When your RV's hydraulic slide-out system stops responding or behaves erratically, the Integrated Relay Center (IRC) is often the culprit. The Lippert 140514 is the factory-correct replacement IRC and plate assembly engineered for 3-room hydraulic slide-out configurations, restoring reliable in/out operation without workarounds or splicing.
Lippert Components is the dominant OEM supplier for RV slide-out systems in North America, and the 140514 IRC assembly is built to the same specifications as the original unit installed at the factory. If your coach uses a Lippert 3-room hydraulic slide-out system and you're experiencing rooms that won't extend, won't retract, or throw fault codes, this assembly addresses the root cause at the control level.
The IRC -- Integrated Relay Center -- manages the directional valve signals and relay logic that tell each hydraulic room when and how to move. Combined with the mounting plate, this is a drop-in replacement that connects to your existing harness without custom wiring.
Engineered specifically for Lippert hydraulic slide-out systems controlling three independent slide rooms -- not a universal unit.
Includes the IRC module and mounting plate as a matched set, so you replace the entire assembly rather than individual components.
Plugs into the existing Lippert wiring harness. No splicing or adapter wiring required for a direct swap on compatible systems.
Backed by Lippert's limited 1-year manufacturer warranty for defects in materials and workmanship.
The IRC (Integrated Relay Center) is the electrical heart of Lippert's hydraulic slide-out system. It receives commands from the wall switch or control panel, then activates the correct hydraulic valves to extend or retract each room in sequence. Relay contacts inside the IRC can wear, corrode, or stick -- especially in coaches that see frequent cycling or harsh environments. When the IRC fails, symptoms include:
Replacing the IRC is a straightforward swap for anyone comfortable working with 12V DC wiring in an RV. The general process involves:
