E4 – INTERNAL FAN ERROR (INDOOR PG MOTOR) Cause: The PG motor is equipped with a speed feedback signal line. When the feedback signal is not received by the control Cause of Error panel, it has no way to recognize the fan moving. This will be indicated as “Internal fan error”. - Page 8 E5 – INTERNAL & EXTERNAL COMMUNICATION ERROR Cause: The frequency converter needs internal and external communication. When the communication cannot be reached, the internal and external units will indicate “internal and external communication error”. Only “main internal control panel, connecting cable and outdoor unit control panel” are related to communication;...
- Page 9 F0 – EXTERNAL DC FAN ERROR Cause: The main control panel will indicate “external DC fan error” when it detects an imbalanced current on the three lead wires of the drive motor. Cause of Error Inspection path: Is the DC fan stuck due to foreign material? →...
- Page 10 F1 – MODULE PROTECTION ERROR Cause: The power module is the part to directly drive the compressor to work. It can protect the machine in time when overcurrent, overvoltage or overheat occurs and stops the compressor from working. It will, at the same time, send a “shutdown request”...
- Page 11 F2 – PFC PROTECTION ERROR Cause: PFC board is a component of the inverter air conditioner for power factor correction and voltage boosting. When the PFC board cannot perform power calibration as normal because of overcurrent and overvoltage, it will indicate “PFC protection error” and Cause of Error its function may also be integrated with the module panel or main control panel.
- Page 12 F3 – COMPRESSOR OUT-OF-STEP ERROR Cause: The module panel will constantly test the current of lead wires of the compressor and calculate the position of the rotator of the compressor. When the compressor deviates far from the normal operating status , it will indicate “compressor out-of- step error”...
- Page 13 F4 – EXHAUST SENSOR ERROR Cause: The outdoor unit control panel will indicate “exhaust sensor error” and send it to the main internal control panel when it detects short circuit or open circuit of the exhaust sensor. Cause of Error Inspection path: Exhaust sensor →...
- Page 14 F5 – COMPRESSOR TOP HEAD SENSOR ERROR Cause: The compressor top head sensor is a compressor top head temperature protection switch most of the time. It keeps closed (short circuit) when the compressor temperature is normal and switches off (open circuit) when the temperature is too high.
- Page 15 F6 – EXTERNAL TEMPERATURE SENSOR ERROR Cause: The detection of short circuit or open circuit of external termperature sensor during the inspection of outdoor unit control panel, indicated by "external Cause of Error termperature sensor error". Inspection path: Sensor → Sensor wire → Connectors → Outdoor unit control panel Tools Required Multimeter, 15KΩ...
- Page 16 F7 – OVP OR UVP ERROR Cause: When the supply voltage is lower than 135V or higher than 275V, the inspection, circuit would detect over or under voltage protection signal and send it to the outdoor unit control panel and the outdoor unit control panel would initiate an "OVP or UVP error"...
- Page 17 F8 – OUTDOOR UNIT CONTROL PANEL AND MODULE PANEL COMMUNICATION ERROR Cause: Only the models with the module panels separated with the outdoor unit control panels may have this error. When the machine is running normally, the module panel and the outdoor unit control panel would coordinate with each other on the communication to work and when the communication is off, the outdoor unit control panel would raise the alarm of...
- Page 18 F9 – OUTDOOR EE ERROR Cause: Parameters are stored in an “EE” chip for the unit to run properly. The motor on the outdoor unit control panel can only work after reading the data stored in EE and if not read, the alarm "outdoor EE error"...
- Page 19 FA – RECIRCULATED SENSOR ERROR Cause: When the main control panel detects an open circuit or short circuit of the recirculated sensor, it would raise an alarm of "recirculated sensor error" and send it to the main Cause of Error internal control panel to indicate it.
- Page 20 FB – PROTECTION OF FREQUENCY CONVERSION Cause: In routine operation of the unit, there will be times where the unit will need to protect the compressor during defrost, overheating, or undercooling. Three indicator lights are used on the outdoor unit control panel to signify this Cause of Error protection is occurring.
