How to Fix / Troubleshooting
Safety first: Turn off power before removing the indoor unit cover.
- Check for obstructions: Remove the front panel and ensure nothing is blocking the blower wheel.
- Inspect motor connector: Locate the indoor fan motor plug on the PCB and ensure it is fully inserted.
- Test fan operation: Restore power and run the unit. If the fan fails to start or runs erratically, the motor is likely faulty.
- Replace motor: Remove the blower assembly and replace the indoor fan motor with a Haier-compatible part. If a new motor does not resolve F8, the indoor PCB may need replacement.
