What to do if my AUX Air Conditioner shows an overcurrent protection error?
- A
  Amy RichmondAug 21, 2025
  If your AUX Air Conditioner displays the failure code E0, it indicates the air conditioner stopped running for protection due to the main PCB detecting that the working current of the system exceeds the upper limit. Check whether the live line passes through the current transformer; if not, lay the line accordingly and reboot for inspection. If the working current exceeds the range and the working voltage is normal, the system may be blocked and the air-conditioning may be overloaded, which needs to be checked according to the actual situation.

What to do if my AUX FREEDOM ASW-12-NFH3-E Air Conditioner has an Indoor Unit and Outdoor Unit communication error?
- M
  Ms. Diana SummersAug 31, 2025
  To troubleshoot a communication error between the Indoor and Outdoor Units of your AUX Air Conditioner, consider the following: * Check if the Outdoor Unit can power on and work. * Ensure the Indoor and Outdoor Units are matched and the phase sequence of connecting wires is correct. * Verify connecting wires are properly attached. Consider Indoor Unit main PCB replacement or Outdoor Unit main PCB replacement. * Confirm AC 220V can be delivered to the terminal block of the Outdoor Unit. * Check if the bridge rectifier and module panel generate DC 310V. * Verify the Outdoor Unit main PCB generates a low voltage power supply of DC 5V. * Check if the Outdoor Unit main PCB shows the status of periodical reset.

What does an Indoor EE Failure mean on my AUX Air Conditioner, and how can I fix it?

  Randall HansenSep 2, 2025
  If your AUX Air Conditioner displays an Indoor EE Failure, replace the Indoor Unit main PCB directly, as many parameters need to be preset for the running of the indoor unit of the air conditioner.

How do I resolve an Outdoor Unit DC motor error (3-core terminal motor) on my AUX FREEDOM ASW-12-NFH3-E Air Conditioner?
- L
  Laurie FrancisSep 3, 2025
  If your AUX Air Conditioner displays an Outdoor Unit DC motor error (3-core terminal motor), first exclude the possibility of mechanical jam of Outdoor Unit motor blades. Also, observe if the terminal of the motor is not connected firmly or the order of lead wires is correct. If the problem persists, replace the Outdoor Unit main PCB before maintenance; if the problem persists, replace the Outdoor DC motor. The main PCB will indicate “Outdoor Unit DC motor error” when it detects imbalanced current on the three lead wires of the driving motor.

What causes a module protection error in my AUX Air Conditioner?
- E
  Eddie GraySep 5, 2025
  If your AUX Air Conditioner displays a module protection error, check if the order of compressor wires is not correct, which makes the compressor rotate reversely. Also, check if the supply voltage is unstable and highly volatile. If “module protection error” will be indicated immediately after starting up, observe if there is any component destroyed. The power module is the part to directly drive the compressor to work.

What does PFC protection error mean on my AUX FREEDOM ASW-12-NFH3-E?
- J
  johngillespieSep 7, 2025
  If your AUX Air Conditioner displays a PFC protection error, check if the supply voltage is unstable and highly volatile or the voltage is too low (below AC 135V). The reactor is one of core parts of PFC, so check if the reactor itself is destroyed. If “PFC protection error” will be indicated immediately after starting up, observe if there is any component destroyed. The PFC board is a component of the inverter air conditioner for power factor correction and voltage boosting.

Why does my AUX FREEDOM ASW-12-NFH3-E Air Conditioner show a compressor out-of-step error?
- A
  Aaron GriffithSep 8, 2025
  If your AUX Air Conditioner displays a compressor out-of-step error, check if the order of compressor wires is not correct, which makes the compressor rotate reversely. Also, check if the supply voltage is unstable and highly volatile. If “compressor out-of-step error” will be indicated immediately after starting up, observe if there is any component destroyed. The module panel will constantly test the current of lead wires of the compressor and calculate the position of the rotator.

How do I troubleshoot an exhaust sensor error on my AUX FREEDOM ASW-12-NFH3-E?
- K
  Kevin ScottSep 12, 2025
  If your AUX Air Conditioner displays an exhaust sensor error, check if there is any evident resistance problem in the sensor. Check if the sensor wire or the sensor connecting wire is damaged. Check if the connecting terminal is connected firmly and whether the sensor is affected with damp. If there is no standard sensor at hand, exchange the exhaust sensor with the one beside it to see if the error changes. The Outdoor Unit main PCB will indicate “exhaust sensor error” and send it to the Indoor Unit main PCB when it detects short circuit or open circuit of the exhaust sensor.

What causes a compressor top head sensor error in my AUX FREEDOM ASW-12-NFH3-E?
- J
  jennifer62Sep 12, 2025
  If your AUX Air Conditioner displays a compressor top head sensor error, first check if the compressor top head temperature is too high (above 110°C) and causes action of the compressor top head sensor. After excluding the possibility of the system problem, please note that the temperature protection switch is closed normally. Check if the sensor wire or the sensor connecting wire is damaged and if the connecting terminal is connected firmly. Disconnect the power supply and short circuit a metal with the compressor top head terminal of the Outdoor Unit main PCB. The compressor top head sensor is a compressor top head temperature protection switch that keeps closed when the compressor temperature is normal.

How can I fix an Outdoor Unit temperature sensor error on my AUX FREEDOM ASW-12-NFH3-E Air Conditioner?
- A
  Alexander BradySep 13, 2025
  If your AUX Air Conditioner displays an Outdoor Unit temperature sensor error, check whether there’s resistance problem, short circuit or open circuit in the sensor; the resistance value shall be within a reasonable range (15KΩ under the temperature of 25°C). Check whether the sensor wire is broken and whether the terminal connectors are well fixed. Also check whether the sensor is affected with damp. In case no standard sensor is available at present, replace the Outdoor Unit temperature sensor with the other sensor asides, and then check whether the error still exists. The detection of short circuit or open circuit of Outdoor Unit temperature sensor during the inspection of Outdoor Unit main PCB causes this error.
