Whirlpool accuwave Not Heating
the microwave listed above quit cooking. I disassembled it and checked the following:
ohmed magnatron Short between terminals, open-terminals to ground
checked voltage coming into inverter board- 120v
checked magnetron thermistor- closed
since i had voltage coming into the inverter, my thought it must be the inverter since the magnatron ohmed ok. I replace the inverter and it did not heat at first, then it started heating. I installed it (over the range) and tested it and it heated. this morning it does not heat
i can see the magnatron glowing red inside when it was working. it has made a slight hissing noise a few times (pulsating)
unfortunately, i found this forum too late....i just read that you can order parts and return the ones you do not use! How amazing is that? I just spent $120 on this microwave for the inverter and it may not be the problem.
any suggestions will be greatly appreciated. the only thing I have not tested is the voltage/signal coming into the inverter from the control panel. it is a 3 wire plug and I cannot find any information on what the voltage/signal should be into the inverter
At this point I am thinking the magnetron is bad...or could it be the control panel and the voltage/signal on the 3 wire plug....being intermittent makes it even harder to find the right part without spending more than the microwave is worth.
If you still have the 120VAC to the inverter replace the magnetron Part number: 8206079
what is the voltage/signal on the 3 wire plug to the inverter? could this affect the output of the inverter?
thanks for the quick reply:)
It's possible, but no literature can be find for this model and similar models has different wiring.
So I suggest you to try the new magnetron first. As you know it's returnable even if you install it.
