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.

You can fix it without the aid of a repairman. Simply unplug the microwave and remove the outer casing. There should be a few screws around the bottom edge and back panel. Once you have the unit open, look for where the power cord comes in. There should be a circuit board with a fuse mounted to it. This is your input line filter. The fuse should be a 20 amp appliance fuse that you can pick up at any hardware store (Lowe's and Home Depot both carry them). DO NOT op test with the outer casing removed. Potentials of about 14,000 volts are present in the high voltage network of a microwave oven. Close the unit up BEFORE you power it back up. Let me know if this helps.

Update: I took it back. After speaking to GE, they said that's just how it is, there is no way to silence or quiet it. I took it back and bought an LG. I love it!

SOURCE: GE microwave (jvm1740dm1bb) - Control panel inop

That model number is not quite right. I'm going to assume it's JVM1740DMBB01.

(If that's not right, please check the tag inside the oven & reply back)

The membrane keypad is not available as a separate part, so you would have to order the control panel frame which comes with a new keypad.

In this case, you simply move your circuit board into the new frame.

The part number you need is WB07X11040 and you can find helpful exploded view diagrams and order this part here for $107.00 (compared to $164.75 from GE!)

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.

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.

SOURCE: WHat part number for this GW Microwave oven thermostat?

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.

It will tell you where each one is located and what it's called, and should have the part numbers.

Three of them should read normally closed and one should read open.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

If you still need help, let us know.

The first thing to do is be sure your outlet works and works "under load." The best way to test it under load is with a toaster or hair dryer.

You can also try powering the microwave from another outlet via long extension cord, but only for testing.

If the outlet is good, then the problem will be inside the microwave.

First unplug the oven. Then see my video here which shows you how to remove the grille and controller assembly on most over the range models.

If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.

There should be a technical 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.

There were two versions of this model. The second version has more thermostats ("TSTAT" in the technical sheet).

Both version have a 20A fuse on the filter board, a magnetron thermostat (MAG TSTAT), and an oven thermostat (OVEN TSTAT).

To check the oven thermostat, you may need to remove the oven from the wall, in which case you should refer to your installation instructions. It and your owner's manual can be found online here.

If you have a version 2 model, it will also have a heater thermostat (HTR TSTAT), and a bottom thermostat (BOTTOM STAT).

When checking the thermostats, measure with a continuity checker or multimeter or ohmmeter. The fuse and all thermostats should read "closed" or near zero ohms.

(Ignore the "HOOD TCO" which will have thinner, more colorful wires. It will read open, and that is normal. If it fails, it shorts, and then the hood fan stays on all the time.)

You can order GE microwave parts here.

FixYa doesn't notify me when there's a response, so if you have other questions, please contact me directly.

Microwave VENT fan keeps running

I would say you replaced a good hood thermostat (or "TCO" / thermal cutout) with a new thermostat of the wrong type.
The oven cavity TCO and the magnetron TCO will read zero ohms continuity when tested.
They are "normally closed" devices.
But the hood vent exhaust fan's TCO is a "normally open" TCO or thermostat, so it should read open or "infinity" on a continuity check.
If the temperature under the microwave gets too high, the hood TCO opens, which turns on the vent fan until it cools back down.
I would bet that only your fuse was blown.

Ge microwave overhead 2004 model start it up and it will run for 2 seconds and it shut down have to reset time date ect,ect and it might work next time or you may have to wait till the next day before it...

There are a couple of safety thermostats under the cover that can shut down power. One is on the magnetron tube (the microwave source) in case the tube overheats. Another one is on the cooking cavity to shut the oven off if something catches fire while cooking. These interrupt the power, same as unplugging the oven, which is why you need to reset everything.

It's possible that because of the oven's age, the magnetron tube is weak enough that it's overheating when it tries cooking. As the tube ages it works harder and gets hotter. But it usually takes more than a couple of seconds for the thermostat to operate. These thermostats sometimes go bad on their own and operate too soon.

Other possible causes for power loss are a fuse loose in its holder or intermittent connections to the control circuit board.

Since troubleshooting power problems means working on the oven with the cover off and the power on, you should leave repairs to a professional. MICROWAVE OVENS USE HAZARDOUS VOLTAGES WHICH CAN KILL YOU. Let a professional check the oven and give an estimate for the repair. Given the age of the oven you may want to consider replacing rather than repairing this one, but let cost be your guide.
