    1. The fan does not turn when the air conditioner is switched on

    If the AC fan does not start even when it is switched on, it may be a clear sign that the air conditioner heat pump fan motor is faulty. When the air conditioner runs without the fan circulating air, it will eventually cause the evaporator coil to freeze up. Once this happens, your air conditioning unit will be at risk of more serious damage. Please turn off the air conditioner and call a technician.

     

    2. Fan continues to run even when AC power is turned off

    The fan works normally, but the blades spin very slowly. A slowly rotating fan will produce a weak airflow. If your AC offers a different fan setting, check that it is set to low speed. If this is not the case, it may mean that the air conditioner heat pump fan motor is faulty.

     

    3. The fan is on but spinning slowly

    The fan does not work, even if the blades are spinning very slowly. A slowly rotating fan produces a weak airflow. If your AC power supply offers a different fan setting, check that it is set to low speed. If this is not the case, it may mean that the motor bearings must be oiled or that the capacitor is faulty.

     

    4. Intermittent fan operation

    When the fan runs intermittently, there are two possible causes for the problem. Firstly, it is possible that the air conditioner heat pump fan motor has overheated, causing it to stop running. Alternatively, loose wires, connections or a short circuit in the motor winding could be the culprit.

     

    Any electrical-related problems should only be solved by a professional. For example, never attempt to operate a fan motor when you suspect an electrical problem. This can be dangerous and is best left to a trained technician or electrician.

     

    5. Condenser unit rattling or humming when the fan is turned on

    There is more than one possible cause of air conditioning noise.

    If you hear a loud rattling noise, this could be a minor problem such as loose stones or debris in the condensing unit.

    Loose or unbalanced fan blades hitting the side of the fan housing unit may also cause a rattling sound.

    If you don't see anything stuck in the condensing unit and the fan blades turn freely and smoothly, it could be the fan motor.

    If you hear a humming sound, this is another sign that the air conditioner heat pump fan motor is coming to the end of its life.
