Possible Causes
Blocked indoor blower wheel, Failed DC indoor fan motor, Faulty indoor fan driver circuit on PCB, Obstructed air filters or coil causing overheat
How to Fix / Troubleshooting
Safety: Turn off power at the breaker before opening the indoor unit.
- Step 1 – Clean filters: Remove and wash the air filters with mild soap and water. Let them dry completely before reinstalling.
- Step 2 – Inspect blower wheel: Remove the front cover and carefully inspect the blower wheel for dust buildup or foreign objects. Clean with a soft brush and vacuum.
- Step 3 – Check fan rotation: Spin the blower wheel by hand (power OFF). It should rotate freely without scraping. If it binds, check for misalignment or debris.
- Step 4 – Test fan motor: Restore power and set the unit to FAN mode. If the fan does not start or is noisy, the DC fan motor may be failing and should be replaced with a Senville-compatible indoor fan motor.
- Step 5 – PCB driver check: If a new motor does not resolve E8, the fan driver circuit on the indoor PCB may be defective and require board replacement.
