There are many components to an HVAC system that work together to keep your home cool and comfortable when it is hot outside. When one component fails, the entire air conditioning system will suffer. One major component that undergoes a lot of stress during the warmer season is the air conditioner’s fan. The fan and or its motor is one of the first components to break down and require repair or replacement in the life of an HVAC system. Air Supply Heating & Air Conditioning will share the common symptoms of a failing fan as well as its motor and when to seek professional HVAC services.

AC Fan Does Not Start

When the fan will not turn on or start, the motor has either died completely or the fan motor’s capacitor is broken or has gotten stuck. If the capacitor breaks down or is stuck to the off position, then the motor will not receive any power. Replacing a capacitor is a much faster and easier fix than replacing the motor. An HVAC technician will be able to determine why the fan will not start.

AC Fan Keeps Running

You may have the opposite problem where the fan will not stop at all. In this situation, it could either be the thermostat is set to the “on” setting. Make sure to check your thermostat setting first. If the thermostat is set to “auto” then the problem may be the capacitor again, but this time the capacitor is stuck to the on position and isn’t cutting off the power to the fan motor.

AC Fan is Weak with Blades Turning Slowly

When the fan blades are turning, but very slowly, this is a problem. In most situations this is a sign of neglect. The fan and its motor needs to be clean, and the blades and other moving parts lubricated. The motor is stressed out to the point the motor is finally burning out and dying. You will need to replace the motor and have the fan cleaned and lubricated.

AC Fan Making Loud Noise

A fan and its motor can make a few different odd noises depending on the problem. When you hear a rattling noise when the condenser turns on there may be a loose screw or bolt. A humming or buzzing noise often is the result of an electrical problem. Do not ignore odd noises. In such cases, be sure to have the condenser unit checked and inspected.

AC Fan Motor Runs Intermittently

When the fan motor will start up but then suddenly shut down, this is a common sign the fan motor is overheating. There could be a number of reasons why the fan motor is overheating. Have a technician inspect the unit to determine what is causing the overheating.

Air is On But Not Cooling

When you feel only warm air blowing throughout the home there could be a ton of different reasons why. You may have a refrigerant leak, leak in the air duct, faulty evaporator system and more. One of the culprits to why you have warm air blowing is the condenser’s fan has failed.
