No Power Whirlpool MH7140XF

The door on our microwave was slammed shut and now no power. The circuit breaker was tripped. I reset it and still no power. I checked and I do have power to the wall plug. Any ideas would be appreciated. Thanks.

    It does not light up at all. I found a small gray fuse behind the control panel and will go buy a new one tomorrow. I am guessing there is something else wrong, like you say maybe a door switch. If it is something like a door switch is it recommended to pay someone to fix it, or cheaper to buy a new one? Thanks for replying.

    Have the exact same problem.  Door was slammed shut, circuit breaker needed to be reset and still no power.  Nothing at all appears on the readout,  including time.  If it was the door open or shut sensor, shouldn't the time still appear since it appears weather the oven is open or closed?

    Same model, same problem. No power to microwave. Door might have been slammed. There is definitely power to the plug and no display or power of any kind to the microwave. I did not see a fuse on the exploded view of the parts for the control panel. How do I get to the fuse? Has the fuse been confirmed as a fix for this problem? Also the comment that the other person's microwave might have been "fried". What does that entail? Would you need a new control panel. This thing was a pain to install and matches my other appliances. I would prefer to repair it if the part is not insanely expensive.

Does it not light up at all? A microwave has a fuse on it. Probably accessible from the back panel. if not you would need to disassemble it. Most likely cause of this is slamming the door broke one of the safety switches the door has so the microwave knows when the door is open. And it shorted against something when it broke. It might have simply blew the fuse but then again you might have fried it.

    its always cheaper to do it yourself if you are competent. if you pay someone else you might as well buy a new microwave. I got a medium capacity one at sears for only $100 and it's energy star compliant. But just replace the fuse for now and see what happens.

Samsung Over-The-Range Microwave Oven just went out, wont come on at all.


Hello Terrell,

If "wont come on at all" means no light when door is open, no clock, nothing, then assume complete loss of power to that circuit.
These are often powered by an isolated circuit with its own breaker. The first place to look is your power distribution panel and see if you can find a tripped breaker.
If yes, then reset the breaker and see if the microwave has lights, clock, etc.
If no breakers are tripped, the actual microwave plug is often in a cabinet above the microwave. Sometimes, these may get pulled out while moving items in and out of the cabinet, so check that too.
If unsuccessful, microwaves also include an internal line and/or thermal fuse which fail due to overloading. Also, the control panel can go bad or become unplugged from slamming the door, etc.
If you do have lights, clock etc., then a faulty door latch will prevent operation of the microwave generator.

Unfortunately, will need additional information to properly identify the potential.
I hope this helps.

Whirlpool microwave GH7145XFseems to have shorted out. Is there a circuit breaker somewhere on the oven itself that can be reset? History: Trying to turn off the oven light when the door was open, I...


There should be a line fuse inside, and a less likely culprit would be the oven cavity thermostat.

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.

mini_manual_behind_grille_small.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here (just enter your full model number without dashes).

Accessing the oven cavity thermostat for testing and possible replacement will require you to remove the oven from the wall and take off the outer 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 Whirlpool owner's manuals and installation instructions here.

If both of those components are bad, it may be a damaged control circuit board.

We can repair that for $39.95 in most cases, or you can buy a new "microcomputer" circuit board (part number 8169379) here for $146.66.

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.

GE Spacemaker Microwave JVM1441 BH04 tripping circuit breaker


your power transformer for the magnetron could have a shorted primary power winding,the door safety interlock switch could be mis-adjusted,this normally blows the internal unit fuse,a shorted high voltage capacitor,or diode,a bare wire inside the unit,more than the microwave on that circuit or a weak circuit breaker in the house power panel

No electricity Clock is off nothing works


Plug something else into the outlet and see if the device works if it doesn't then reset the breakers. If the other device does work then the microwave is bad and needs replacement.

Loss of power to Whirlpool over the stove AccuWave GH5184XPS-4. Checked circuit breaker and GFI -all OK. No other electrical problems known.


Remove unit and check trip/reset switch on unit. Double check GFCI receptacle with plug tester with GFCI test button.

Microwave went dead


Hi

If your microwave oven doesn't seem to work at all, check these: Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.


Please do rate the solution as FixYa and revert for further assistance.

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.
