Our 2008 Contessa with a Lippert step has a hard time retracting, it tries to retract and then bounces open a bit and then tries to retract again, after a couple of bounces it fully retracts.
The switch( I think a reed switch) senses the retracted step but it does not stop the motor.
I do not have a good wiring diagram and so wonder if a relay is slow to open/close but do not know.
