placed there so that the food you are heating is heated evenly. not on one side only.

tnx 4 using fixya.

I would suspect the motor is failing, but it's also possible that you have an issue with a door switch or door switch mount, depending on your model number.

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.
