When your slide-out stops responding, refuses to extend, or throws fault codes, the control module is often the culprit. The Lippert 368828 is a direct-replacement electronic control unit (ECU) for LCI electric slide-out systems found across a wide range of travel trailers, fifth wheels, and motorhomes. Swapping this module restores full slide-out function without replacing motors, wiring harnesses, or other expensive components.
Lippert Components is the dominant supplier of slide-out systems in the North American RV industry, and their electric slide systems are found in rigs from Forest River, Keystone, Jayco, Coachmen, Heartland, Grand Design, Thor, and dozens of other builders. The 368828 control module sits at the heart of these systems, receiving input from the wall switch or touchpad and sending precisely timed power signals to the slide-out motor.
A failed control module typically presents as a slide that will not move in either direction, a slide that moves only one direction, or a slide that trips a breaker without any mechanical obstruction. Before replacing motors or hunting for wiring faults, confirming or replacing the ECU is standard diagnostic practice for LCI-equipped slides.
Designed to the same specification as the original factory-installed module. Plug into existing connectors without cutting or splicing.
Fits the widely used Lippert electric slide-out platform found across hundreds of RV makes and model years.
At 8.58 x 6.37 x 4.53 inches and 2.12 lbs, this module mounts in the same bay as the original with no bracket modifications required.
Replaces a failed ECU to bring extension, retraction, and limit-switch logic back to normal operation.
The slide-out control module is the brain of your LCI electric slide system. It manages the relay logic that drives the slide motor forward or reverse, monitors the built-in limit switches so the room stops at the correct fully-extended and fully-retracted positions, and provides overcurrent protection to prevent motor damage. Some revisions also incorporate a soft-start ramp to reduce mechanical stress on the gear drive and room seals.
When the module fails, power from the coach battery still reaches the unit, but the output signals to the motor are missing, erratic, or reversed. This is why a failed module can sometimes cause the slide to move in only one direction, or to ignore the wall switch entirely while still allowing manual override in some cases.
The Lippert 368828 control module applies to LCI electric slide systems. LCI electric slides are installed in a very large portion of RVs built from the early 2000s through current production. To confirm this module fits your rig, locate the existing control module (typically mounted inside an access panel near the slide motor, often under the chassis or in a front storage compartment) and match the part number printed on the original unit's label.
Replacing the Lippert 368828 control module is a straightforward swap for an intermediate DIYer comfortable working with 12V RV electrical systems. The module uses a wiring harness with keyed connectors, so incorrect reconnection is difficult. The general process involves disconnecting coach power, labeling and unplugging the existing harness connectors, removing the two to four mounting screws that secure the module to its bracket, and reversing the process with the new unit.
