Mpc 5501 front cover open

[ash_572]

I changed both front door switches with no joy.

In input check 5803-38 interlock release detection 1 changes signal but 5803-39 interlock release detection 2 does not change signal. Right side door signal changes fine.

Very strange random problem I have here. Sounds like a board problem

I think that there is a third switch for the front door. Item number 19 on the attached.

It looks like it is mounted on the upper right of the front frame. With the way the parts catalogs are, it could be it could actually be on the lower left of the rear frame in which case it is the main switch.

I downloaded the parts finder and by rotating the view it is the power switch.
