Why AUX Air Conditioner shows P7 error?
If your AUX Air Conditioner displays error code P7, it indicates anti-freezing protection in the refrigeration room. This is a protection shutdown that occurs due to the temperature of the indoor coil. Check whether the indoor air inlet is blocked or not.
Why AUX Air Conditioner shows P6 error?
If your AUX Air Conditioner displays error code P6, it indicates indoor high temperature protection. This is a protection shutdown that occurs due to the temperature of the indoor coil. Check whether the indoor air inlet is blocked or not.
How to fix E1 error on AUX ASW-H12C5B4/FAR3DI-B8 Air Conditioner?
If your AUX Air Conditioner displays error code E1, it indicates an indoor unit temperature sensor error. This is detected as a short circuit or open circuit during the main PCB's inspection of the indoor unit. 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? for frequency conversion machine).
What to do if AUX Air Conditioner shows P2 error?
If your AUX Air Conditioner displays error code P2, it indicates high-pressure protection. This happens when the high-pressure switch is disconnected three times, either in standby or during operation. Check whether the plug-in terminals are firmly connected and whether the terminals and the main PCB are welded loosely.
What does P8 error mean on AUX 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.
What does F1 error mean on AUX Air Conditioner?
An F1 error on your AUX Air Conditioner indicates a module protection error, which safeguards the unit from overcurrent, overvoltage, or overheating. Check if the order of compressor wires is incorrect, causing the compressor to rotate in reverse.
What does F7 error mean on AUX Air Conditioner?
If your AUX Air Conditioner displays error code F7, it indicates an OVP (overvoltage protection) or UVP (undervoltage protection) error. This occurs when the supply voltage is lower than 135V or higher than 275V. Begin by checking the supply environment of the user.
What to do if AUX Air Conditioner shows E5 error?
If your AUX Air Conditioner displays error code E5 (or 5E), it indicates a communication error between the indoor and outdoor units. The frequency converter requires communication between these units to function. Check if the outdoor unit can power on and work correctly.
Why does my AUX Air Conditioner show F2 error?
An F2 error on your AUX Air Conditioner indicates a PFC protection error. This happens when the PFC board can't perform power calibration normally due to overcurrent or overvoltage. Check if the supply voltage is unstable, highly volatile, or too low (below AC 135V).
What to do if AUX ASW-H12C5B4/FAR3DI-B8 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.
