JVM3160RF3SS: Fuse blowing when door is opened

Thu, 19 Dec 2024 15:56:53 -0700

Fuse blows if door is opened before end of heating. Can be opened anytime not in heating part of cycle.

Model is JVM3160 Df. How would I find the schematic for this?

JVM3160RF3SS: No power after 20amp fuse blown and replaced

Thu, 06 Nov 2025 03:35:26 -0700

Hello, second time I've tried to fix our microwave. First time successful... one of the door switches failed and blew the 20a fuse. I was able to replace the door switch and fuse and it worked again for over a year now.

This time, fuse blew again so I took it apart. The three door switches all test okay: clicking correctly and continuity test check out whether normally open or normally closed. Replaced the 20a fuse again, but when plugged back in there's no power to the control panel. Fuse is good and there's continuity across the fuse to the other contact.

The two thermal cut offs directly behind the control panel test ok, but I haven't been able to reach the "Cavity Thermostat Cutout" for testing. The unit shouldn't have reached anywhere near the 230F temperature listed to blow that, but I guess it's still possible this has failed.

Other possibilities? I see a H.V. Trans Fuse listed and it could possibly be a bad Magnetron. These or possibly a new control board?

I'm reaching the limit of my abilities as a non-licensed/weekend hack/cheapskate just trying to keep a microwave running. Time to just spring for a new one and play the "disposable appliance" game?

Thanks for any insight

Was trying to put a picture up too

JVM3160RF3SS: Why is my GE microwave bottom door switch normally open?

Sat, 14 Sep 2024 13:53:06 -0700

My microwave oven (model JVM3160DF4WW) tripped the circuit breaker when starting to heat food. I found out one thermostat was bad (open circuit). Next, I found out the middle door switch was closed whether the button was pushed or not, so it needed to be replaced. But it was odd about the bottom door switch. My impression was that it (and the middle one) was normally closed. But mine was the opposite - it was normally open and was closed when the button was pushed. Is this normal for this particular GE microwave oven model?
