SOURCE: GE Dual Wave II microwave oven blowing fuse

It sounds like a shorted high voltage capacitor, a fairly cheap fix. But if it's good, I would suspect the high voltage transformer.

Here are some links you or a friend can use for test help, but read the safety warnings first:

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

You have a failing keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

SOURCE: my microwave panel is not working.

Sometimes if the door switches are faulty then the touch panel may not respond. There are usually 3 switches, and I'd recommend if one if faulty replacing all of them as a set. Otherwise it may be a Control Panel fault.

SOURCE: GE jvm2070 microwave touch panel does not work,

The only thing you can do is re set the main board, unplug the unit fot a minimum of 1 hour then try it again, if not you main board is out (this is caused by replacing the light bulbs with out unplugging the micro most of the time) If it is not in warranty I would advise to replace rether than repair, you get an average of 7 years out of them these days. Good luck

No power to Samsung SMH7159 Microwave


There is more than one fuse. Look for a second one.

Panosonic Microwave convection Model NN-8501V Touchpad appears dead


The unit has a fuse in the power board, but when the fuse is gone it does not even start up. If it starts it is not the fuse.

Look rather a problem with a faulty touchpad, or the magnetron that is not working and need to be changed.

Check also the door sensor.

Neither the oven's display nor the oven operate why?


Sounds like you have a blown fuse. Sounds also like it is an over the range unit and you definitely would need help if you have to take it down to work on. Depending on the brand and model, the fuse should be behind the touch panel somewhere. If you put in the brand and model with your question, it did not come through, so I cannot be more specific as to how to get into where the fuse might be located.

It has no power. nothing lights up or works. I tried different plug. still nothing


Joseph,
You probably have a blown fuse. Sometimes you can take the control panel loose and access the fuse from there, but you may have to take the microwave down from the cabinet and take the cover off to find your fuse. If you have to take it down you will need another person to help you as it is a two person job to do that safely. If you can take the control panel off, make sure that you unplug your microwave first. Also, be careful about touching any wires coming from the magnetron or the capacitor because they can carry very high levels of voltage. Hope this helps!

I shorted out the counter lights on my frigidair microwave. The microwave works but not the lights. I've replaced the bulbs. What next?


The metal base may have fused together from electrical arcing when the old bulb was removed. The entire bulb receptacle (socket) will have to replaced. If you cannot do that yourself, the cost would be excessive. Just live without the light as long as the microwave gets the job done.

Emerson Microwave model #MW8111SS fuse blown


You also may want to take a close look at the control panel. I found a grouping of 3 resistors at approximately center of the board that were cut on one end. Probably a design change poorly done. Somehow, just out of the blue, those loose ends touched and blew that fuse. Removed resistors........problem solved.

My ge microwave model jes1384sf stopped working and sure that the power is going to the microwave, But clock, timer and contol panel etc. nothing turns on. Is there anything can be done to find out what...


You have a power fuse inside of the panel that supplies AC power to the panel as well as the klystron tube. This is generally a slow blow 15 amp Buss fuse. Since these fuses deteriorate over time and they are sized to just hold the requested amps (15) to prevent a possible fire. You will have to take the Panel apart and find the fuse, but be sure you flip the breakers as the panel has a High Voltage power section with large capacitors that can produce a nasty shock. Before touching any thing with the breaker power off, short the capacitors to ground to discharge them, then pull and replace the Buss fuse.

Same problem - panel out - no light


Open and remove outside panel. Inside next to the plug in (power supply) there will be a glass fuse. Look inside the fuse and see if you can see a thin metal wire running across the entire glass tube. If it does not touch end-to-end, then it should be replaced.
If the fuse is good, then you may have faulty power supply or even bad circuit board.

No display on microwave touchpad for ge Model JKP62G


The GE JKP62G Microwave / Oven combination has an internal fuse behind the control panel for the microwave. The oven will operate but the microwave will be totally dead (no light, no clock). Turn off the breaker for the oven at the fuse box (30 Amp double breaker). In order to replace the fuse you will have to open the door to the microwave, remove the two screws (Torx) from the front control panel (located on the left edge of the control panel), wiggle the panel to the left (there are two metal tabs that stick into the metal frame of the microwave on the right of the panel) and then tilt the panel down from the top. There is a metal bracket that holds the control panel to the microwave at the bottom (don't remove it). Look towards the top of the microwave inside the area behind the control panel and you will see a 15 Amp screw in fuse. Replace the fuse and that should fix your problem.
