I have a 21 year-old GE microwave in a hi-lo range (model JHP60G002) that has an intermittent problem. Everything seems OK, but it won't heat the food. The blower runs, light comes on, and the keypad/display seems normal.
The problem is also intermittent. It will work for weeks at a time, then be broken for weeks at a time.
I tried reseating the two main connectors on the Power Module board (WB27X5315 according to the GE parts web site), but that didn't help. That board is still available. Do you think it's worth spending $85 to replace that board? Exactly what does it do?
Is there anything else that could cause the problem? I asked a GE tech about it while he was repairing something else in the range, and he wasn't too helpful. I'm hoping someone here could be of more help.
