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)
