The glass plate in the microwave wouldn't rotate.
So simple!! I took the glass plate out of the microwave and removed the plastic part that it was sitting on and installed the new part. I put the glass plate back in and turned the microwave on and the glass plate started to rotate just like it was supposed to. The wheels on the old part had become flat and that's why it wouldn't rotate. No tools were needed.
Removed glass try, easly pulled ring up and off shaft and installed in reverse order aligning keyway on new part with keyway shaft, then placed glass tray back into unit. As simple as turning a door knob.
