The fan on my microwave keeps coming on by itself

Could be in one of the micro switches for the door or in the board. Most commonly one of the switches though.

proceed with common sense, clearly, and logically.and fix it .God bless you
Microwave overheats and keeps turning off All microwaves have some sort of a cooling fan to help keep the magnetron and controls at a tolerable level. Most OTR models will usually use the vent motor for the cooling fan also. Countertop units have a small fan behind the control panel somewhere. Either way, if the cooling fan is not working and heat builds up, it is going to open a thermostat. On some makes, this thermostat might re-set itself as soon as the temperature cools down. Other makes, you will have to replace the thermostat or fuse.
If this is your microwave oven repair problem, you will need to check the operation of the fan. Below in the component testing chart, you will see how to test the fan. Also, if possible, make sure the fan is not obstructed somehow and not turning. Also check your fan relay at your control board for voltage, if no voltage, replace control board. This fan should come on at the same time any cooking starts.

An SE error on a Samsung microwave means you have a shorted membrane keypad.
If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

Please reply back with your full model number from the tag in or on the unit so we can help you with an estimate or free DIY tips.

I advise customers to always turn on the hood vent exhaust fan whenever cooking on the stove top to help keep grease, steam, and heat out of the controls of the microwave.

The heat is affecting (and may have damaged) your membrane keypad.

In some cases, this can lead to the microwave's coming on by itself, which can lead to a fire.

So if it does anything odd or comes on by itself (even once!) be sure to keep it unplugged or keep the door open when not in use.

And as with any microwave oven, never leave it running unattended.

Once you know your keypad is damaged (if it fails again) then it will have to be replaced.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

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

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.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

But please note that for some GE models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

Either way, we can let you know what your options and costs would be and send you other helpful info.

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.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

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