My unit has only one fan I have attached a picture.  This microwave has a trim kit it is not the one with the exhaust fan above a stove.
The one fan that it has still works, I see the Magnatron but do not see a fan on it.

Nice picture.  If you have an ammeter, clamp it around the black or white power cord wire.  Put a glass of water in it and turn it on high for a few minutes.  You should get a reading of about 15 amps.  If you don't have an ammeter, listen for the magnetron to kick in.  It's a slight buzz you hear about a half second after you start the microwave. If the amperage drops out or the mag quits buzzing, immediately unplugged the microwave and discharge the hv capacitor.  Check the thermal limit mounted on top of the magnetron, it should have continuity.  If it doesn't have continuity, your magnetron is overheating for some reason.

The fan for the magnetron is that big thing to the right of it with a motor attached to it and directly behind that is the holes I was talkin about. The black klixon on top of the mag is the high limit. It might be weak and tripping after 2 minutes. I doubt it though. The thing looks pretty clean to me. Is that fan blowing pretty strong? That type of fan motor is a 3000 rpm so it should kick up some air in there.

Watch out for the high voltage.
Even when the microwave is unplugged the capacitor can still store high voltage in it.

 

Stove no longer heats?
