Mbbs 01 thermador micro oven: timer counts down, lights go on, but no heat, no fan and turntable does not turn. is it a fuse?

Key clue is table does not move---All microwaves with a table have a lever switch that is engaged when door closes--only can get at from inside the unit----it prevents the unit from operation if door not closed.

What happens from closing door a lot is the switch with a lever arm can come loose or even if snapped into a plastic holder break out of the holder.

IF this it is not too expensive a repair.
