AC Fan Motor
Part #4681A20122B
This outdoor DC motor assembly is a genuine replacement component designed for use in air conditioning and heat pump systems. It powers the outdoor fan, which circulates air across the condenser coils to support efficient cooling and heating. By converting electrical energy into rotational motion, the motor helps regulate airflow and maintain consistent temperature control. A failing motor may cause symptoms such as reduced airflow, unusual noise, vibration, or a humming sound without rotation. Replacing the motor can restore proper operation, improve energy efficiency, and reduce noise. Installation should be performed with the power disconnected to ensure safety. This part is compatible with select models and should be verified for fit before installation.

Part #5901A20017H
This is a cross flow fan assembly for an air conditioner. This is a genuine replacement part sourced directly from the original manufacturer. A cross flow fan assembly is a key part of your air conditioner. It prevents the internal parts of your appliance from overheating by creating a wide and even flow of air throughout the inside of the air conditioner. If you are noticing your appliance getting too warm or overheating, it is recommended to stop using the appliance before replacing the fan. Continuing to use the appliance could cause internal damage to other parts. It is made entirely of plastic, and is off-white in color. This part is sold individually.

Plastic fan broke when I attempted to clean it

The inside air blower for the LG mini-split collects lint and clogs up. Removing the broken blade requires removing the outer plastic housings, then screws at each end of the blower housing. Some screws at the control end require removing the control units first. There is a set screw that connects the fan to the motor shaft at the control end. There is a missing blade in the fan to allow access. This screw was lock-tighted in place and required significant force to loosen. The new fan took some wiggling to get it onto the shaft. Then replace the screws at each end of the fan housing, followed by the control unit screws, and the plastic outer covers. It was not an easy job. I used more care with a small bottle brush to clean the second fan unit and avoided breaking that fan.
