You may have a stuck relay on the control board which is causing something to come on when it shouldn't. Or it may be a door switch or door switch mount issue.

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.

Another thing would be to put a cup of cold water inside for a minute to make sure it's not cooking.

But either way, I think it's best to just unplug it and not use it until it is repaired, since it can damage the oven or pose a fire hazard.

We have critical safety & disassembly info (including a how-to video) at our site, linked here.

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

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

We repair these control panels for customers nationwide with our guaranteed $39.95 service.

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

Microwave fan goes on by itself without burners being on or used

It sounds like you understand that the exhaust fan is SUPPOSED TO come on when the microwave oven gets hot when exposed to the heat of the range below it, since you mentioned that no burners are turned on. So in that case, I'm pretty sure that you have a bad fan thermostat. It's usually located behind the control panel on the bottom (inside bottom) of the microwave floor.

What do I do when the vent won't turn off?

unplug it for 12 hours or more and try again. Failing that the button or circuit for it may be broken, also make sure nothing is blocking the vent or nothing in the vent assembly is damaged. if you are opening the microwave make sure you know what you are doing of get a pro to do it for you. get an estimate and compare that to the price of a new one. Especially if the microwave is old or cheap.

The GE Spacemaker Microwave Oven model JVM1540 makes a loud fan noise whenyou turn it on. Sounds like the exhast fan but it not?

It sounds like from the description when it is running the noise comes from the magnetron, some microwaves are louder than others, but this could be an early sign the magnetron is going.

Auto fan won't turn off. How do I turn it off? It keeps saying it will go off when it does not detect heat. But nothing is on.

Sounds like the thermostat went bad. Try unplugging it for several minutes, if that doesn't work replace the thermostat.

Making a sound (I think from the fan) when operating

If it is only when he exhaust fan is on, something is in the fan. Remove the grill and investigate. If it is from the Magnatron fan you will have to remove the front panel.

My microwave stops goes dead after running for 2 minutes

It may be that the magnetron is overheating. The main causes:

- blocked air vents
- blocked air outlet or duct (if an over the range type)
- clogged grease filters needing to be cleaned
- clogged charcoal filter needing to be replaced
- failed internal cooling fan
- failing magnetron

Depending on the model, it may have a thermostat on the magnetron so that the power is killed if it overheats, then it comes back on when it cools down.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

Please listen to that and compare it to yours. You may hear that your cooling fan is not running.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the turntable and stirrer won't work, and magnetron will soon be destroyed.

If instead the microwave starts microwaving then it scrambles and then comes back up as if someone unplugged it for a couple of seconds and you can set the clock and start again, then you have a magnetron that is leaky.

Once you listen to that and check your vents, filters, etc., let us know what you find so we can take it from there.

Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, and your detailed symptoms, as well as the results of these recommended checks.

How long does it stay off? 30 to 60 minutes?? Sounds like the cooling fan is not working or air vents on the unit are blocked.... I saw one unit years ago with this complaint that when the customer turned on the MWO, the fan came on and pulled a curtain covering the pantry up to it, blocking the air flow and causing it to overheat and shut off....
