When an electric entry step stops extending or retracting cleanly, the control module is one of the first things worth checking before assuming the motor itself is bad. This Lippert step controller is a genuine replacement part built for camless electric step systems.
It connects through a factory plug, so installation is a matter of swapping the old controller for this one rather than cutting and splicing wires.
Confirm your step system uses a camless electric mechanism before ordering - this controller is not a fit for scissor or cam-style step motors.
