We have the full service manual for this model and have uploaded it to our site here to help you.

You will need the
free Acrobat Reader to view or print it in case you don't have it.

The parts I would suspect most are the internal fuse, the magnetron TCO (thermal cutout) or the oven cavity TCO.

To check or replace the latter, you'll need to remove the oven from the wall and remove the cover.

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.

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

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

My Kenmore elite microwave model 401.88523011 has lost power. The electrical outlet still has power to it. Is there an internal fuse or circuit breaker that may be causing the power outage?


Your microwave has an internal fuse. Usually 10 to 20 amp. You can pick some up at home depot or radio shack. Make sure you get the same amps and volts as the original fuse. Will be printed on your microwave some where usually. And if its one that is part of a double oven deal make sure that you check you're circuit breakers for the kitchen. Good luck.

Used the microwave last night. Later I noticed no light display for the clock. Come to find out microwave lost all power. Model number smh9207st


If there are no fuses or circuit breakers, the unit could be down and out. Check you power box for any tripped breakers.

Built-in Sharp Carousel II Microwave Convection Oven died.


There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.

Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.

Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.

Hope this has helped a little. Thanks for using Fixya!

Our Emerson microwave died and I bought a new one. Plugged it into the same socket and it immediately shorted out and died. After the new microwave died I plugged a blender into the same receptacle and it...


I believe you have a bad circuit breaker or fuse. If you have a delay fuse contrilling this circuit, that would explain the spotty availability of power to the outlet. Also, a faulty circuit breaker can operate in an irregular way, as you describe.
A microwave oven requires a lot of power, relatively speaking. If your microwave is a 1200 watt model, for example it draws 12 amps of power, which could well be almost all of the power available at that outlet, providing that other appliances were not also drawing power from that circuit at the same time.
I can assist you further, but if this information is all you need to proceed that is fine too. Get back if you need more assistance.

MY KENMORE 1000 WATT LITERALLY WORKED FINE ONE MINUTE THEN NOTHING THE NEXT. I HAVE NO IDEA WHAT HAPPENED.


Most likely the circuit breaker tripped or the fuse blew. A 1000 watt microwave is using 2/3 of the power available on a typical household circuit of 1500 watts. If anything else is plugged into that circuit u can have a problem. Just reset the breaker or replace the fuse and u will be up and running. if it happens alot you should consider a dedicated circuit for your microwave only.

How can I get the power to come on my Sharp microwave?


The problem may be an electrical one. Microwave ovens require a lot of power. Often, they use most of the power available to the circuit they are plugged in to. If there is not enough power in the circuit to feed the microwave and whatever else is plugged into that same circuit the fuse will blow or the circuit breaker will kick off.

Go to your electcical box, and check the breakers or the fuses. If one of the breakers has kicked, reset it by pushing it all the way off and then back on. If the fuse is blown, unscrew it and screw in a new one of the same amperage.

good luck. please rate my answer. thanks

ALL POWER LOST


I am not sure I can solve your problem or perhaps you have already solved your problem. My thought is "are you sure your circuit Breakers are OK"??? In order to re-set a tripped circuit breaker you have to first turn them all the way off, then re-set them to 'on'. If you did not do that they probably did not re-set.

Assuming you did that correctly then I would have to suggest you contact prototech@usa.net. He/they might know of a internal fuse or other problem the may help you. Good luck.

No power to Panasonic NN-S252 microwave oven

No power from Whirlpool.


IF YOU HAVE THE MICRWAVE PLUGGED IN AND THE CIRCUIT BREAKER TRIPS IMMEDIATELY WHEN SET,
CHECK THE DOOR HOOKS THAT TRIP THE DOOR SWITCHES. BOTH SHOULD BE SPRING LOADED. THERE SHOULD BE TWO HOOKS ON THE DOOR. IF O.K., CHECK THE DOOR SWITCHES. THERE ARE AT LEAST THREE. IF ONE OF THEM IS SHORTED CLOSED,
THE MONITOR SWITCH WILL CAUSE A DEAD SHORT ACROSS THE FUSE. THE FUSE MAY BE HOLDING BETTER THAN YOUR CIRCUIT BREAKER.
