LiftMaster 041A7442 Belt Drive Motor with Travel Module
The LiftMaster 041A7442 is a belt-drive-specific motor with travel module assembly. It is built for select 1/2 HP AC belt drive openers where the motor and travel module are serviced together to restore drive movement and proper travel tracking.
The travel module is part of the opener's position feedback system, so correct matching is important. If the opener cannot learn limits, runs only partway, or gives travel-related symptoms, the cause may be the motor/travel module, the control board, wiring, or mechanical drag in the door and belt rail.

Technician Note
A travel-module motor can solve certain motor or travel feedback failures, but it will not fix a stretched belt, damaged rail, bad logic board, binding door, or incorrect travel setup.
Before Ordering Checklist
- Confirm the opener is a 1/2 HP AC belt drive model.
- Match the parts diagram to 041A7442 or 41A7442.
- Check for model references such as B550, B552, or WD832KEV only when the diagram agrees.
- Inspect belt condition, rail movement, and door balance.
- After installation, check travel limits and safety reversal.
Professional Advisory
Motor replacement involves internal opener wiring, moving drive parts, and door balance checks. Disconnect power before service, do not bypass safety devices, and use a qualified garage door technician if the diagnosis involves overheated wiring, damaged harnesses, unsafe door movement, or a door that will not stay balanced by hand.
