What does F4 error mean on AUX Air Conditioner?
If your AUX Air Conditioner displays error code F4, it indicates an exhaust sensor error. This occurs when the outdoor unit main PCB detects a short circuit or open circuit in the exhaust sensor. Check if there is any evident resistance problem in the sensor.
How to fix F6 error on AUX ASW-H18E3B4/FAR3DI-C0?
If your AUX Air Conditioner displays error code F6, it indicates an outdoor unit temperature sensor error. This is detected as a short circuit or open circuit during the outdoor unit main PCB's inspection. Check whether there’s resistance problem, short circuit or open circuit in the sensor; the resistance value shall be within a reasonable range (15K? under the temperature of 25?).
How to troubleshoot E2 error on AUX ASW-H18E3B4/FAR3DI-C0 Air Conditioner?
If your AUX Air Conditioner displays error code E2, it indicates an outdoor unit coil sensor error. This is detected as a short circuit or open circuit during the inspection of the outdoor unit's main PCB. Check whether there’s resistance problem, short circuit or open circuit in the sensor; the resistance value shall with a reasonable range (about 20K? for frequency conversion machine).
How to troubleshoot E3 error on AUX ASW-H18E3B4/FAR3DI-C0 Air Conditioner?
If your AUX Air Conditioner displays error code E3, it indicates an indoor unit coil sensor error. This is detected as a short circuit or open circuit during the inspection of the indoor unit's main PCB. Check whether there’s resistance problem, short circuit or open circuit in the sensor; the resistance value shall with a reasonable range (about 20K? for frequency conversion machine).
What to do if AUX Air Conditioner shows E0 error?
If your AUX Air Conditioner displays error code E0, it means the main PCB has detected that the system's working current is too high, triggering overcurrent protection. As a result, the air conditioner will stop running. To resolve this, inspect the current transformer, power line, compressor line, and connector assembly.
What causes F3 error on AUX ASW-H18E3B4/FAR3DI-C0 Air Conditioner?
An F3 error on your AUX Air Conditioner indicates a compressor out-of-step error. The module panel constantly tests the current of lead wires of the compressor and calculates the position of the rotator of the compressor when driving the compressor to work. Check if the order of compressor wires is incorrect, which makes the compressor rotate reversely.
Why AUX Air Conditioner shows P4 error?
If your AUX Air Conditioner displays error code P4, it indicates refrigeration overload protection. This happens when the outdoor coil sensor senses excessive temperature, preventing the compressor from overloading and reducing frequency. Check the coil sensor with a multimeter to see if the resistance value is normal (20K? standard sensor, 25?).
What does P3 error mean on AUX Air Conditioner?
If your AUX Air Conditioner displays error code P3, it indicates Liquid Deficiency Protection. This happens when the liquid volume of the system is less than 30%, which leads to non-refrigeration and liquid shortage protection. Check the stop valve and turn it counterclockwise with hexagons to see if the valve is not open and the opening is not enough.
What does F8 error mean on AUX ASW-H18E3B4/FAR3DI-C0 Air Conditioner?
If your AUX Air Conditioner displays error code F8, it indicates a communication error between the outdoor unit's main PCB and the module panel. This occurs when the normal communication between these components is disrupted during operation. First, check if the communication connection line (mostly 4 chips) between the module panel and main control panel is loose.
What does P8 error mean on AUX ASW-H18E3B4/FAR3DI-C0 Air Conditioner?
If your AUX Air Conditioner displays error code P8, it means that the controller has detected the AC bus current exceeding the set protection value, triggering overcurrent protection. As a result, the frequency is limited and reduced. To resolve this, use a multimeter to detect and check if the bus voltage is too low.
