Question about Frigidaire PLMV169DC Microwave Oven
The microwave was in use while the stove top below was being used and sending heavy steam onto the microwave control panel. The wife heard popping and then saw blue sparks shoot out below the control panel. No smell, flame or smoke after the event. The control panel still works fine but the microwave doesn't heat and there is a new buzzing present while trying to heat. I removed the control panel to inspect the electronics for obvious burning. The only thing I could see is the HV transformer looks to have small burn marks on the outside of the transformer body. I would like to replace the transformer but don't want to waste money if this is terminal.
With the symptoms you
have, I would most strongly suspect a shorted high voltage rectifier
diode or a bad magnetron.
It may be a problem with the transformer, but I suspect that less.
The diode is a fairly cheap fix, and the mag will cost more. The transformer may be pretty steep. But it's best to take it a step at a time.
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
Here are some links you or someone you know can use for test help, but read their safety warnings first:
(if it's not shorted, it's probably okay)
