This problem is almost always due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

Details covering some previous models are in GE's bulletin here. Even if your model is not on the list, the same problem can occur.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

One way to test it is to do the following:

NOISY MAGNETRON TEST (c) 2009 and posted by William E. Miller prototech@usa.net (permission granted to FixYa to keep this on their site in this post)

(I the poster am the copyright holder on this and hereby grant permission to this site keep this on this site)


1. Unplug the microwave or turn off its breaker.
2. Open the door, then detach the control panel as shown in the video at http://www.microwavedisplay.com and swing it down, but without disconnecting the wires. )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.)
3. Plug the microwave back in.
4. Make sure neither you nor anyone else reaches in behind the control panel. There will exposed high-voltage connections.
5. Put a few cups worth of water in a microwave-safe container and place it inside the microwave.

6. Shut the door.
7. Run the microwave for about 1 minute or so on full power. (Time Cook > 1 > 0 > 0 > Start, e.g.)
8. If it does not fail, try it several more times.
9. When the water boils, change the water and try again.


NOTE:
If your model does not have a door handle, you will need to unplug the oven and reattach the control panel to be able to open the door.


If it still does not fail, I would recommend that you put it all back together and keep using it until it fails more consistently, then repeat this test.

While a microwave should never be left running unattended under any circumstances (as your owner's manual will tell you) it's even more important when one is exhibiting a failure or any odd behavior. So play it safe and stay with it while it's running!


If you or someone you know want to replace the magnetron yourself, you will need to remove the oven from the wall.

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.

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 links to helpful exploded view diagrams and part ordering help
here. I'd recommend that your bookmark this link to your favorites.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If it's under magnetron warranty, GE will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.


If it is not within the magnetron warranty, you can find links to helpful exploded view diagrams and part ordering help here.

When I start my Frigidaire FGMV174KFB microwave oven it shuts completely off and after about a minute it comes back on and does a factory reset. Any suggestions on what I should do to fix?


I appreciate your inquiry, David!

From the information you have provided your Frigidaire microwave shuts off and then will factory restart. It sounds like a possible problem with your control panel or a faulty wiring harness. I would recommend seeking assistance from a professional. They would need to properly disassemble your microwave and test each electrical component to pinpoint the problem within it. The technician has the appropriate tools needed to complete the repair without causing personal injury or any future issues with the microwave. Best of luck! -Matt

Microwave won't start


If your microwave has been worked on then possibly the nuts securing the magnetron has not been properly tightened

When Start is pressed, the oven starts but within 2 to 3 seconds the clock flickers and the oven "seizes up". I have to throw the fuse breaker to restart the clock, use the light, etc.


In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Samsung MU3250W Shut down


It could have been steam or humidity.

If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

When in doubt feel for air flow through the vents.

Good luck.

GE Microwave Problem


Can you explain, in more detail, how it "Shut Down"? How did you "Restart"? Just be pressing START? Can you describe the "Crackeling Sound"? Does it still heat? Was there any Burning Smell?
Good News is: Your Magnetron is still in the Warranty Period.
