Removing the blower wheel from a Daikin mini split can be a delicate task, but with the right approach and attention to detail, it can be accomplished successfully. This comprehensive guide will walk you through the step-by-step process, providing advanced tips and technical insights to ensure a smooth and efficient blower wheel removal.
Preparing for Blower Wheel Removal
Before you begin, ensure that you have the necessary tools and equipment on hand, including a screwdriver set, a digital angle gauge, a permanent marker, and a magnetic screwdriver. Additionally, make sure the unit is powered off and unplugged from the power source to prevent any electrical hazards.
Step 1: Remove the Front Cover

Start by unscrewing the screws located at the bottom of the Daikin mini split unit. This will allow you to remove the front cover, providing access to the internal components.
Step 2: Lower the Drain Pan
The drain pan in the Daikin mini split is not physically attached to the unit. Carefully lower the drain pan to gain better access to the blower wheel and its surrounding parts.
Step 3: Loosen the Set Screw
Locate the set screw that secures the blower wheel to the blower motor shaft. Using a screwdriver, gently loosen the set screw, taking care not to remove it completely.
Step 4: Remove the Screws on the Evaporator Coil
Identify the three screws on the left side of the evaporator coil. Remove these screws, which will allow you to lift the coil out towards you. This step is crucial, as it will expose the blower wheel and enable you to remove it.
Step 5: Removing the Blower Wheel
With the evaporator coil lifted, you can now grab the blower wheel and carefully pull it out. Be mindful of the bearing located on the left side of the blower wheel, as it is essential to avoid losing or damaging this component.
Advanced Tips for Blower Wheel Removal
To ensure a successful and precise reassembly, consider the following advanced tips:
Use a Digital Angle Gauge
Before removing the blower wheel, use a digital angle gauge to measure the angle of the blower motor shaft. This information will be crucial when reassembling the unit, as you’ll need to ensure the blower wheel is properly aligned.
Mark the Set Screw Position
Prior to loosening the set screw, use a permanent marker to mark its position on the blower motor shaft. This will help you align the set screw correctly during the reassembly process.
Utilize a Magnetic Screwdriver
To prevent losing any screws during the disassembly and reassembly process, use a magnetic screwdriver. This will keep the screws securely attached to the driver, reducing the risk of misplacing them.
Cleaning and Reassembly
When cleaning the blower wheel, avoid using harsh chemicals and instead opt for a gentle water-based cleaning solution. Be cautious not to damage the bearing during the cleaning process.
To reassemble the Daikin mini split, simply reverse the steps you took to remove the blower wheel. Ensure that the blower wheel is properly aligned and that the set screw is tightened securely. Double-check the angle of the blower motor shaft to ensure it matches the initial measurement.
Conclusion
Removing the blower wheel from a Daikin mini split requires attention to detail and a methodical approach. By following the steps outlined in this comprehensive guide and incorporating the advanced tips, you can successfully remove, clean, and reassemble the blower wheel, ensuring the continued efficient operation of your Daikin mini split system.
