|-
| 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
| 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.
|-
| E7
| Outdoor Feedback Fault
|
* Check whether the winding resistance and operation current of the compressor are normal.
* Check whether the high and low pressure is normal when the unit is running.
* Check whether the indoor and outdoor wiring is right; when it is wrong, refer to the wiring diagram.
* Check whether the contact of the inserter on the circuit board and the connection is well. Repair if otherwise.
* Check whether the signal feedback wire is disconnected. Replace or reconnect the feedback signal wire.
* Check whether the supply power is phase-lacking or phase opposition.
* Check whether the AC electromagnetic contractor is well.
|-
| E8
| Frost/Overheat Protection
|
* Check whether the filter of the indoor unit is dirty or blocked. Clean if it is dirty.
* Check whether the indoor fan is running normally, and replace the motor if it is abnormal.
* Check whether indoor pipe temperature sensor is normal, and replace the sensor if it is abnormal.
* Check whether the system pressure is normal, if abnormal, you should check whether there is leakage and fill the refrigerant if need be.
