Tried making a bag of popcorn Saturday night and thought we had a bad bag that didn’t pop, tried another one and the same thing. That’s when my wife said the microwave smelt bad. I’ve checked the capacitors because I have a HVAC background and I recognized those parts and on other postings they said to check them, but that’s not the problem. I’m not sure how to check the diode if that’s an issue. Please Help!!
There is a pretty simple test, but you have to be careful not to electrocute yourself. Open the control panel and run the microwave watching the parts inside to see which one will produce a smoke and/or smell. Post the results.

Diode or h.v assy giving off smell, trying to get to the mag to try to test. From what I’ve read if the diode is bad the mag is probably shot too. Also what kind of reading would I get from a good diode? My meter has a doide function. Do you have to check them in the right direction?
If you do have an ohmmeter then check the diode, transformer windings and magnetron for continuity.
The magnetron has to be tested for continuity between each terminal and ground. Any reading except "∞" means it’s bad.
You can find the instructions on how to test the diode in one of our previous posts: http://forum.appliancepartspros.com/microwave-repair/19868-diode-testing.html

Checked the diode with the test you posted for me thanks. I have 6volts each way throught the diode. Looks like the diode is bad.
Magnetron tested open between ground and all terminals, but the high voltage transformer had continuity between a wire that goes to the capacitor and ground. The rest were all open could that mean that the transformer is bad?

The diode is bad. No doubt about it. The transformers test looks OK.

Thanks Gene I got the diode today and so far the microwave works great thanks for all the advice.
You are welcome. I"m glad you were able to fix it.

Gene, I have the same problem but I have a GE jvm1660sb004. I have pulled the Diode of and it’s open, but I don’t know how to get to the H. V. Transformer or the magnatron to test it. Can you help.
Thanks Jason
Hi Jason,
The diode is definitely bad and very often the magnetron continuity test does not show its real condition. The diode for this model is very expensive and there is a very high risk to damage a new part because of a faulty magnetron. On an other side, the new magnetron comes as a kit, including the new diode as well. So I would recommend to order the magnetron kit.

My oven/broiler stopped working. I hear a click when I set it, but nothing happens. Is it possible that it needs a fuse? If so how do you change it?
Any other ideas? Neither of the elements are heating up at all.
The stove part works fine.
It is all electric.
Thanks,
Robin
