Removing the fan blade on an LG mini split can be a delicate task, but with the right tools and knowledge, it can be done safely and effectively. This comprehensive guide will walk you through the step-by-step process of removing the fan blade, including detailed instructions and expert-level technical details to ensure a successful DIY project.
Prepare the Indoor Unit
-
Locate and Remove the Filter: The first step is to locate the filter, which is typically situated at the bottom of the indoor unit. Gently slide out the filter or press the release latch to remove it.
-
Identify and Remove the Screws: Examine the front cover of the indoor unit and locate the screws that hold it in place. These screws are usually positioned along the edges of the cover. Use the appropriate screwdriver or socket to remove each screw carefully.
-
Disconnect the Electrical Connectors: Before you can access the fan blade, you’ll need to disconnect the electrical connectors attached to the fan motor. These connectors are typically two in number, one for the fan motor and one for the compressor. Carefully unplug each connector, taking note of their positions for proper reconnection later.

Locate the Set Screw: Once the electrical connectors are disconnected, you can focus on the fan blade itself. Locate the set screw that secures the fan blade to the motor shaft. This set screw is usually a small, hexagonal-headed bolt.
-
Remove the Set Screw: Using the appropriate wrench or socket, slowly and carefully loosen the set screw by turning it counterclockwise. Apply steady pressure to avoid stripping the screw head.
-
Carefully Lift the Fan Blade: With the set screw removed, you can now gently lift the fan blade off the motor shaft. Be cautious during this step to avoid damaging the motor or any other components.
Inspect the Fan Blade
-
Examine the Blade for Damage: Before reinstalling the fan blade, take the time to thoroughly inspect it for any signs of wear, cracks, or other damage. If the blade is damaged, it’s recommended to replace it with a new one to ensure proper airflow and system performance.
-
Check the Motor Shaft: While the fan blade is removed, also inspect the motor shaft for any signs of wear or damage. Ensure that the shaft is clean and free of any debris or obstructions.
Reinstall the Fan Blade
-
Align the Fan Blade: Carefully slide the fan blade back onto the motor shaft, ensuring that it is properly aligned and seated.
-
Secure the Set Screw: Using the same wrench or socket, tighten the set screw by turning it clockwise. Apply the appropriate amount of torque to ensure the fan blade is securely fastened and won’t come loose during operation.
-
Reconnect the Electrical Connectors: Reconnect the electrical connectors to the fan motor and compressor, making sure to match the original positions.
-
Replace the Front Cover: Finally, replace the front cover of the indoor unit and secure it with the screws you removed earlier. Ensure that all screws are tightened properly to maintain the unit’s integrity.
