Well, felt like playing mechanic & I dug into the insides of the adt to retrieve the bad motor. Before cutting it loose from the wiring, I check to make sure that it was indeed getting power with a volt meter -> yep, motor is toast!
What a bugger fishing that out! Had to bend the metal cab to make room, likely be a great deal of aggravation getting the holes to line up again. :crazy: Only a few mm between the two motors, very tight area down there.
Now to find a replacement motor. What it says:
RS-385SH
RD445522
CHINA
Got an email from Vario Germany a few minutes ago that the parts on their way already, great service!
