Jane for Model Number GE Microwave Model JVM1540DN1WW After a power failure everything in my house worked beautifully including the microwave EXCEPT it does not heat. I am a 70 year old women with respect for electricity, but little funding and the house has a purchase offer on it! I replaced the diode, (reasonable inexpensive and another forum suggested it) but it did not help. In the case of a power failure/surge, what is the first line of resistance? Logic should be a fuse. I have not found where answers clarify a microwaves line of defense/failure. I would think a the unit should be programmed with something to stop major damage if it gets too much power? What do you think it most likely is? The thought of trashing and replacing the entire working unit (less heat) disturbs me if a minor repair is possible. The cost of a repair persons labor and trip charge (very rural location) seem to not be cost effective unless I can do it myself. Most of the items (sans the high dangerous capacity to store power after unplugging) appear to be rather straight forward with access being reasonable. I have a voltage meter but unfortunately do not know how to set the switches on it correctly for this testing. Should I give up,and just use a small table top one for cooking and just use the fans and light for my range cooking with this beautiful looking appliance?
Answer Jane, With the unit coming on but not heating and the diode being good, this would likely be an issue with one of the thermal cutoffs that are on the unit, a door switch or a magnetron that is bad. If you know someone who knows how to use a meter I would recommend testing these parts. Read More... Answered by AppliancePartsPros.com | Monday, February 26, 2018
