How to Fix / Troubleshooting
Safety first: Turn off power at the breaker.
Steps:
- Inspect blower: Remove the front cover and check the cross-flow blower wheel for heavy dust buildup or foreign objects.
- Clean blower: Use a soft brush and vacuum to clean the blades. Avoid bending them.
- Spin test: With power OFF, spin the blower by hand to ensure it moves freely.
Repair: If F6 persists, the indoor fan motor or its feedback circuit is likely faulty. Replacement of the motor assembly is usually required and may be done by an experienced DIYer; PCB replacement should be done by a technician.
