Air Step Diagram

[brad barton]

Larry,

This is probably no help, but is there a chance that another switch or contact is placed somewhere else in or around the door, in the crack or hinge or under the step? I have at least three contact switches in the inside corner of the door, with other valves and solenoids around the step. If you're sure you've found them all, please disregard.

Subject: [WanderlodgeForum] Air Step Diagram

I have been fighting my air step for a year now. All the diagrams
posted on the forums appear to be for earlier birds and do not match
my wiring. My blue box does not have any diagrams that include the air
step.
I have two issues now. The extending cycle works but the retraction
cycle does not work. The solenoid valve is not retracting when power
is applied. That I can fix or replace easily.
The real problem is that no power is coming through the retraction
circuit under any combination of switches and door condition.

I can not trace the wires after they enter the front panel. The air
handlers are in the way.
Any suggestions? Anyone have a current wire diagram?
