This is the factory replacement control module for Lippert Revolution electric entry steps and TT Revolution slide-out steps. It manages motor direction, obstacle detection, and door-trigger signals so your steps deploy and retract reliably every time. If your Revolution steps have stopped responding, run erratically, or fail to retract, this module is the most common root-cause repair -- and it swaps in without modifying your existing wiring harness.
The Lippert 47-0034 control module is engineered specifically for the Revolution step series and TT Revolution slide application. It reads the door-switch signal, drives the step motor in the correct direction, monitors current draw to detect obstacles, and cuts power instantly if the step meets resistance -- protecting both the mechanism and anyone standing nearby.
The module housing is heavy-gauge steel with a black powder coat finish, built to live in the exposed undercarriage environment. Wiring connectors are sealed against moisture and road grime, so you don't have to wrap them in self-amalgamating tape or relocate them to a dry bay.
Factory-sealed wiring connectors resist moisture, road spray, and corrosion -- no additional weatherproofing needed at installation.
Built-in current-sensing logic halts step travel immediately if an obstruction is detected, preventing damage to the step mechanism or injury.
Engineered to control steps rated at up to 750 lbs, consistent with Lippert Revolution series structural ratings.
Mates directly to the existing Revolution step wiring harness -- no splicing or adapter cables required for a straightforward swap.
The control module is the electronic brain of the Lippert Revolution step system. It receives a 12V door-open or door-close signal from the coach door switch or a manual override switch, then sends the appropriate drive signal to the step motor. Key functions include:
Before replacing the module, confirm 12V power is present at the harness and that the door switch is functioning. If power and switch check out, the control module is the next logical replacement.
