There are 2 fuses inside the cabinet. One is for the clock and turntable. The other is for the high voltage transformer and the microwave module. If this fuse is blown either the transformer is shorted or the module has failed to cause the fuse to blow. Parts and Labor can get close to the cost of a new one, so get an estimate so you can have information to make your decision

Typically there is a metal mounting plate screwed to the wall and when you take the screws out of the cabinet above it it will tilt forward toward you and then you have to lift it off of some metal tabs that are on the bottom of that mounting plate. Lift up and pull away from the wall and let the cord pull out of the hole in the bottom of the cabinet. Good luck. I usually do that by myself and hook one arm under it and lift it up, but probably better with two people.

Sounds like the on switch for the fan is fused in the on position. You may need to replace the switch

Paul, if you look on top of the microwave before you install it you will see where the fan is located at the back edge. There should be 2-4 screws that hold it in place. Remove the screws and pull the fan up and out of the microwave and rotate the unit 90 degrees towards the front of the microwave and put it back in and replace the screws. That should be all that you have to do to get it to vent out the front.
