Sophia for Model Number JVM1540DM I have a GE microwave oven that will not heat. Everything is working perfectly. There was a very loud humming sound just before it stopped heating. Thank you.
Answer Sophia, Microwaves that don't heat and have a loud hum noise usually indicates and issue in the high side components, and usually a faulty diode WB27X35382 or magnetron WB27X10927. These are hi voltage components and you have to be careful when you're dealing or working with them. To access and test them you'll need to remove the machine from the cabinet and remove the outer cabinet casing. Read More... Answered by AppliancePartsPros.com | Tuesday, April 23, 2013
