Error Codes

Code	Error Name	Troubleshooting
DF	Defrost	Currently in defrost mode. Will return to normal operations when defrost is finished.
FF	Outdoor Low Temperature Indication	The current temperature outside is too low for proper unit functionality.
F1	Communication Fault	The communication wire is broken off. Please check the state of the wire. Please check whether the electrical control board is damaged. It should be replaced if damaged. Please check whether the power ground wire is reliable. Please check for outside interference. If found, remove the outside interference.
F2	Indoor Temperature Sensor Fault	Check whether the resistance of the sensor is normal. If it is abnormal the sensor should be replaced. Check whether there is a short circuit or open circuit in the wire of the sensor, and whether the plug is connected correctly. After checking for the above conditions and finding nothing, check the electric control board.
F3	Indoor Coil Temp. Sensor Fault	Check whether the resistance of the sensor is normal. If it is abnormal the sensor should be replaced. Check whether there is a short circuit or open circuit in the wire of the sensor, and whether the plug is connected correctly. After checking for the above conditions and finding nothing, check the electric control board.
F4	Indoor Motor Fault	Check whether the contact of the plug of the motor wire and socket is in good condition. Make sure it is well contacted. Check whether the indoor motor is damaged. If it is damaged, replace it. Check whether the controllable silicon and other components of the electric control board are are damaged. Please replace board if that is the case. Check whether the indoor motor is being obstructed when running.
F5	IPM Protection	Check whether the supply voltage is over the acceptable range.
F6	Outdoor Sensor Fault	Check whether the resistance of the sensor is normal, otherwise replace it. Check whether there is a short circuit or open circuit in the wire of the sensor, and whether the plug is connected correctly. After checking for the above conditions and finding nothing, check the electric control board.
F7	Outdoor Coil Temperature Sensor Fault	Check whether the resistance of the sensor is normal. If it is abnormal the sensor should be replaced. Check whether there is a short circuit or open circuit in the wire of the sensor, and whether the plug is connected correctly. After checking for the above conditions and finding nothing, check the electric control board.
F9	Exhaust Gas Sensor Failure	Check whether the resistance of the sensor is normal, otherwise replace it. Check whether there is a short circuit or open circuit in the wire of the sensor, and whether the plug is connected correctly. After checking for the above conditions and finding nothing, check the electric control board.
