Cleaning the blower fan of your Fujitsu mini split is essential for maintaining optimal performance and energy efficiency. In our experience, regular cleaning prevents dust buildup that can impede airflow. Here’s a step-by-step guide to help you through the process:
- Turn Off the Power: Ensure the unit is completely powered down by unplugging it or switching off the circuit breaker.
- Remove the Front and Top Covers: Carefully unscrew and detach the front panel and top side covers to access the internal components.
- Detach the Electrical Section: Locate and remove the control box and any connected thermistors or wiring that may obstruct access to the blower fan.
- Separate the Coil from the Blower Fan: Unscrew the necessary components to gently separate the evaporator coil from the blower fan assembly.
- Unclip the Bottom Cover: Release the bottom cover from its tabs to fully expose the blower wheel.
- Remove the Blower Wheel: Carefully disconnect the blower wheel from the motor and drain pan.
- Clean the Blower Wheel: Use a non-acidic cleaner to thoroughly clean the blower wheel, removing all dust and debris. Rinse with warm water and allow it to dry completely.
- Lubricate the Fan Holder: Apply silicone grease to the fan holder to ensure smooth operation upon reassembly.
- Reassemble the Unit: Carefully reattach all components in the reverse order of disassembly.
Regular maintenance, including cleaning the blower fan, helps in extending the lifespan of your Fujitsu mini split system and ensures efficient operation. If you’re not comfortable performing these steps, it’s advisable to seek assistance from a professional HVAC technician.

Regular cleaning of the blower fan is crucial as accumulated dust and debris can lead to reduced airflow, decreased efficiency, and potential system malfunctions. In our professional experience, we recommend scheduling this cleaning at least once a year, or more frequently if the unit operates in a dusty environment.
It’s important to use non-acidic cleaners specifically designed for HVAC systems to avoid corrosion or damage to the blower wheel. Additionally, ensuring that all components are completely dry before reassembly prevents mold growth and maintains indoor air quality.
