  1. Remove the Front Cover: Begin by removing the front cover of the indoor unit. This is typically done by gently pulling up on the tabs or latches located on the sides or top of the cover.

  2. Locate the Screws: Once the front cover is removed, you will see the fan blade assembly. Identify the screws that are holding the fan blade in place. These screws may be located on the top, sides, or even the back of the unit.

  3. Inspect the Screw Locations: Carefully examine the fan blade assembly and note the exact locations of the screws. This information will be crucial when it comes time to reassemble the unit.

  1. Loosen the Set Screw: If there is a set screw on the motor shaft, use a hex wrench or Allen key to loosen it. This will allow you to remove the fan blade more easily.

  2. Carefully Pull the Fan Blade: Gently grasp the fan blade and pull it straight off the motor shaft. Be cautious not to apply too much force, as this could damage the motor or other components.

  3. Inspect the Fan Blade: Closely examine the fan blade for any signs of damage, such as cracks, bends, or imbalances. If the fan blade is damaged, it will need to be replaced.

Reassemble the Unit

  1. Reinstall the Fan Blade: If the fan blade is in good condition, carefully slide it back onto the motor shaft, ensuring that it is properly aligned and seated.

  2. Tighten the Set Screw: If there is a set screw, use the hex wrench or Allen key to securely tighten it, locking the fan blade in place.

  3. Replace the Screws: Locate the screw holes and reinsert the screws that were previously removed, tightening them securely.

  4. Reattach the Front Cover: Carefully align the front cover and snap it back into place, ensuring that all the tabs or latches are properly engaged.

  5. Restore Power: Turn the power back on to the MRCOOL mini split unit.

Safety Considerations

When removing the fan blade, be mindful of the sharp edges and take necessary precautions to avoid injury. Wear protective gloves and eye wear, and work in a well-lit area to ensure visibility.
