Remove the Fan Motor

To remove the fan motor, you will need to disconnect it from the mini split unit. This process may involve removing screws or bolts that secure the motor in place.

  1. Locate the screws or bolts that hold the fan motor in place, typically 4 or more.

Locate and Remove the Fan Blade

With the fan motor removed, you can now access the fan blade itself. The fan blade is typically connected directly to the fan motor shaft.

  1. Visually inspect the fan blade and identify any screws, clips, or other fasteners that are securing it to the motor shaft.
  2. Using the appropriate tools, such as a wrench or pliers, carefully remove any screws, clips, or fasteners that are holding the fan blade in place.

Reassembly and Reinstallation

Once you have completed the fan blade removal, you can proceed with any necessary maintenance or replacement, and then reassemble the Senville mini split unit.

  1. Clean the fan blade, if necessary, using a soft cloth and a mild cleaning solution.
  2. Inspect the fan motor and ensure that it is in good working condition.
  3. Carefully reinstall the fan blade, ensuring that it is properly aligned and secured to the motor shaft.

  5. Reattach the panels or covers that were removed earlier, ensuring that they are properly aligned and secured.
  6. Reconnect the power to the Senville mini split unit and verify that the fan is operating correctly.
