Lippert Ground Control TT Leveling Controller | 421483 | Trailer

Restore automatic leveling control to your travel trailer with the Lippert Ground Control Travel Trailer Leveling Controller (Part #421483). Genuine Lippert OEM controller for Ground Control TT leveling systems on travel trailers — the "brain" that coordinates jack operation and level sensor input for effortless, stable setup at every campsite.

What This Controller Does

The Ground Control TT leveling controller is the central control module that manages your travel trailer's automatic leveling:

• Interprets level sensor input to determine required adjustments
• Coordinates jack operation for stable, level setup
• Enables precise manual control for custom adjustments
• Fault detection and reporting

⚠️ Must Replace with Exact Same Model

This controller must be replaced with the identical Part #421483 model. Lippert Ground Control systems use multiple controller variants that are NOT interchangeable — verify your existing failed controller matches this part number before ordering.

⚠️ NOT Compatible with Ground Control 2.0 or Ground Control 3.0

The Lippert leveling ecosystem includes three distinct Ground Control platforms that are NOT interchangeable:

• Ground Control 2.0 — 4-Point Control Module (Lippert 242623)
• Ground Control 3.0 Advantage — 4-Point Fifth Wheel Controller (2021018954 / MPN 27451)
• Ground Control TT — this listing's platform (travel trailer specific)

Verify your existing installation is a Ground Control TT (travel trailer) system before ordering.

Companion Component — Ground Control TT Touchpad

If your Ground Control TT system's touchpad has failed rather than the controller, see the Lippert Ground Control TT Leveling Touchpad (421484). Touchpad failures typically show as unresponsive controls or missing display; controller failures typically affect leveling function itself.

Touch Panel Failure Instead?

If the touch panel (not the controller) is the failure, see the Lippert Quick Level Touch Panel (425306) — cross-platform panel that works with Ground Control TT, Ground Control 3.0, and Level-Up Hydraulic.

Sensor Failure Instead?

If a remote sensor (not the controller) is the failure on your Ground Control TT system, see the Lippert Ground Control TT Remote Sensor (423094) — universal front/rear position remote sensor. Sensor failures typically show as inconsistent leveling or sensor fault codes; controller failures affect the whole system.

TT Lite Instead?

If your installation is a Ground Control TT Lite (not standard TT), see the Lippert Ground Control TT Lite Controller with Power + Bluetooth (2024017806 / MPN 32623). Different platform variant with integrated Bluetooth for smartphone app support.

Effortless Leveling for Any Camp Setup

Whether parked overnight or setting up for a week, the Ground Control TT system ensures your travel trailer is level — reducing appliance strain (refrigerators require level operation), improving comfort, and simplifying setup.
