What it means
Indoor fan motor or fan system error.
Possible causes
Fan motor not rotating Blocked or seized blower wheel Defective fan capacitor or inverter drive circuitry
Suggested fix
Check for mechanical obstruction and free rotation of the indoor fan, then test motor windings and drive output; replace the fan motor or indoor PCB once diagnostic measurements confirm the failed component.
Safety first. Isolate the power supply before inspecting any unit. Refrigerant-circuit
