Sounds like you might have a few issues or possibly a bad board. Did you replace the whole door assembly or swapped everything to a new outer door? Is this the big door with the transfer roller or the fuser door?

I would double check the wiring making sure nothing is pinched causing a short. The exit sensors will fail due to heat from the fuser and usually start out flaky. Replace the sensor.

The powering off is a bit odd though. Let me think about it a bit and I'll get back to you...

The power off thing..... the Grey arm that the door opens with that pivots down when open, is connected to a power cut off switch for the fuser. It is under the front cover. It can short it out. I have not had a lot of photo cells go bad in those but you never know.
