It may have gotten steam into the controls despite the fact that you had the hood / exhaust vent fan on, which is proper procedure.

The best bet is to either let it set unplugged for a day or two in hopes it will dry out, or unplug it, remove the control panel and dry it out with a hair dryer (but not too close - don't want to melt anything).

At our site (below), we now have a video available showing how to remove a typical control panel assembly in under 5 minutes.

If you have had it unplugged for a while, it may have dried out enough to work.

If the fan still stays on all the time, the hood fan thermostat may have opened up, too.

If all this fails, it may need repair on the control panel assembly.

Please feel free to contact me directly if you need more help.

We do that for customers nationwide for $39.95 in most case, but we also offer loads of free do-it-yourself tips and advice.

We're happy to help and we appreciate your thoughtful rating of our answer.

The vent will turn on randomly and not turn off!


Most over the range microwaves have a heat safety system built into them. If for instance you are cooking on the stove top for a long period of time on the burner directly under the micro control panel and the control panel get too hot, a thermostat in the microwave will automatically turn on the vent fan to help keep the control panel cooled off. My guess is that the safety thermostat (usually right behind the bottom of the control panel) may be going bad and needs replaced.

Microwave won't work, I was cooking on the stove and the fan came on and then everything went out on the microwave suddenly


There is a thermostat which detects when the temperature from the cooktop is too high, and it makes the hood vent exhaust fan come on to cool it to protect the controller.

That's I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

Assuming the wall outlet is good, 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.

If it's still dead, another thermostat may be blown,or the fuse.

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.

Usually the fuse and magnetron thermostat will be accessible for testing behind the controller.

If those are good, then it may be a bad oven cavity thermostat, and checking that will require you to remove the oven from the wall and take off the outer cover.

Behind the controls in many microwaves is a technical sheet, which helps in locating and testing components.

Keypad not working after boiling water below


Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

And I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

If it does not dry out over time, it may need to be manually dried or blown out.

Otherwise, the keypad may be damaged or worn out, or control unit may be damaged.

Microwave popped and now does not heat


Okay, first we need to separate the situations. You were boiling water on the stove and had the range hood fan running to **** up the steam. Then you put something in the microwave to heat and you heard a pop and then zip-o.

The water on the stove has nothing to do with the situation, the fan you turn on is not part of the microwave, so it has nothing to do with the microwave.

The pop you heard and then the humming suggests the magnetron failed. You said you found a blow fuse and replaced it and still nothing, right? The magnetron is the most likely culprit...I would think it is safe to say that the magnetron shorted and drew enough current to blow the fuse.

Replace the magnetron and if that doesn't work, let me know here. Good Luck!

I have an over the stove kitchenaid microwave w exhaust hood. About 1/2 hour after boiling water on my stove, my microwave comes on. I have unplugged the microwave-----any ideas?


The issue is probably your exhaust fan on your microwave comes on automatically when it detects a certain temperature. Mine does this as well but will turn off automatically after temperature goes down.

Microwave turned off


I always suggest that the hood / exhaust fan be on whenever you're cooking on the stove top. This helps keep grease and steam out of the controls.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

Otherwise, you may have a bad controller, which we may be able to repair for you.

I would say the oven thermostat has shorted or you may have a stuck relay on the control panel.

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

GE spacemaker Profile XL1800 vent fan will not shut off


It may be a bad door switch, a loose door switch mount, or a problem on the control panel, such as a sticky relay.

I would suspect a sticky relay first, but the door switches should be checked.

Fan stopped working in JVM1533BD microwave


I assume you're talking about the hood fan which ventilates the cook top and blows air through the grille across the top. If so, it's okay to use the microwave with that not working, but if you boil something on the stove, an external fan is definitely needed to keep mositure from going up into the microwave controls. If the cooling fan INSIDE the microwave (behind the keypad) is not working, then you do NOT want to run it unit it is fixed.
