Went out to the rig this morning and opened the door and the steps opened fine. When finished with jobs inside I exited and closed the door.....and the steps wouldn't retract. They worked fine all last weekend many times.
I checked the battery and it is fully charged. The ground wire is secure and clean.
While the coach exit door was closed I started the ignition to see if the automatic retraction would work....it would not.
I'm no mechanic but the angle and position of the linkage (arm) looks strange to me. It looks like it's riding high on the "pin" or shaft end. Please looks at the photos below and see if this is a normal position for it when the steps are extended.
I think since it worked before, it may be electrical. Do you have either:
a "step safety switch" inside the door to disable the automatic deploy / retraction of the steps? Our rig does - but it has a red safety light to let you know it's on.
a battery disconnect switch that may have been hit? I think our steps work off the chassis battery - not the coach battery - and one time we accidently hit this switch and it was the ONLY reason why couldn't get the steps in...
(I felt like a goof)
