What does Outdoor EE error mean on my AUX FREEDOM, and how can I resolve it?
If your AUX Air Conditioner displays an Outdoor EE error, replace the Outdoor Unit main PCB directly, as many parameters need to be preset for the running of the Outdoor Unit of the air conditioner.
What to do if my AUX FREEDOM Air Conditioner has an Indoor Unit and Outdoor Unit communication error?
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?
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 Air Conditioner?
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 FREEDOM?
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 Air Conditioner?
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.
How to fix an Indoor Unit motor error (DC motor) in my AUX wall mounted Air Conditioner?
If your AUX wall mounted Air Conditioner indicates an Indoor Unit motor error (DC motor), and the Indoor Unit motor of some highly energy efficient models is DC motor using a green plug, check whether the motor accelerates to extremely high speed before the error occurs. If it can work for a period, the reason of mechanical jam can be excluded. Plug and unplug the terminal of the DC motor again to exclude any motor error due to connector loosening, and pull the terminal slightly for inspection if necessary. Replace the motor in the faulted air conditioner with other DC motor to plug in the Indoor Unit main PCB (do not fix it with the fan for the time being), if the main PCB still indicates “DC motor error”, then replace the Indoor Unit main PCB; if the error disappears, replace the DC moto...
How to troubleshoot an Indoor Unit temperature sensor error on my AUX FREEDOM Air Conditioner?
If your AUX Air Conditioner is showing an Indoor Unit temperature sensor error, check the following: * Check if there’s a 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 for frequency conversion machine). * Check whether the sensor wire is broken. * Check whether the terminal connectors are well fixed; check whether the weld between the terminal and the main PCB is loose, and pull the terminal slightly for inspection if necessary. * Check whether the sensor is affected with damp. If no standard sensor is available, replace the Indoor Unit temperature sensor with another sensor, and then check whether the error still exists; if the error disappears, replace the sensor; if t...
How do I fix a communication error between the Outdoor Unit main PCB and module panel on my AUX Air Conditioner?
If your AUX Air Conditioner has a communication error between the Outdoor Unit main PCB and module panel, check if the communication connection line between the module panel and main control panel gets loose. Measure and check with a multimeter if the power from the Outdoor Unit main PCB is normal. The maintenance personnel shall replace the module panel of the faulted air conditioner with a regular module panel taken with him. Only the models with the module panels separated with the Outdoor Unit main PCBs may have this error.
How can I fix an Outdoor Unit temperature sensor error on my AUX FREEDOM Air Conditioner?
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.
