LG Air Conditioner DC Motor - 4681A20042E

Ensure your cooling system runs quietly and efficiently with the LG Air Conditioner DC Motor (Part Number: 4681A20042E). This high-performance blower motor is responsible for driving the fan that circulates cool air throughout your space. If your air conditioner is making unusual grinding noises, vibrating excessively, or failing to blow air despite being powered on, the motor may be burnt out or seized, making this replacement essential for restoring airflow.

Designed for precision and energy efficiency, this DC-powered motor offers smoother speed transitions and quieter operation compared to standard AC motors. Its robust construction ensures it can handle continuous use during peak summer months while maintaining stable RPM levels for consistent cooling.

1. Safety First: Turn off the air conditioner and disconnect it from the power supply to prevent electrical shock.
2. Access the Fan Assembly: Remove the front grille and the main outer casing of the unit. You may need to remove the evaporator coil housing to reach the motor.
3. Remove the Fan Blade: Carefully loosen the set screw on the blower wheel (fan blade) and slide it off the motor shaft.
4. Disconnect Wiring: Unplug the motor's wiring harness from the main control board, noting the wire routing.
5. Swap the Motor: Unscrew the mounting brackets holding the old 4681A20042E motor in place. Install the new motor and secure the brackets.
6. Reassemble: Reattach the fan blade to the new shaft, reconnect the wiring, and replace the unit casing before restoring power for testing.
