Touch pad doesn't work
Your touch pad is connected to your board with a ribbon wire, it has probably come loose. Unplug the unit and remove the face plate. Pull it back and you will see the wire, it looks like a ribbon, push it in tight, replace the face plate and it should work properly. I see this happen all the time.
Maytag CMV1000BAW microwave doesn't heat
Probably a bad mag, if the transformer goes bad it will draw a lot of amps and blow the fuse. If a mag shorts it just makes a more pronounced hum. Same with the rectifier. If you Ohm out the rectifier it should show open both ways as it is a really high resistance and the only way it would make a louder hum is if it shouts. so If it looks open it is probably OK, and probably bad mag. .
