The resistance between the terminals should be low, but not zero. These are the terminals that feed the heater/cathode. It draws a fairly significant current at a low voltage. To heat up, it must have some resistance.

There should not be any continuity between either of these terminals and the case. If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0

I had the same problem with the fan not wanting to shut off after the repair. Once I set the clock though I was able to push the button to shut the fan off. So try setting your clock first and see if that helps.

This is a common problem, and they're often intermittent. You'll need a new touch screen.

I had this mute problem and found that unpluging it for 1 to 2 min. and the problem cleared.

GE Microwave ovens, and Microwave Ovens produced by GE but released under different brand names, have had several power problems for the past 20 years. Because it is so easy to sell parts and charge outrageous rates for repair GE never corrected the problems. They just continued it in the next model. They found that you would most likely purchase a new unit rather than paying $75. for a service charge, and $150. for labor plus parts (if out of warranty period).
Most failures were cold solder connections on the power relay board. These would come completely dis-connected after arcing and burning away the solder. Could be 1 month, could be years, but they knew it would happen. This power relay board feeds 120volts to the LV (low voltage) side of the HV (high voltage) Transformer. No High Voltage,,No cook. Everything seems to run normal, but if you listen carefully you will not hear the low tone from the HV Transformer. Over my thirty years in the business I have re-soldered rather than replace so many I couldn't count.
Next to that, a defective Magnetron.

Hello Smoore66, USE CAUTION: Your first microwave experience will be fine... In order to take out your main power it has to be early in your control circuitry. Power Board was a good guess but there's also a main fuse... (usu: MAGNETRON). If you are going to work on it YOURSELF ("diy") be VERY careful to remember ALL COVERS must be in place before EVER energizing the MAGNETRON (DANGEROUS High FREQ radio). Parts abound.... even on eBay & AMAZON (I'll post APPLIANCE PART sales below) there ae SERVICE GUIDES for sale... Helpful hints & how to videos at the parts houses (below). I'd say it would be the ultimate in RECYCLING.... but a MICROWAVE is a dangerous appliance: Weigh your options carefully Good Luck eBay (price ideas & look) 17results for JVM1640 appliancepartspros Search Over 2 1 Million Appliance Parts repairclinic Appliance Parts Lawn Mower Parts Heating Cooling Parts 365 day returns partselect jvm1640 Parts List

It's what, about 7or 8 years old? I'd buy a new one on sale. Probably not worth messing with just to squeeze out another year or two. You can pull out the Capacitor and take it to any electronics appliance repair place and have it checked for little or nothing, but if it's bad and you order a new one you have no microwave for a while. IF that's the ONLY thing wrong you're back in business.

Yes it is definitely the magnetron and yes you could change it your self if you are good with electronics and tools (considering that the MAGNETRON DRIVER CIRCUIT is OK) but it is normally cheaper to buy a new microwave oven

Sorry!

first you need to take the grill off the front of the micro there should be two screws on the very top of the unit that allow you to take the grill cover off there also should be two screws in the cabinet above the micro that hold the unit in place some models have a silver hook or latch on the left side that you pull forward to release the unit from the back plate do not pull on this till you have taken out the two set screw on top of the cabinet after doing this the micro should come down

We put false doors on the back of the peninsula, mounted the wall mounts on the inside of these doors and then connected it to the top.

First check your electrical panel breaker before calling for service.
