How to replace Microwave Turntable Motor. After ordering both parts, i only had to replace turntable coupler. I ordered both because I was not sure how much damage had been done after leaving the heating element on for an hour or so. Fortunately only the turntable coupler was damaged, and the hub (all that was left) snapped right off. All I had to do place the slide the new coupler on and it was all fixed.
