5 Reasons Your AC Fan Is Not Working

Reasons Your AC Fan Is Not Working

The indoor fan of an AC is more than just a way for the air conditioner to circulate cooled air throughout the home. It is also how the air conditioner cools hot air coming in from the interiors by moving it over the evaporator coils. There is no way to supply any air around the home without a running fan.

If your AC fan is not working, it is probably time to contact professionals for service. Understandably, you cannot go long without an air conditioning system for your home during the sweltering late summer days in St. Louis. However, the issue could be a minor oversight. The five most typical causes of a failing central air conditioner fan are mentioned below.

Why Your AC Fan is Not Working

What to Do if Your AC Fan Is Not Working

Here are the five most likely reasons your AC fan is not working.

  • Tripped Circuit Breaker: When your AC fan stops working, go to your home’s electrical panel before doing anything else. Check the air conditioner’s circuit. If it is tripped, check the fan again after resetting it. The fan motor can sometimes overload the circuit, particularly if the HVAC filter is blocked. Contact a professional if the circuit breaker keeps tripping.
  • Motor Burnout: The blower fan motor is one of the most hardworking parts of an AC unit, as it operates not only when the air conditioner is turned on but even when the compressor is turned off intermittently. As such, the motor is likely to burn out if it is overworked. The wiring in the casing can fuse if the motor overheats, and the motor must be replaced in this case. You may even have to replace the entire system if the AC is older than ten years.
  • Problem with the Contactor: This is a distinct but minor issue with the motor of the blower fan. The power supply to the motor is opened and closed by an electrical switch. However, it may not be able to fully close if it gets dirty over time, and the fan will not turn on when it is expected to. The contactor can be cleaned or replaced by professionals.
  • Failed Capacitors: The capacitors operate as temporary batteries, regulating the voltage flow to the motor. The motor is started by one capacitor and is kept running by the other. Capacitors degrade with time and if they fail, they can be the reason for your AC fan not working. If this is the case, they must be changed by a professional.
  • Damaged Fan Due to Debris or Loose Parts: Debris in the housing might cause the fan to come loose or cause damage to the fan blades. This can happen when the air filter has become so clogged that it expands and allows items to slip around the sides or if the unit is run without a filter present. If you heard the fan rattling and banging before it stopped functioning, this is likely the cause. Only a professional can fix this for you.
