does it have 2 white buttons on the door frame that get pushed in when the door is closed?
if it does one will have 4 wires & one will have 2 wires. the one with 2 wires is the memory protect switch. make sure that this switch is working.
try removing one of the wires off the white switch with 2 wires and try the adjust buttons again. (remove the wire with the pin turned off)
