Gree L3 Error Code – Outdoor DC Fan Motor Malfunction

Inspect Fan for Obstructions
Visually check the fan blades for any physical obstructions (debris, ice, damaged blades) that may be causing the lock condition. 🔧 Flashlight ⚠️ Disconnect power before inspecting fan

Manually Rotate Fan
With power off, attempt to manually spin the fan blades. Fan should rotate freely. If stiff or stuck, motor bearings may have failed. 🔧 None ⚠️ Ensure power is completely off before touching fan

Check Fan Motor Wiring
Inspect all wiring connections to the fan motor. Check for loose connectors, damaged wires, or corrosion on terminals. 🔧 Multimeter, screwdrivers

Measure Fan Motor Resistance
Disconnect fan motor connector. Measure winding resistance across motor terminals. Compare to service manual specifications. Open or shorted windings indicate motor failure. 🔧 Digital multimeter ⚠️ Disconnect power before measuring

Replace Fan Motor
If motor windings are faulty or motor is mechanically seized, replace the fan motor with the correct replacement part for the model. 🔧 Screwdrivers, spanner ⚠️ Ensure power is off and capacitors are discharged before replacing motor
