Lippert 3-Point Hydraulic Leveling Controller | 2021123312 | Class C

Restore automatic 3-point leveling control to your Class C motorhome with the Lippert 3-Point Hydraulic Leveling System Controller (Part #2021123312 / MPN 28247). Genuine Lippert OEM controller (brain box) — the electronic control unit for Lippert's 3-point hydraulic leveling systems on Class C RVs. Water-resistant design for reliable performance in diverse weather conditions. Supersedes SKU 691805. Made in USA. Backed by 1-year warranty.

⚠️ Controller Only — Not Complete System

Important buyer note: despite the "3-Point Hydraulic Leveling System" naming, this listing is the electronic controller (brain box) only. Other leveling system components (jacks, pump, harnesses, sensors) are sold separately. Right choice for buyers whose controller has failed but the rest of the leveling system is intact.

⚠️ For Class C Motorhomes

This controller is engineered specifically for the 3-point hydraulic leveling configuration used on Class C motorhomes. Verify your leveling system is a Lippert 3-point Class C configuration before ordering.

⭐ Water-Resistant Construction

Standout durability feature: water-resistant design — meaningful for the exposed underside installation typical of RV leveling controllers. Handles diverse weather conditions and road spray without compromising reliability.

⭐ Supersedes Prior SKU 691805

Meaningful supersession — the 2021123312 (MPN 28247) is the current-production successor to SKU 691805. If your existing controller carries the 691805 part number, this is the direct replacement.

What This Does

The controller (brain box) is the electronic control unit that manages the 3-point hydraulic leveling process on your Class C motorhome. Meaningful for:

• Reading level sensor input to determine coach orientation
• Commanding hydraulic jack extension/retraction to achieve level
• Managing the automatic leveling sequence
• Interfacing with the user control panel

Common failure symptoms suggesting controller replacement:

• Leveling system doesn't respond to control panel input
• Erratic or incomplete leveling sequences
• Water damage to the controller housing
• Diagnostic fault codes pointing to controller failure

Different Lippert Leveling Platform?

Lippert makes multiple distinct leveling platforms — controllers are NOT interchangeable between them:

• 3-Point Hydraulic Class C (this listing)
• Level Up hydraulic — 4-point/6-point hydraulic leveling for Class A / fifth wheels
• Power Gear — automatic double-acting leveling
• Ground Control 2.0 / 3.0 / TT / TT Lite — separate controller and hardware platforms

Verify your system is a 3-point Class C hydraulic system specifically before ordering.
