Steve R Orange Park , FL June 05, 2017 Appliance: Model GE JVM1540LM5CS Microwave would not heat One of the door switches was loose due to broken retainer on latch board. replaced the latch board, good as new. took 30 minutes including installing the microwave. the most difficult part is puting the switches into the latch board without breaking it. also a good idea to take pictures of the orientation of the switches before removing them Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
