Banging on the side by the control panel also works on my jvm3160rf5ss. I’m confused cause the ge repair video calls a part a thermal fuse. GE lists no such part but calls it a thermostat. I took that part out and it tested bad, but then I read while ordering said part, it’s a thermostat and will test bad as a fuse. I put the part back in and presto the microwave worked. That lasted three days. Soo, researching this again I read about smacking it on the side. It’s working again , for now???
