When the controller on your fifth wheel's electric landing gear stops responding, levelng your rig becomes a manual headache. Lippert Components part 276452 is the direct OEM replacement controller for LCI electric landing gear jack systems, restoring the push-button up/down operation your fifth wheel was built with. Compact, lightweight, and wired to plug into existing LCI harnesses, this is a straightforward swap that gets you back to one-button leveling without modifying your rig's electrical system.
Lippert Components is one of the most widely used landing gear manufacturers in the fifth wheel segment, supplying systems to brands including Grand Design, Keystone, Forest River, Heartland, and many others. The electric jack system on your fifth wheel -- whether it is a single-motor or dual-motor setup -- relies on this controller to send the correct signal to the motor relay, controlling extend and retract functions.
Part 276452 replaces a failed, cracked, or water-damaged controller unit. Because it is an OEM Lippert part, it matches the original wiring connector, button layout, and motor logic of the system installed at the factory. There is no need to splice, adapt, or reprogram -- connect the harness, secure the controller, and operate normally.
Plugs directly into existing LCI landing gear wiring harness. No splicing, no adapters required for compatible systems.
Dedicated up/down logic for electric landing gear motor operation, restoring full jack function after controller failure.
At just 0.07 lbs, the controller adds virtually no weight to the mounting location. Compact 8.45 x 5.2 x 1.7 inch footprint.
Compatible with LCI electric landing gear systems found on fifth wheels from Grand Design, Keystone, Heartland, Forest River, and others.
The Lippert electric landing gear controller acts as the operator interface between you and the landing gear motor relay. When you press the extend or retract button, the controller sends a low-voltage signal through the harness to the relay, which in turn powers the 12V DC landing gear motor in the correct direction. The controller itself does not carry the high-amperage motor current -- it handles signal logic only -- which is why a controller failure often presents as a jack that does nothing, even though the motor and relay are still functional.
If your landing gear stops responding entirely, makes no sound, and you have confirmed 12V power is present at the system, a failed controller is one of the first components to suspect before replacing the motor or relay.
Controllers mounted near the front cap or underbelly are exposed to road debris, moisture, and UV over time. Cracked housings, corroded contacts, and impact damage from low clearance situations are the most common causes of controller failure on LCI-equipped rigs.
Lippert Components produces several electric landing gear configurations used across the fifth wheel market. The 276452 controller is associated with LCI's electric stabilizer and tongue jack control systems. Common fifth wheel brands that use LCI landing gear and may be compatible with this controller include:
Always verify your existing controller part number or the part number on your landing gear system's control box before ordering, as LCI supplies multiple controller variants across different jack motor configurations.
Lippert offers several landing gear controller variants. Check the label on your existing controller or the sticker on your landing gear motor housing for a part number reference. If the label is missing, your RV's build sheet or the Lippert parts lookup tool (using your VIN or build date) can confirm which controller your rig shipped with.
Replacement is a straightforward disconnect-reconnect procedure in most cases:
After installation, apply a small amount of dielectric grease to the harness connector pins before plugging in. This helps seal out moisture and prevents the corrosion that commonly causes controller contact failure over time.
Always disconnect the trailer's 12V battery or ground before swapping the controller. Even though this controller handles signal logic and not motor current directly, working near the landing gear harness with live power present risks accidental motor activation.
