What causes exhaust protection in my AUX Q Series Air Conditioner?
If your AUX Air Conditioner is experiencing exhaust protection, it means the exhaust sensor is detecting that the exhaust temperature is too high. Check if the system pressure is low. Check whether the indoor/outdoor air inlet is blocked and whether the air volume at the tuyere is too small.
What does 'Liquid Deficiency Protection' mean on my AUX Q Series Air Conditioner?
If your AUX Air Conditioner displays 'Liquid Deficiency Protection', it indicates that the liquid volume of the system is less than 30%. Check the stop valve and turn it counterclockwise. Check whether the evaporator, condenser and connection pipe are damaged. Measure the temperature sensor with the multimeter.
What causes refrigeration overload protection in my AUX Q Series?
If your AUX Air Conditioner is experiencing refrigeration overload protection, it means the outdoor coil sensor is sensing excessive temperature. Check the coil sensor with a multimeter. Use a pressure gauge to detect system pressure. Observe whether the speed of AC motor is too low.
What to do if my AUX Q Series Air Conditioner displays error code E0 related to overcurrent protection?
The AUX Air Conditioner might display the E0 error code and stop running to protect itself if the main PCB detects that the system's working current exceeds the protection limit. To resolve this, verify that the live line passes through the current transformer. If it doesn't, correct the line's position and reboot the system for inspection. Also, use a current clamp to ensure the working current is within the normal range specified on the nameplate and check that the power supply voltage is within the normal operating range. If the current is too high but the voltage is normal, check the system for any blockages.
What to do if my AUX Q Series shows an Outdoor Unit DC motor error (3-core terminal motor)?
If your AUX Air Conditioner shows an Outdoor Unit DC motor error (3-core terminal motor), it is likely due to imbalanced current on the three lead wires of the driving motor. First, make sure to exclude any mechanical jam of the Outdoor Unit motor blades. Then, check if the terminal of the motor is not connected firmly and observe if the color order of the three lead wires is correct. If problems persist, prepare a matched Outdoor Unit main PCB before maintenance. If the motor returns to normal after replacing the main PCB, then it’s the main PCB problem.
What to do if my AUX Q Series Air Conditioner shows a 'High-pressure protection' error?
If your AUX Air Conditioner displays 'High-pressure protection' error, it means the high-pressure switch has been disconnected three times. Check whether the plug-in terminals are firmly connected. Use a multimeter to measure whether it is disconnected. Also, check the state of the High-pressure switch.
What does 'Outdoor EE error' mean on my AUX Q Series?
If your AUX Air Conditioner displays 'Outdoor EE error', it indicates a problem with the EE chip data format or that the EE chip is broken. The suggested solution is to replace the Outdoor Unit main PCB directly.
What does 'Indoor EE Failure' mean on my AUX Q Series?
If your AUX Air Conditioner displays 'Indoor EE Failure', it indicates a problem with the EE chip data format or that the EE chip is broken. The suggested solution is to replace the Indoor Unit main PCB directly.
What does it mean if my AUX Q Series Air Conditioner displays an Indoor Unit motor error (PG motor)?
If your AUX Air Conditioner's indoor unit motor (PG motor) is showing an error, it might be due to the PG motor not sending a speed feedback signal. Check whether the motor works for a while before the error appears. Disconnect the power supply and manually move the fan blade. Reconnect the drive wire and speed feedback wire. Ensure the plug-in terminal of speed feedback on the PCB is not loose. If problems persist, replace the motor with another PG motor; if the PCB still indicates an error, replace the Indoor Unit main PCB.
What does PFC protection error mean for my AUX Q Series?
If your AUX Air Conditioner is experiencing PFC protection error, it means that the PFC board is unable to perform power calibration due to overcurrent or overvoltage. Check if the supply voltage is unstable, and inspect the reactor itself for any damage. Test if the voltage supply on the PFC board is stable. As a test, try replacing the existing PFC board with one known to be in normal working condition.
