    Why is my Acson A5WMY Air Conditioner not cooling enough?
    • M
      Mr. Edgar Simmons DDSAug 9, 2025
      If your Acson Air Conditioner is running but not providing sufficient cooling, there are several potential causes. Begin by checking the thermostat setting and ensure it is set to a lower temperature. Make sure that there are no obstructions blocking the air inlet or outlet of the unit; if there are, remove them. For other potential problems such as a dirty condenser coil, insufficient refrigerant, improper water flow rate, or contaminated water in the system, contact your local dealer.

      If your Acson Air Conditioner is blowing air, but it's not cooling effectively, consider these possible causes. First, check the thermostat to ensure it's properly adjusted to a cooler setting, taking into account the inlet temperature. Clean the filter if it's filled with dust and dirt. Remove any obstacles blocking the air inlet and outlet. Finally, make sure that windows and doors are closed to prevent warm air from entering the room.

      If the compressor of your Acson Air Conditioner doesn't start, there could be several reasons. First, check the power supply to ensure the unit is receiving power. Then, inspect the fuses and circuit breakers, replacing any blown fuses or resetting tripped breakers after correcting the fault. Also, check for loose wires and tighten any loose terminal screws. If a safety switch has tripped, determine the cause and correct it to restart the unit. If these steps don't resolve the issue, the contactor or coil might be defective and require repair or replacement. If the compressor is faulty, contact your local dealer.

    Why Acson A5WMY fan runs but compressor won't?
    • S
      Sean WeeksSep 1, 2025
      If the fan of your Acson Air Conditioner is running, but the compressor isn't, it could be due to a couple of reasons. First, check the thermostat setting; if it's set too high, decrease the set temperature for cooling. Also, if the room temperature is excessively low, the unit might be out of its temperature control range, preventing the compressor from running.
