William C Newtown , CT March 19, 2018 Appliance: Model GE (2008) JVM1740DM1WW Our microwave turntable and microwave generator stopped working the display & other functions were fine Searching online for these symptoms turned out the most likely problem was in one of the door switches. I ordered a door switch and installed it in 15 minutes. Everything is as good as new. For a $25 switch, we saved the $300 for a new microwave. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
