Re: Shorting Out

The control panel drops down (keep attached at the bottom).
Fold or cut the film to fit over the frame, and use regular scotch tape to attach it. Don't cover the little holes where the panel needs to be hooked back into. Cover as much as you can down to the group of wires on the bottom.

Hope this makes sense--not a very technical answer.

My microwave is working just fine.

So my 2 year old panasonic m/w has blown up 2 "powerboards" in 3 weeks. Turn it on and 3 seconds later there is a shorting noise and the entire thing is dead. Was told there must've been a low power

Interesting problem, I would suggest the bad power board is the result of something else. Check your outlet it may be wired wrong or with the wrong voltage.

Good Afternoon Friend,

I understand that you are noticing less noise, after about a second of starting your Frigidaire microwave, model# PLMB186CC. I suggest checking to see if the power level was changed. The blower sound will be different at levels other than "HIGH". As long as it is still heating, there is no cause for alarm. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your washer status has changed successfully. Hope this is helpful.

-Best Regards-

The Microwave runs for a short time then cuts out. The HV coil on the circuit board has an electrical overheating smell.

Hi hansb52.

With out any more information, ie make model, etc, I'll just guess it's a Panasonic. If that's true, then your inverter board is bad. Some models had free replacement boards as an "upgrade", along with a couple of other parts. Without that missing information I can't add more.

Let me know.

Stuck in demo mode on GE jvm1850 microwave tried unplugging, tried power level and zero at same time, tried holding clear, holding help, tried everything i have read so far but they seem to all be for...

A hard reset would be the first thing I'd recommend, but unplug it for about 2 minutes, plug it back in, and watch to see what it does.

Wait at least 60 seconds after powering it up to see if an "F3" code comes up.

You can download GE owner's manuals and installation instructions here. See what it says about a demo mode.

Otherwise, I would suspect a shorting keypad.

If you need more help, we can let you know what your options and costs would be and send you other helpful info.

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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Our panasonic microwave keeps shorting out

It sounds like the power relay on the main control is shutting down. To fix this problem you would need to replace the control (Mother board). Before doing that the magnetron (heat element) should be tested to make sure that it is not what caused the relay to fail.

If you send me your model number I can try and get a ball part price on the parts you need.

GE Microwave shuts off after running 3 seconds

It is a loose or bad magnetron emitting electrical interference that disrupts the control unit.

When you move the circuit board away from the magnetron or take the cover off, the interference is weakened, and the control unit works fine.

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 within the mag warranty, G.E. should send you the magnetron to do it yourself. Call them at 888-239-6832 with your model, serial, and manufacturing date.

If nothing else, you can save about $50-75 if you remove it from the wall and take it to a GE-authorized servicer.

open by unscrewing screws on back and along left side bottom. this lets you swing up the cabinet showing the electrics. the red power line going to the timer is held in place by a metal wire holder that is riveted to the base. wire has a white sleeve between its insulation and the metal wire holder. slide wire and sleeve out to the side of the holder. slide sleeve to side along wire, revealing fuse. need a solder iron and an electronic parts store to get replacement fuse and solder it in. reassemble.

the fuse is a resistor that blows when unit is getting hot. use lower resistance fuse or just hardwire the power line straight through, no fuse, but watch for overheating (not likely) and maybe use breaker outlet

Stops cooking

I had the same problem, but seem to have fixed it last week. Thank goodness, because with 2 little kids, I really need the microwave.
My January '05 model JVM1653 would intermittently have a flickering display then reset itself after about 3 seconds into a full power heating cycle (it was still ok on reduced power). I don't know what the problem was for sure, but protecting the front panel circuit board from radiation seemed to do the trick.
I put a sheet of aluminum foil in a ziplok bag (I used the gallon size, but the 1 qt size would probably do just fine), taped a "twistum" tie with the plastic stripped off the ends of the wire to one corner of the aluminum sheet, and then sealed up the bag and put a piece of tape on the corner of the bag where the wire was hanging out. With the front panel tilted out, I attached the other bare end of the tie to the green ground wire screw. I then "stuffed the ziploc into the open behind the panel while trying to keep the circuit board as shielded as possible. I carefully closed up the front panel, making sure i didn't get the ziplok punctured by the circuit board stuff.
So far so good!!!

In the middle of cooking frozen dinner, instant death..

We have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: If the fuse blows a few seconds after you hit START, then it's likely that you have an overheating / shorting high-voltage transformer. Try this: Let the oven set unplugged for about an hour to cool completely. Then cook for a minute at the lowest power level. If it runs any longer than it has been, it's probably the high voltage transformer, which is no longer available, but will run about $95 if you can find new old stock. If the fuse blows as soon as you hit START, then it's likely that you have a shorted high-voltage capacitor (#RC-QZA211WRE0) which runs about $25.

Shorting out

Sounds like the units main elecrtonic control board. You can contact your local parts house for the parts as they should have them or call GE at the #b in the owners manual. I must advise you that there is a very hi voltage inside these microwaves so you must have some know how on working on large appliace and if not PLEASE seek a pro to assit you in this repair. Good Luck
