Brenda R Peterstown , WV November 20, 2021 Appliance: General Electric Microwave SCB1001MSS001 Ge Microwave Scb1001mss001: One of the wheels on the turn table fell off and the turn table wouldn’t turn at times and would spark. How to replace Shaft Assembly (Microwave). I ordered a new shaft and a new rotating ring. It was very simple and quick to install. I just pulled out the shaft and inserted the new shaft which snapped right in. The rotating ring just lays in there. Very pleased with the repair! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
