  If your AC Pro Air Conditioner isn't starting, first, ensure there isn't a power outage. If power is available, inspect the power supply circuit and confirm the power plug is securely connected. Also, verify the wiring between the indoor and outdoor units is correct per the circuit diagram and that all wiring terminals are firmly connected. Check if the air conditioner is reliably grounded and the wiring is correct. Inspect the power cord for damage and replace if needed. Ensure the air switch is appropriate for the unit. Finally, try replacing the remote controller batteries or repairing/replacing the controller.

Why is my AC Pro AWHD(30)ND3G/O not cooling or heating properly?

  If your AC Pro Air Conditioner isn't cooling (or heating) well, start by adjusting the set temperature. Increase the fan speed of the indoor unit to medium or high. Clean the indoor unit's filter. Ensure proper installation positions for both indoor and outdoor units, including rain and sun protection for the outdoor unit. If refrigerant is leaking, identify and fix the leak, then add more refrigerant. If these steps don't resolve the issue, there may be a malfunction of 4-way valve or capillary. Also make sure that the flow volume of valve is sufficient. For malfunctions of horizontal louver, the IDU fan motor, the ODU fan motor, or the compressor, consult the corresponding maintenance instructions.

  If your AC Pro Air Conditioner compressor isn't operating, ensure the wiring is correctly connected and all terminals are secure, following the wiring diagram. Replace the compressor capacitor if it's damaged. If the power voltage is too low or high, consider installing a voltage regulator. If the compressor coil is burnt out or the cylinder is blocked, the compressor may need repair or replacement.

  If the horizontal louver on your AC Pro Air Conditioner isn't swinging, check the wire connections according to the wiring diagram to ensure they are correct and firmly connected. If the wiring is correct, the stepping motor may be damaged and require repair or replacement. If the issue persists, the main board might be damaged and need replacement with the same model.

  If the ODU fan motor on your AC Pro Air Conditioner isn't operating, first check the wire connections to ensure they are correct and firmly connected, referring to the wiring diagram. If the wiring is correct, the fan's capacitor may be damaged and need replacing. If the power voltage is too low or high, consider installing a voltage regulator. If the motor is damaged, change the compressor oil and refrigerant; if this doesn't help, replace the compressor.

Why does my AC Pro AWHD(30)ND3G/O make abnormal sounds and vibrations?
- L

  Normal operation of the AC Pro Air Conditioner can produce sounds as the unit turns on or off due to panel expansion or refrigerant flow; these sounds should diminish quickly. If there are foreign objects inside the indoor or outdoor unit, remove them. Adjust the position of all parts inside the unit, tighten screws, and apply damping plaster between connected parts. If there is a short circuit inside the magnetic coil, replace it. If the compressor shakes abnormally, adjust the support foot mat and tighten the bolts. If there's an unusual sound inside the compressor, and too much refrigerant was added during maintenance, reduce the refrigerant level. For other compressor issues, replace the compressor.
