Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the unit. Fan blades can be sharp; wear gloves.
- Step 1 – Check for obstructions: Remove the front cover and filters. Spin the indoor fan wheel by hand; it should rotate freely without scraping.
- Step 2 – Clean fan wheel: If heavily dust-laden, clean the blower wheel with a brush and vacuum to reduce load on the motor.
- Step 3 – Inspect motor wiring: Locate the indoor fan motor connector on the PCB and ensure it is fully seated. Check for damaged wires.
- Step 4 – Test operation: Restore power and run the unit. If the fan does not start or starts then stops with F1, the motor or its feedback sensor is likely faulty.
- Step 5 – Replace fan motor: Remove the mounting screws, slide out the fan motor assembly, and install a new Sencor indoor fan motor compatible with your model.
- Step 6 – PCB check: If a new motor does not resolve F1, the main PCB fan driver circuit may be defective and should be replaced by a technician.
