Lippert 3-Point Class C Hydraulic Leveling Water-Resistant V2 Controller Lippert 2021123312 -- V2 Controller Assembly for 3-Point Class C Hydraulic Levelers

This is the genuine Lippert replacement V2 controller assembly for compatible 3-point hydraulic leveling systems installed on Class C motorhomes. If your existing controller has failed, shows erratic behavior, or is damaged from moisture exposure, this water-resistant unit restores factory-level operation and connects directly to your existing harness.

Direct OEM Replacement for Lippert 3-Point Hydraulic Leveling Systems

The Lippert 2021123312 V2 controller assembly is a genuine OEM replacement component designed specifically for 3-point hydraulic leveling systems used in Class C motorhome applications. The "V2" designation indicates the second-generation controller design, which improves on the original with enhanced water resistance and revised internal logic for more consistent auto-leveling performance.

Class C motorhomes using Lippert's 3-point hydraulic leveling layout typically deploy one front jack and two rear jacks, with the controller managing pump motor activation, jack extension sequencing, and retract/auto-level commands. This assembly is the brain of that system -- replacing it with a genuine Lippert part ensures correct signal timing and compatibility with the existing hydraulic pump and solenoid wiring.

Water-Resistant Design

Sealed housing resists moisture intrusion common in exterior or under-chassis controller mounting locations.

V2 Generation Logic

Second-generation controller with revised auto-level sequencing for more reliable jack deployment and retract cycles.

Direct Harness Plug-In

Matches the OEM connector and wiring harness of compatible Lippert 3-point Class C leveling systems -- no splicing required on supported builds.

Genuine Lippert OEM Part

Sourced directly from Lippert (part 2021123312, vendor ref 17-0949) for assured fit and function on compatible systems.

Why Replace the Controller Assembly?

  • Controller displays error codes or fails to respond to jack commands
  • Auto-level cycle starts but does not complete or terminates early
  • Buttons are unresponsive or intermittently functional
  • Moisture damage to the original controller housing
  • Upgrading from V1 to V2 generation controller on a compatible system

Compatibility -- What to Verify Before Ordering

This controller is designed for 3-point hydraulic leveling systems installed on Class C motorhomes by Lippert. Before ordering, confirm:

  • Your rig uses a Lippert 3-point hydraulic (not electric or 4-point) leveling system
  • Your current controller part number or vendor reference matches 2021123312 or 17-0949
  • The chassis is a Class C motorhome -- this controller is not intended for Class A or 5th wheel applications
  • Your system uses the V2-compatible wiring harness (check the existing connector for pin count and locking tab style)

If you are unsure of your system generation, note the part number printed on your existing controller housing or contact Lippert customer support with your coach VIN for confirmation.

Installation Notes

  • Disconnect 12V house power before removing the existing controller assembly
  • Photograph all wiring connections before removal to aid reinstallation
  • After installation, perform a full manual jack cycle and then an auto-level cycle to confirm correct operation
  • Do not operate the leveling system with the coach in motion -- jacks must be fully retracted before driving
  • This is a controller assembly only -- it does not include the hydraulic pump, jacks, solenoid valve block, or wiring harness

Maintenance Tip

After installing a new controller, check the hydraulic fluid level in the leveling pump reservoir. Low fluid can cause erratic jack behavior that mimics controller faults. Use Lippert-approved hydraulic fluid for the leveling system -- do not substitute with generic ATF unless confirmed compatible by Lippert for your specific pump model.

Important Information

  • Verify compatibility before ordering: This controller is for Lippert 3-point hydraulic leveling systems on Class C motorhomes only. It is not a universal leveling controller.
  • Controller assembly only: Does not include the hydraulic pump motor, solenoid block, jack cylinders, or wiring harness.
  • Disconnect power before installation: Always disconnect 12V house power before removing or installing any leveling system controller.
  • Never drive with jacks extended: Confirm all jacks are fully retracted after any controller replacement or service procedure before moving the vehicle.
  • Match part numbers: Cross-reference your existing controller part number (printed on the housing label) to 2021123312 or vendor reference 17-0949 to confirm a correct match.
