GAL has 2 sizes for the cam nylons. Make sure you have both sizes before you take the assembly apart

so let me get the correct picture...Your door close relay drops out before your door close limit breaks? Are you losing the normally closed contact on the DO relay? Or the door stops before the DCL breaks. The resistor for the close speed is very fragile with thin wire and breaks easily. Possibly it opens up when it heats up.

Watch the Door Close bit in internal memory, during the close cycle. Compare it to the DLK LED on the processor board.
IF the DC bit goes low, before the DLK led lights up, then the processor is ceasing the close function, probably because that's the way it interprets the inputs it's receiving, one of which, (one of many), is the Door Close Limit.
On the other hand, if the DC bit stays high, yet the DKL led stays low, then the processor still wants to close the doors, but it's intentions aren't amking it to the DC coil, and in between there could be an issue.
(Hope that doesn't sound too vague)
