Re: fan vent door not working

First of all, if it's less than a year old, it will be under warranty and you should contact Samsung to cover the service. You can try the number in your manual or try

There is a drive motor that opens and closes the vent fan door. It or an associated switch may have failed.

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa:

Mmv5165bas vent fan will not stop running

Check to see if there's a relay providing power to the fan. If there is, the contacts might be sticking in the closed position. Assuming that this is an over-the-range unit, disconnecting the vent fan completely might not be a good idea as heat/steam from foods cooking on the range would more likely damage the microwave.

No heat, does not cook

Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 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.
Q - My microwave is running and sounds like it is working but will not heat up anything.
A - 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.
 Q - My microwave went dead when I opened the door ( same problem as closed the door ).
A - This often is a stuck or faulty door switch and it has blown the interior microwave fuse.
Q - My microwave is completely dead.
A - House fuse has blown or interior fuse inside the microwave has blown ( usually a part inside the microwave makes this fuse blow ) Sometimes a bad fuse holder inside the microwave cannot hold the fuse tight enough and the fuse will blow as well. 
Q - The fan in my microwave oven is not running will this hurt my microwave?
A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace.
Q - My microwave blows the fuse inside itself as soon as I push the start button.
A - Usually a shorted high voltage capacitor...see components section.

GE JVM1870SF02 - not heating up anything!!

I had the same problem with mine, and discovered, somehow, that when I manually turned on the "vent fan", the microwave worked fine. A bit of a pain, but it heated up the food when it hadn't been prior to the vent fan being on. Can't understand why it solved it, but it's been working like that for about a year now. When I forget to turn on the vent fan though, the food is just as cold as when I put it in.

Emerson MW8119SB microwave wont stop running with door closed

It should have a one-year warranty on parts and labor.

I'd call Emerson at 1-800-695-0098 to find your nearest authorized service center to have it fixed free.

It's probably a bad door switch or door switch mount.

MIcrowave oven stopped heating - Whirlpool MH6150XMS

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa:

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, which is very helpful when troubleshooting.

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help
