Removing the fan blade on a Panasonic mini split air conditioning unit can be a delicate task, but with the right tools and a step-by-step approach, it can be accomplished successfully. This comprehensive guide will walk you through the process, providing detailed instructions and technical insights to ensure a smooth and efficient fan blade removal.

Preparing the Indoor Unit

  1. Disconnect the Power: Before beginning any work on the mini split, it’s crucial to disconnect the power supply to the indoor unit. This can typically be done by turning off the circuit breaker or unplugging the unit from the power source.

  2. Remove the Front Cover: Locate the screws on the bottom of the indoor unit and remove them using the appropriate screwdriver. This will allow you to detach the front cover and gain access to the internal components.

  3. Lower the Drain Pan: The drain pan, which is responsible for collecting condensation, is often located beneath the blower wheel. Gently lower the drain pan to provide better access to the surrounding components.

  1. Locate the Set Screw: On the far right side of the blower wheel, you will find a set screw that secures the wheel to the blower motor shaft. Use a screwdriver or Allen wrench to loosen this set screw.

  2. Identify the Bearing: On the left side of the blower wheel, you will find a bearing that supports the wheel’s rotation. Take note of its position and condition, as it will need to be reinstalled correctly during the reassembly process.

  3. Remove the Screws: Locate the three screws on the left side of the evaporator coil and remove them using the appropriate screwdriver. This will allow you to lift the coil out towards you, providing access to the blower wheel.

  1. Carefully Lift the Coil: Gently lift the evaporator coil out towards you, taking care not to damage any of the delicate fins or tubing.

  2. Grasp the Blower Wheel: Once the coil is out of the way, you can safely grasp the blower wheel and pull it out of the unit.

  3. Inspect the Bearing: Examine the bearing on the left side of the blower wheel, ensuring it is in good condition and can be reused during the reassembly process.

Cleaning and Maintenance

  1. Clean the Blower Wheel: Use a soft-bristled brush or a damp cloth to gently clean the blower wheel, removing any dust, debris, or buildup. Avoid using harsh chemicals or abrasives, as they can damage the wheel’s surface.

  2. Inspect the Blower Wheel: Carefully inspect the blower wheel for any signs of wear, cracks, or imbalance. If the wheel is damaged, it may need to be replaced.

  3. Lubricate the Bearing: If the bearing appears to be in good condition, apply a small amount of high-quality bearing lubricant to ensure smooth operation during reassembly.


  1. Reinstall the Blower Wheel: Carefully reinsert the blower wheel into the unit, ensuring that the bearing is properly aligned and seated.

  2. Secure the Evaporator Coil: Gently lower the evaporator coil back into its original position and secure it with the three screws you removed earlier.

  3. Tighten the Set Screw: Reattach the set screw on the right side of the blower wheel, ensuring that it is securely tightened.

  4. Reinstall the Drain Pan: Lift the drain pan back into its original position, making sure it is properly seated and secured.

  5. Reattach the Front Cover: Carefully replace the front cover of the indoor unit and secure it with the screws you removed at the beginning of the process.

  6. Restore Power: Finally, reconnect the power supply to the indoor unit and ensure that the mini split is functioning correctly.

By following these detailed instructions, you can successfully remove the fan blade on your Panasonic mini split air conditioning unit, perform any necessary maintenance or cleaning, and reassemble the unit with confidence.
