Preparing for Blower Wheel Removal
Before you begin, it’s essential to gather the necessary tools and materials. You’ll need a wrench or socket set, a set of screwdrivers, a mild detergent, and a clean, well-lit work area.

- Identify the Covers: Locate the front and side panels of the Gree mini split unit. These panels will need to be removed to access the blower wheel and other internal components.
- Disconnect the Panels: Carefully remove any screws or fasteners that are holding the front and side panels in place. Be mindful of any electrical connections or wiring that may be attached to the panels.
- Expose the Blower Wheel: With the panels removed, you should now have a clear view of the blower wheel and the surrounding components.
Locating the Set Screw
- Identify the Set Screw: On the right-hand end of the blower wheel, you should see a set screw that needs to be removed. This set screw secures the blower wheel to the motor shaft.
- Use the Appropriate Tool: Depending on the size of the set screw, you’ll need to use a wrench or socket set to loosen and remove it. Ensure that you have the correct tool size to avoid stripping the screw.
- Remove the Set Screw: Carefully turn the set screw counterclockwise to loosen it, and then remove it completely.
Removing the Blower Wheel
- Gently Lift the Blower Wheel: With the set screw removed, you should now be able to gently lift the blower wheel straight up and out of its housing. Be extremely careful during this step to avoid damaging the wheel or any surrounding components.
- Inspect the Blower Wheel: Once the blower wheel is removed, take a close look at it for any signs of damage or excessive wear. This will help you determine if the wheel needs to be replaced or if it can be cleaned and reinstalled.
Cleaning the Blower Wheel
- Use a Mild Detergent: If the blower wheel is dirty, use a mild detergent and warm water to clean it. Avoid using any cleaning solutions with an alkaline base, as they can damage the residue on the blower wheel.
- Rinse Thoroughly: After cleaning, make sure to rinse the blower wheel thoroughly with clean water to remove any remaining detergent.
- Dry the Blower Wheel: Allow the blower wheel to air dry completely before proceeding with the reassembly process.
Reassembling the Unit
- Reverse the Disassembly Process: To reassemble the Gree mini split unit, simply reverse the steps you followed during the disassembly process. Carefully replace the blower wheel, secure the set screw, and then reattach the front and side panels.
- Ensure Proper Fastening: Make sure that all screws and covers are securely fastened before turning the unit back on. Double-check for any loose connections or components.
- Test the Unit: Once the reassembly is complete, turn the Gree mini split unit back on and verify that the blower wheel is functioning correctly.
Remember, if you’re not comfortable performing this task yourself or if you encounter any issues during the process, it’s always best to consult a professional HVAC technician for assistance.
