Symptoms: The microwave runs just fine, but nothing warms up no matter how long you put it in for. Troubleshooting: The transformer seems to be fine. The capacitor looks fine (to be fair, I didn't meter it, cause it is hard to reach) The magnetron has been replaced twice... It always seems to fix the problem, but after two or three weeks it stops working again. I don't see any charring on or around the magnetron like it is overheating. The large magnets don't appear to be cracked. In fact, once I remove the apparently bad magnetron, I meter it out, and it looks fine... but I put a new one in and it works again for a short time. It doesn't seem like a power issue, transformer, capacitor, diode... It seems like it's the magnetron, but I don't want to keep replacing it every month. Any ideas?

I have a Dacor DCM24S convection microwave. Both the microwave and the convection heating stopped working at the same time. All the other functions appear to work just fine -- the light, turntable, control panel, etc.. Any ideas on parts that would explain this? I found the service manual here: https://www.manualslib.com/download/898193/Dacor-Dcm24b.html. I feel like I should be able to figure out the next step based on the schematic S-1 (attached to this post), but alas I'm not quite there.

I have this ancient beast from 1987 and I'm having a real tough time trying to find any tech schematics or service manuals. It just went up and died on me one day - no lights or anything from the microwave. The main fuse was blown, so I replaced that. Now I have the control panel back online, but the magnatron and its fan don't fire up when the cooking sequence starts. I can hear the relay click...then nothing but the panel counting down thinking it's working. This is a GE SpaceSaver / SpaceMaker (label has worn off) combination range and microwave. The range functions perfectly. I got nothing from the FCC or UL databases. Here is all the info I have on the unit: Manufactured February 1987 Model: J HP69G 0J1AD. * That could be OJ1AD FCC ID: ACM9Z9008 UL Listed 368G, File No. E23718 Power: 13.2KW on 120/240v, 10.2 on 120/208v Any help would be greatly appreciated!

My GE spacesaver (JVM1430BD) stopped working in the middle of microwaving and blew the inline fuse. After some digging and testing, it turns out the capacitor was bad (continuity between the two sides). I ordered a new one with nearly the same specs (2100wvac and 0.86uF on old vs 2100wvac and 0.91uF on new). When the part came it was about 0.5" shorter than the old one but otherwise fit into the holder etc. I installed it and turned the microwave back on...everything worked again. I microwaved some water and it heated it just as expected in the same amount of time as before the capacitor went out. An hour later I was in the kitchen and noticed a very soft hum. It was coming from the microwave and was very soft. The only reason I heard it was because the fridge had stopped its cycle and everything was dead silent in the kitchen. I took the cover off thinking it was the new capacitor or the diode. The sound actually seems to be coming from the HV transformer. While the microwave still had power to it, I went ahead and unplugged the diode from the capacitor for a few seconds wondering if maybe the old diode was bad and drawing current. Humming stayed the same with the diode attached or not. I re-tested the microwave function and everything still works as expected. Before I installed the new capacitor I had checked resistance for the HV transformer and it was appropriate. I also checked the magnetron for continuity etc. and everything seemed in order. I was convinced that the only thing that went bad was the capacitor. Any thoughts on why the HV transformer is humming. Again, it is very soft but I am convinced that it is louder than it was before the switch. Could the diode be bad despite the contiued hum when I disconnected it? Is the new capacitor not functioning properly? Is the shortened length or minor discrepancy in uF to blame? Most importantly, is a humming transformer dangerous/a risk? It just sounds like a piece of electrical machinery working but it is louder than before the fix. Thanks!
