LiftMaster 041D1624-2 12V DC Motor with Mounting Bracket for RJO Openers
The LiftMaster 041D1624-2 is a 12V DC motor and mounting bracket kit used in select LiftMaster wall-mounted jackshaft/RJO garage door openers and light-duty commercial door operators. Unlike a rail-mounted opener motor, this motor is part of a side-mounted operator that drives the door shaft directly. That makes correct fitment especially important because the motor bracket, mounting position, shaft load, and operator control logic are specific to the RJO platform. A failed motor may show up as no movement, weak movement, excessive motor noise, or inability to move a properly balanced door. Since this part is specifically identified for 12V systems, it should not be substituted into different LiftMaster motor families.
Common Replacement Reasons
- RJO wall-mounted opener motor will not run after power and controls are verified.
- Motor struggles to move a properly balanced door.
- Motor or bracket assembly is damaged or noisy.
- Replacement needed for a 12V RJO motor listed in the opener parts diagram.

Technician Note
A wall-mounted opener should not be used to compensate for a heavy, unbalanced, or dragging sectional door. Check shaft, cable tension monitor, locks, and door balance before replacing the motor.
Before Ordering Checklist
- Confirm the opener is an RJO wall-mounted model.
- Verify the model is 8500W, 8500WLA, LJ8900W, LJ8950W, or parts-diagram compatible.
- Confirm the system is 12V and calls for 041D1624-2.
- Check door balance, shaft condition, and cable tension monitor.
- Do not confuse this with 041D1624-1 or 041-0236-000 rail-opener motor kits.
Professional Advisory
Wall-mounted opener repairs involve door shaft movement and a heavy sectional door. If the door is out of balance, has cable issues, or uses a lock system, have a qualified technician inspect it before motor replacement.
