Richard S Boulder , CO September 23, 2016 Appliance: Model GEJVM1540DM5BB Ge over stove microwave turntable stopped working and microwave would not heat Checked online and found a video of how to access the door switches. It was very easy. Only required the removal of three screws to remove front panel to access the switches. Checked all three switches with a continuity tester and located one failed switch. I replaced the bad switch, it appeared somewhat burned, and everything works great, now. The microwave oven is only four years old. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
