I already checked: My circuit 20 amp breaker Both ceramic fuses, about 0 ohms Check 1 thermal fuse, 0 ohms There is a second thermal fuse I am having trouble removing to check. What else can I check or replace? Thanks
There should be a technical sheet hidden behind the controller or behind the grille. If you can't find yours, I have uploaded a copy here at my site: http://www.microwavecontrol.com/dvm1850_jnm1851_jvm1860_jvm3670_pvm1870_pvm1871_tech_sheet.pdf
I would refer you to that and to the exploded view, which you can find by entering your full model number (from the tag on the oven) here: http://tinyurl.com/gv383, where you can find GE replacement parts at affordable prices.
From the symptoms and checks you've described, I would recommend next that you check for full continuity (virtually zero ohms) across the magnetron thermostat located at ref. 62 on the exploded view.
If that checks good, you will probably need to remove the oven from the wall so you can check the thermostat (ref. 44) for full continuity (virtually zero ohms). To aid in removing it from the wall, the installation instructions are on your model's support page.
If you still have questions, feel to free to e-mail me directly at [email protected].

The problem was a defective switch. There are 3 switches on mine. 1 on the top door latch, and 2 on the bottom. one of the switches on the bottom connected the power and neutral together, unless it was activated at the same time as the other 2, causing the breaker to trip or the internal fuse to blow. When unhooking the wire going from this switch to the other switch, everything works great now. Though I still need to replace the switch.
And for Basic 1. Yes my microwave did have a fuse in it it's ceramic, I got a pack of them at Radio Shack 4 for 3$ 250V 20 Amp. There should be a wiring diagram inside the microwave, mine was inside a black bag, so it may be hard to see.
Mine was up top next to the fuse behind the Plastic Grill and then a small metal grill. Some are behind the control panel, to fix this remove the screw at the top and then slide the control panel up and it should unhinge.

Chances are if the varistor fails, it fails drastically causing a short circuit across the supply. It will sit across the supply (it will look like a thick ceramic capacitor) and you can check for continuity after isolating that at one end. If it shows low resistance (it should show almost open circuit with a Digital meter), replace it.
It need not be the culprit. If you are familiar working with High voltage circuits ( they are lethal inside a microwave ovens as the current capability is high here), you can discharge the doubler capacitor and isolate the high voltage diode to check for shorts in the HT area.

It may be a blown fuse or the thermal cutout (T.C.O.) or thermostat on the magnetron or on top of the oven cavity.
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.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
You can find
helpful exploded view diagrams and order parts by entering your full
model number from the tag on the oven here.
Accessing some
components
(especially the oven cavity thermostat) for testing and possible
replacement will require you to remove the oven from the wall and take
off the outer cover.
If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.
You can
download GE
owner's manuals and installation instructions here.
Feel free to contact me directly (and please remind me of your
full model number from the tag on the unit) for more
information & help.
We're
happy to help you with free advice and we'd appreciate your thoughtful
rating of our answer.
