There are dozens of components that make your central air conditioner work. Without these parts, the air conditioner cannot work sufficiently, or at all. With so many parts that naturally decay over time and use, the air conditioner will eventually need repairs. However, many of these repairs can be avoided or stopped before the progression is extreme with routinely scheduled appointments that can catch the problems early on. Today, we at Air Supply Heating and Air Conditioning elaborate on the fundamentals of the central air conditioner fans and the common problems they experience in your Las Vegas Valley home.

Troubleshooting Why Central Air Conditioner Fans Are Not Working

The central air conditioner is equipped with two fans; one is located in the outside unit that blows over condenser coils in order to release heat from your home and the other is located in the inside unit that blows cool air for your home. If either of these fans experience any fault, the home cannot be cooled efficiently. Below is a list of why these fans commonly do not work properly or at all.
1) Capacitor. To provide power to your air conditioner’s fans, the capacitor stores up energy that is used. Your capacitor can go bad and stop working properly, for quite a few reasons, it will then force one of your system’s fans to stop spinning. More often than not, a bad capacitor will need a professional replacement.
2) Contactor. In order to control the compressor as well as the condenser fan motor, an air conditioner’s contactor is a switch in which electricity flows in and out. Restricting the outside unit’s fan from functioning properly, it is common for the contactor to wear down over time. A professional HVAC contractor can get the contractor replaced safely and easily.
3) Burnt Out Motor. Fans can burn out when they undergo too much stress, especially being prone to wear and tear. They are even more vulnerable to excessive wear when the air conditioning unit is not properly maintained. Depending on the age and condition of your system, a bad fan motor is a more serious issue that will either require professional repairs or a system replacement.
4) Broken or Loose Belt. The belt can get loose or break and cause the fan to stop spinning properly in older systems with belt-powered fan. Where this issue can be repaired, it can also be an indication that a new air conditioning unit is in order since you likely have an older, less efficient unit.
5) Power is Not Being Received to the Unit. A power issue can be at fault as opposed to air conditioner fan problems being the fault of the fan’s assembly. The air conditioner can be forced to shut down, for example, if the various parts of your air conditioner can overheat and trip your circuit breaker. You can flip the switch at your circuit breaker back on should this be the cause, however if it continually occurs, you should have a professional inspect the unit as to the underlying cause.
6) Air Filter Blockage. The air that it blows will be completely blocked if your air filter is severely clogged and your indoor fan is working properly. Check your air filter and replace it if it’s dirty, particularly if it sounds like your fan is working but you don’t feel any air in your home.
