Remove the outer cover,be careful and take 2 screwdrivers and discharge the hi voltage capacitor its about 4" X 2" and oval in shape and usually silver colored,then remove the chemical 15 or 20 amp fuse it has 2 silver ends and a white body,check this with an ohmmeter good will be near 0 ohms,if open replace and plug in and start it,if it blows the new fuse, then again discharge the capacitor and take an ohmmeter reading of the cap, it will show resistance and gradually go up in resistance if good, if bad it will show near 0 or very low ohms,then check the hi voltage diode,it will show near infinity in one direction,then reverse the ohmmeter leads and it will show lower resistance in the other direction,if these check o.k. it possibly could be the magnetron tube

Replacement or fix


just replaced our 6 year old Thermador MBBS ($750) with a GE JES2051SNSS from Home Depot ($179). The bottom guide piece from the Thermador bolted right on the bottom of the GE and positioned the new unit so the front trim piece fit perfectly.

The problem is the magnetron, "heart of the microwave oven" or the inverter board if 7 years old or less.

I have a 2 year old ge micrwave. I shut the breaker off to change a furnace filter and now the microwave is not working and just says to "press clock". When I press the clock button, nothing...


If you press clock and nothing happens your keypad has shorted out and needs to be replaced. Try to unplug the unit one more time and try to turn the unit on again. If you have the same problem replace the control panel.

Kenmore elite microwave touch screen stopped working


Same thing happened to us. We just came back from Sears, where we bought another. Just for giggles, my wife suggested unplugging the old one and plugging it back in again. It works now. New one's going back to the store.

GEJE2160 Stop Working


It probably blew the main power fuse in side the oven. This may have happen because of a failure in the microwave or a line voltage surge or what ever. Repalce the fuse and see if it work. be sure to unplug it before doing this, If this does not fix it then you have a failure in the oven some were.
good luck

Microwave appears to work fine but will not heat at all.


Sounds like the thermal protector on the mag tube quit. It may have gotten too hot and opened up. That is the lesser of all the evils that can happen to a Microwave.
