- Cause: Communication failure between the indoor and outdoor units.
- Solution: Check wiring connections and ensure proper communication between the units.
- E4: Indoor Fan Motor Malfunction
- Cause: Issue with the indoor fan motor.
- Solution: Check the fan motor for any damage or blockages and replace if necessary.
- E6: Outdoor Fan Motor Malfunction
- Cause: Issue with the outdoor fan motor.
- Solution: Check the fan motor for any damage or blockages and replace if necessary.
- H6: Compressor Position Detection Circuit Error
- Cause: Issue with the compressor position detection circuit.
- Solution: Check the circuit for any damage or malfunctions and replace if necessary.
- F0: Refrigerant Leakage Detection
- Cause: Refrigerant leak in the system.
- Solution: Check for refrigerant leaks, ensure proper refrigerant charge, and inspect the system for any blockages or restrictions.
- H1: Air Conditioner Not Heating
- Cause: Air conditioner stopped heating due to low refrigerant charge.
- Solution: Check refrigerant levels and recharge if necessary.
- H3: Compressor Overload Protection
- Cause: Compressor overload protection triggered due to low refrigerant charge.
- Solution: Check refrigerant levels and recharge if necessary.
- H5: IPM Module Protection
- Cause: IPM module temperature too high.
- Solution: Check the IPM module for any damage or overheating and replace if necessary.
- H7: Compressor Synchronism
- Cause: High pressure, low voltage, or bad connections.
- Solution: Check for any blockages or restrictions in the system, ensure proper voltage supply, and inspect wiring connections.
- U7: 4-Way Valve Malfunction
- Cause: Bad connection, solenoid failure, or valve malfunction.
- Solution: Check the valve for any damage or malfunctions and replace if necessary.
- F1: Indoor Air Temp. Thermistor
- Cause: Bad connection or failure of indoor air temperature sensor.
- Solution: Check the sensor for any damage or malfunctions and replace if necessary.
- F2: Indoor Coil Temp. Thermistor
- Cause: Bad connection or failure of indoor coil temperature sensor.
- Solution: Check the sensor for any damage or malfunctions and replace if necessary.
- F3: Outdoor Air Temp. Thermistor
- Cause: Bad connection or failure of outdoor air temperature sensor.
- Solution: Check the sensor for any damage or malfunctions and replace if necessary.
- F4: Outdoor Coil Temp. Thermistor
- Cause: Bad connection or failure of outdoor coil temperature sensor.
- Solution: Check the sensor for any damage or malfunctions and replace if necessary.
- F5: Compressor Discharge Temp. Thermistor
- Cause: Bad connection or failure of compressor discharge temperature sensor.
- Solution: Check the sensor for any damage or malfunctions and replace if necessary.
- F6: Capacitor Overheating
- Cause: Capacitor overheating due to low fan speed.
- Solution: Increase fan speed to reduce capacitor temperature.
- F7: System Oil Leakage
- Cause: System oil leakage.
- Solution: Check for any oil leaks and repair or replace the affected components.
- F8 and F9: Compressor Failure at Low Speed
- Cause: Compressor failure due to low speed.
- Solution: Check for any blockages or restrictions in the system and ensure proper compressor operation.
- FF: Absence of Power on One or More Phases
- Cause: Power loss on one or more phases.
- Solution: Check the electrical supply and ensure proper power distribution.
