LG Air Conditioner DC Stepping Motor - 4681AP2968N

Restore the precise airflow control and quiet operation of your indoor unit with the LG Air Conditioner DC Stepping Motor (4681AP2968N). This high-precision motor is responsible for the incremental movement of the horizontal or vertical louvers (air fins). Unlike standard motors, a stepping motor moves in fixed, discrete steps, allowing the unit to position the air deflectors at exact angles. If your air conditioner’s louvers are stuck, swinging erratically, or making a clicking sound without moving, this motor has likely failed.

The 4681AP2968N is designed for low-voltage DC operation, ensuring high energy efficiency and near-silent performance. By replacing a faulty motor, you restore the "Auto Swing" functionality and the ability to direct air precisely where it is needed, which is essential for uniform cooling and preventing cold drafts.

1. Safety First: Turn off the air conditioner and unplug it from the wall outlet or shut off the dedicated circuit breaker.
2. Access the Louvers: Open the front intake grille. The stepping motor is typically located at the side of the louver assembly, often hidden behind a small plastic cover or the main unit casing.
3. Expose the Motor: You may need to remove a few screws from the main chassis or the lower panels to reach the motor’s mounting bracket.
4. Disconnect the Wiring: Carefully unplug the small multi-pin wiring harness from the motor. These connectors are delicate; avoid pulling on the wires directly.
5. Remove and Replace: Unscrew the two mounting screws holding the old 4681AP2968N motor in place. Pull the motor away from the louver shaft. Slide the new motor onto the shaft, ensuring the keyed (D-shaped) spindle aligns perfectly with the louver slot.
6. Secure and Test: Fasten the mounting screws and reconnect the wiring harness. Reassemble the unit panels, restore power, and use the remote to test the "Swing" function to ensure smooth, full-range motion.
7. Compatible with select LG air conditioner models, this OEM-quality stepping motor ensures factory-standard precision and restores your indoor comfort.
