When your Lippert electric coach step stops responding, the control module is often the culprit. This direct-replacement module restores full operation to single, double, or triple electric Lippert coach steps and Stromberg Carlson sliding steps -- no rewiring required.
The Lippert 301702 control module is the brain behind your electric coach step system. It houses all the circuits and electrical components necessary to sequence step deployment and retraction, manage door-trigger signals, and protect the motor from fault conditions. If your steps no longer extend or retract on command -- or operate erratically -- this module is the first component to diagnose.
This module is a factory-matched replacement for Lippert electric coach steps and Stromberg Carlson sliding steps. It mounts under the base of the step assembly using four self-tapping screws, tucking neatly out of view and connecting directly to the existing wiring harness via weatherproof connectors.
Works with single, double, and triple electric Lippert coach steps and Stromberg Carlson sliding steps -- one module covers multiple step configurations.
Wiring and connectors are weatherproofed to resist moisture, road debris, and the harsh undercarriage environment typical of coach step mounting locations.
All necessary circuits and electrical components are pre-installed. No component-level soldering or bench repair needed -- swap the module and go.
Installs under the step base with four self-tapping screws. Mounting hole pattern is fixed so alignment is straightforward on compatible step assemblies.
The control module receives a signal from the coach door switch (or manual override) and drives the step motor to extend or retract the steps. It also monitors for fault conditions that could stall or damage the motor. A failed module typically presents as steps that are completely unresponsive, steps that extend but will not retract (or vice versa), or steps that move erratically. Replacing the module is a common first repair before condemning the motor or harness.
The module mounts on the underside of the step base frame. Use the fixed mounting hole pattern (5-1/4 in. center-to-center on the long axis, 3-1/8 in. center-to-center on the short axis) to position the module. Four self-tapping screws secure it in place. Plug the existing wiring harness connectors into the module -- the weatherproof connectors are keyed to prevent incorrect insertion.
