Did u check the magnets on the screen door and/or front door. Sometimes they are located on the door frame. If they broke or fell off that could be the problem.
That's typical for the case where the steps won't retract when the door is closed. But if the steps won't extend when the door is opened it's most likely some other issue since the open door will break the "closed door" circuit informing the controller to extend the steps.
A friend had this "steps won't extend" issue on his Class A. We discovered that if I banged on the motor a bit with a rock, they'd work. Most likely cause was a flat spot on the motor armature which he then replaced fixing the problem. The motor used by Kwikee is a Ford electric window motor as I recall.
