  1. Remove the Front Cover: Slide out the horizontal vanes to detach the front cover entirely. If the face of the unit needs to be removed, locate the plastic clips on the bottom and remove them to expose the Phillips-head screws. Once the screws are removed, you can take off the face.

  2. Release the Drain Pan: Gently release the drain pan and allow it to angle downward, providing better access to the blower wheel.

  3. Remove the Blower Wheel: Locate the set screw on the right-hand end of the blower wheel and remove it. Next, remove the screws along the side to move the coil out of the way, and then carefully pull the blower wheel out.

Note: Be cautious not to force the blower wheel off the blower motor drive shaft if it is fixed, as this could potentially damage the components.

Cleaning the Blower Wheel

  1. Inspect the Blower Wheel: Closely examine the blower wheel for any visible dirt, debris, or buildup. This will help you determine the appropriate cleaning method.

  2. Rinse the Blower Wheel: Using a hose or a bucket of water, gently rinse the blower wheel to remove any loose dirt or debris. Avoid using high-pressure water, as this could damage the delicate components.

  3. Apply Cleaning Solution: If the blower wheel has stubborn buildup, you can use a mild, safe cleaner like Refrigeration Technologies Viper EVAP+. Apply the cleaner to the blower wheel and let it sit for a few minutes to allow the solution to work.

  4. Scrub the Blower Wheel: Gently scrub the blower wheel with a soft-bristled brush or a clean cloth to remove any remaining dirt or debris. Be careful not to damage the blower wheel’s fins or balance.

  5. Rinse and Dry: Thoroughly rinse the blower wheel with clean water to remove any residual cleaning solution. Ensure the blower wheel is completely dry before reassembling the unit.

Reassembling the Gree Mini Split

  1. Reinstall the Blower Wheel: Carefully insert the blower wheel back into the unit, ensuring it is properly aligned and secured. Replace the set screw and the screws along the side to secure the coil.

  2. Reattach the Drain Pan: Gently lift the drain pan back into its original position.

  3. Reinstall the Front Cover: Slide the horizontal vanes back into place to reattach the front cover. If the face of the unit was removed, replace the plastic clips on the bottom and secure the Phillips-head screws.

  4. Reinstall the Air Filters: Carefully place the air filters back into their respective positions.

  5. Power On the Unit: Restore power to the Gree mini split at the circuit breaker and turn on the unit to ensure it is functioning properly.
