An air conditioner has two fans that are crucial for its operation: the blower fan, housed in the indoor cabinet, which sends air from the return vents through the evaporator coil to cool it off and then out into the ventilation system; and the outdoor fan, which draws air across the condenser coil to release heat and then vent it outside. If a malfunction occurs in the motors that run either fan, it will result in a loss of cooling power and a drop in airflow.
When you notice issues with the fans, whether its loud noises or no noise at all, you need to have repair technicians come to your home to investigate the cause and fix it. Often the problem lies in the motors, which can sometimes be repaired and other times will require replacement. There are a number of different problems that can afflict an AC fan motor, but if you trust to the skill of the Glendale air conditioning specialists at JW Heating & Air, you will have the fan motor trouble remedied in no time.
Here are some common AC fan motor problems
- Broken fan belt: This is only an issue with older air conditioners. (Newer models use direct motors that do not use a fan belt.) A fan belt can sustain damage and wear down to the point that it will snap apart. This will not only cause the fan to stop moving, but it will also risk a loose belt striking against other components and damaging them. Loud striking noises will alert you to this problem so you can call for repairs.
- Dirt or loss of lubrication: If too much dirt enters the air conditioner’s cabinet, such as getting through the air filter of the indoor cabinet or infiltrating the grill of the outdoor cabinet, the dust and dirt along the motors moving parts will make it start to overwork and can eventually cause it to become frozen in place—or worse, overheat, which will require that the motor be replaced. You should have regular maintenance to check on the motors and clean them every year to help avoid these problems.
- Failing capacitors: The motor needs two capacitors to run it. The first capacitor sends the voltage to start the motor up, and the second sends regular bursts of voltage to keep it running. If the capacitors start to fail, the motor will begin struggling to come on and eventually won’t come on at all or will quickly shut off. The capacitors will need to have a professional replace them.
Any reduction in airflow or cooling capacity from an AC needs the work of skilled technicians to find out the cause and what can be done to fix it.
