The switches rarely fail, inside the switch
But wires break, and connections to the step wiring harness corrode if not properly protected
The early switches and control board design used normally open switches, and the door magnet closed the switch
A, closed connected circuit signaled the door was closed, and step should come up and stay up
But if a wire was broke, or if the door rattled enough to move the magnet away from the switch, the step would come down
Eventually they reversed the design of the board and the switch
To a normally closed switch that is open when the door is closed
And if a wire breaks, the step does not come out
It reduces damage to the step and the RV, from a step dropping down, catching a curb or drive way etc..
As to the OP, his motor either has a bad spot on the commutator or worn out sticky brushes, and it will keep getting worse
The proper thing to do is replace it while it will go out,
While he has access to the motor
