Question about Whirlpool MH1150XMQ Microwave Oven

1 Answer

No power to unit

Everything on the display lights up. When I set a cook time. The unit counts down, but nothing else happens. The problem did not start until I tried to replace the light under the unit. It would flicker, I tried to change it. I took off the bottom panel, noticed the bulb was loose, tightened it, then it blew up. After that only the control panel works, but nothing else. I need some help. I've only had the unit 5 yrs and it gets below normal use. Please help me to salvage this unit.

Re: No power to unit

I would first suggest that the door switches and door switch mounts be checked, but one of the problems is almost certainly trouble on the control panel, which we regularly repair nationwide for $39.95 postpaid.

The light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This often can affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on. Other trouble can occur as well.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement,
disassembly information and info on our repair service at our site, linked here on Fixya:

Please write back with more details if you need further help.

My microwave stopped working you can input time but when you push start nothing happens it has power and everything just will not start its like the start button does not work

Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

Sharp Carousel R530BK microwave won't cook unless light pressure is kept on the door button.

There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

Have ge model je1860 turns on but when you hit cook nothing happens is it the turn table motor. i don't want to do trial and error on parts.naturally the fuse is good

I'll presume you can program it ( set the length of time you want to cook)
Does the timer count down?
Does the turntable ( if you have one) turn?
If everything else seems to work properly and it just doesn't cook more then likely the magnetron is bad

I would replace the door switches and set up the door gap to 1/8" just enough to alow for a little play.
Setting the door square is acheived by slackening the lower door hinge and re tightening it when the door is square.
Hope that helps.

The timer counts down but the microwave doesnt turn on.

I have a FNCB115GC Microwave problem. The microwave has a icon on the left hand side of the panel that looks like a opened book on a stand with lines on top. This is best that I can descibe it. The microwave turntable does not move or the microwave does to come on but the light comes on and the timer will count down. I have cleared the microwave and unplugged it with no results. Please help. Thanks in advance.

We changed the cooktop bulb and now nothing works. When you push the light button the light inside the microwave turns on. If you set the cook time the time counts down but nothing runs.

Check the door interlock switches. They will keep the unit from starting but you will have power everywhere else. If this is helpful, Please leave positive feedback. Thanks, SnugglePants

All the lights and features work, but no heat. Will not cook.

9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section. Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay..... Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.

Does not cook - time counts down extremely fast

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Then let us know if the hard reset does not fix it.
and please reply back with your brand and model number so we can help you.
