Woops, very wrong...sorry
Model: MMV4205BAS

There may be a limit switch such as what's on the ge microwave that is in either the line or nuetral circuit that will,when blown, open circuit to everything including control board. I know that this limit switch is heat sensitive. As to whether it's current sensitive, I'm not sure. I could not find a diagram, maybe AJ has something. Check your fuses and all your limit links that are in either the line or nuetral circuit.

Thanks, good info on tracking...  The fuses are good and only have one open 2 limits on the base behind control panel...one closed one open am assuming the one open is for fan and will close at higher temp.
