Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the front cover or touching the blower.
- Step 1 – Check for obstructions: Open the front panel and inspect the cross-flow fan (blower wheel) for plastic bags, insulation, or heavy dust buildup. Clean with a soft brush and vacuum.
- Step 2 – Inspect fan motor wiring: Locate the indoor fan motor connector on the PCB and ensure it is fully inserted and not burnt.
- Step 3 – Spin test: With power OFF, gently rotate the blower wheel by hand. It should spin freely. If it is stiff or scraping, the bearings may be worn or the housing misaligned.
- Step 4 – Test operation: Restore power and run the fan-only mode. If the fan does not start or starts then stops with E8, the motor or driver is likely faulty.
When to call a technician: Replacing the indoor fan motor on a Royal Clima split unit requires partial disassembly of the indoor chassis and should be done by a professional if you are not experienced.
