LiftMaster 041ASWG-0438SA 24V DC Motor for LA400 Swing Gate Operators
The LiftMaster 041ASWG-0438SA is a 24V DC replacement motor used to restore drive power in select LiftMaster swing gate operator arms. In a swing gate system, the motor supplies the mechanical force that extends or retracts the actuator assembly so the gate can open and close. When the motor is weak, damaged, or electrically failed, the operator may run intermittently, stall under load, move slowly, or fail to move the gate even when the control board is calling for motion.
This part is most commonly associated with LiftMaster LA400 and LA400UL swing gate operators, and it may also appear in related swing gate service documentation where the operator parts diagram calls for 041ASWG-0438SA. Because LiftMaster swing gate operators have had multiple generations, UL versions, solar configurations, and single/dual-gate setups, the motor should be matched by part number and diagram before ordering.

Technician Note
Before replacing the motor, disconnect the operator according to the manual and check that the gate swings freely by hand. A motor can be damaged by a gate that is heavy, dragging, out of level, over-traveling, or hitting a hard stop.
Before Ordering Checklist
- Confirm the exact operator model and production version
- Match the existing motor number or operator parts diagram
- Check battery voltage and charging condition before condemning the motor
- Inspect the arm assembly, rear connector, gate brackets, and hinges
- Verify all safety devices are connected and functioning before returning the gate to service
Professional Advisory
Motor replacement involves moving gate hardware and electrical connections. Do not bypass safety inputs, force the gate to run, or adjust the operator to overcome a binding gate. Use a qualified gate technician for motor diagnosis, wiring checks, and unsafe gate movement.
Product Questions & Answers
Is the 041ASWG-0438SA motor a 24V DC replacement motor?
Yes. The 041ASWG-0438SA is listed as a 24V DC motor replacement for select LiftMaster swing gate operator applications, especially LA400 series service paths where the parts diagram calls for this motor.
Does this motor fit the LiftMaster LA400?
It is commonly listed for LA400 and LA400UL swing gate operator applications. The safest way to confirm is to match the operator model, production version, arm assembly, and existing motor part number.
Is this the same as 41ASWG-438SA?
41ASWG-438SA is a commonly listed related number for the 041ASWG-0438SA motor. Use the current 041ASWG-0438SA number when checking ordering and service documentation.
Does this motor include the full gate arm?
No. This listing is for the replacement motor service part, not the complete swing gate operator arm, control board, battery, brackets, or complete operator kit unless otherwise stated by the seller.
What else should be checked before replacing the motor?
Check the gate hinges, arm geometry, battery condition, control board output, wiring, limits, and safety devices. A weak battery, binding gate, or control-board problem can look like a bad motor.
