  1. Is it totally dead, no lights at all?
  2. Did it fail while cooking or you found it like that?

1. yes totally dead
2. The fan was running and I opened the door and it went dead. I did not notice at first.

Okay, so the monitor switch and fuse will likely need to be replaced. Are you comfortable with electricity and wiring?

I do not have a schematic of it. Do you?

The small 4 way control broke once before. It is only plastic and was a doozy replacing

Okay, so the grille from above the door will need to be removed (screws on the top). Once it is removed, there is a screw at the top of the control panel that will need to come out. Once it is removed, the panel will lift up and hinge down. Please allow me just a few minutes to prepare some information for you, thank you!
