Remove the 4mm spacers and open and close
the door 2 or 3 times to allow the parts to work
together.
Set a Multimeter Resistance [ Ω ] and connect
the meter to Fuse F4 and Tag 7 on the Relay
PCB Board.
Check that microswitches SW2 and SW3 are in the CLOSED [ON] position and
the Multimeter reads a minimal resistance.
If the meter reads Open Circuit, remove the 2mm spacers and repeat steps 1-4
