How To Remedy Issues In Your Central Air Conditioning
In the desert climate of the Coachella Valley, cooling season is most of the year. That means your central air conditioning system is vital to your home comfort. If it isn’t working correctly, your house can become dangerously hot quite quickly, and you’ll need to troubleshoot the problem.
Your central air conditioner has two fans: one located inside which blows cool air into your home, and one located outside which blows over condenser coils in order to release heat from your home’s air. If there are problems with either of these fans, your air conditioner will not be able to cool your home properly. Let’s look at some likely reasons for a malfunctioning central air conditioner fan, and what you can do to resolve the problem!
5 Common Reasons Why Your Central Air Conditioner Fan Is Not Working
- Capacitor problems. A capacitor stores up energy that provides power to your air conditioner’s fans. However, your capacitor can go bad for various reasons and stop working properly, which will force one of your system’s fans to stop spinning. Often a bad capacitor will need to be replaced by a professional.
- Contactor problems. An air conditioner contactor is an electrical switch that controls the compressor and condenser fan motor. It is common for the contactor to go bad over time, which restricts the outside fan from working properly. This is another part that must be repaired by a professional HVAC contractor.
- Burnt out motor. Fan motors go through a lot of wear and tear, and can burn out when they undergo too much stress. This is especially true for air conditioners that are not properly maintained. A bad fan motor is a serious issue that will either require professional repairs or a system replacement, depending on the age and condition of your system.
- Loose or broken belt. In older systems with belt-powered fans, the belt can become loose or break and cause the fan to stop spinning properly. This can be repaired, but it’s often a good sign that it’s time for a new air conditioner.
- Unit not receiving power. Some air conditioner fan problems might be a power issue, rather than anything to do with the fan’s assembly. Various parts of your air conditioner can overheat and trip your circuit breaker, forcing your air conditioner to shut down. If this is the case, you can flip the switch at your circuit breaker back on. However; repeated power issues should be looked at by a professional.
