Just converted a 19" machine to 044 and it is now looking for a closure on door "L" and don't see any other door switch wiring in the harness. It is looking for closure of MBOL where M = main, B = Bill, O = not sure what this is but have it currently jumpered so it is showing closed, and L = don't know what this is. Any ideas? have wiring diagram for 044 mother board to see if it identifies another switch? Machine was working fine as an 039. Have converted other machines and have only had to deal with doors closures for M & B.
