20 Most Recent GE JVM3670 Microwave Oven Questions & Answers

Dear JD,
If you wish to repair the one you have, recommend you go to the SearsPartsDirect website, and type in you model number when asked.
You will see a nice blow-up of your model with parts listed. According to your information, you should either need a fuse, a capacitor, or a magnetron, or any combination of those.
The fuse might or might not be the problem.
The capacitor is the electronic "starter" to start the magneton, and the magnetron is the part that emits radio waves to cook the food.
Understand that, if you choose to"do-it-yourself", the capacitor is a very dangerous item, as it "holds a charge", so be certain to seek an electrical expert before you start the job.
Another choice for you would be to find a good craftsman who could fashion or design and make some panel inserts for the kitchen area if you must get a smaller microwave.
God bless your efforts.

I would first be sure the internal cooling fan is working. If not, when the magnetron overheats, its thermostat will kill all power until it cools back down.

Also, if the RF gasket somehow fell off or was left off the new magnetron, that can make it "noisy," meaning it will emit RF noise which will disrupt the microprocessor and it will act weird and shut down when you try to cook.

For free additional help and details, feel free to e-mail me directly from my site. Remind me of your full model number and detailed symptoms.

With at least two people holding up the microwave, loosen the 3 or 4 screws from above, then lower front down and lift off back rack.

The Installation manual has diagrams and instructions on how to mount it. Picture of back mounting plate.

Most of the time you have defective door switches that make the fuse blow.

#1 Turn off and un-plug the unit for 20 minutes

#2 There is as real risk of electrocuting yourself.

#3 Short the capacitor wit a screwdriver. BE READY for an arc or pop.

#4 You need a special high voltage probe to measure the high voltage. We're talking THOUSANDS of VOLTS here DANGER -DANGER - DANGER!

#4 If you want to try, you first have to DISCONNECT the capacitor from the circuit.

#5 DON'T re connect the power. Measure the resistance of the SECONDARY of the transformer (one lead goes to the capacitor). TELL ME WHAT THE MEASUREMENT IS..

#6 The rectifier could be bad (which is connected to the Capacitor) Usually - if one of th components is bad, it'll blow one of the internal fuses.

Press the "Off/Clear' button to cancel anything on the display, and reset the microwave. This is a soft reset and will simply get you out of any program you have started. Press it when the cooking complete reminder appears on the display.
Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. Plug the microwave back into the wall power supply to reset any anomalies with the microwave's memory. You will need to reset the time of day if you perform a hard reset. This should help fix the problem.

NO,If you can get to the three phillips screws directly over the vent door then you do not have to take the unit down. Unplug the unit. Remove the top three screws over the center of the louvre and then carefully lower the vent louvre. (Lowering helps me get a better grip on the louvre assembly. Then you will slide the vent louvre assembly about 1/8" to the left and then it will pull straight back and out. In the center is an aluminum cover which has a phillips screw facing you. Remove this screw and the cover plate. The light bulb is directly to the left of the inside of the cover plate. You will see the metal tabs which hold it in place. Pull the bulb housing assembly straight out (to your right) as you face the microwave. Then you will locate your halogen 120V 20W bulb. I just received this from a fellow guest on fix it and I was able to fix my unit 10 mintes ago.Also another tip was to take the inside glass out when reinserting the bulb unit back in because it does get in the way. Good Luck
