Turntable stopped working. Nothing wrong with the plastic coupler. Replaced motor and still not working. Thought motor was bad, so requested a replacement. Installed replacement, and the turntable is still not working.
What else should I check?

The control board.

Did the cooktop lamps recently blow?

If so, the surge could have damaged the control circuit board, which can be repaired.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.

Also, the stirrer motor and turntable motor are both powered by a 21VAC tap off the internal cooling fan motor.

Are the fan and stirrer working when you try to cook?

If not, the then the fan motor or the turntable motor relay may be bad.

Or it may simply be a damaged turntable motor coupler.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
