Your central A/C unit is critical to the comfort of your home. If it isn’t working right, your home can become hot quite fast, and you’ll have to troubleshoot the issue. Today we’re going to talk about a common issue: your A/C fan not spinning.
Your central cooling system has two fans: one situated inside that drives cool air into your house, and one located outside that moves over condenser coils to get heat out of your house’s air. If there are issues with one of these fans, your A/C won’t be able to cool your home correctly. Here are a few reasons for an AC fan not spinning and what you need to do.
Reasons Why Your AC Fan Is Not Spinning
Broken or loose belt. In older units with belt-powered fans, the belt can break or get loose and make the fan stop spinning correctly. This can be repaired, but it’s usually a good indication that it’s time for a new cooling unit.
Contactor problems. An A/C contactor is an electrical switch that regulates the condenser fan motor and the compressor. It’s typical for the contactor to break down which stops the outside fan from accurately working. This is another part that has to be replaced by a professional HVAC repair contractor.
Burnt out motor. Fan motors are victims of plenty of wear and tear. They burn out due to too much stress. This is particularly true for cooling systems that are not correctly maintained. A bad fan motor is a serious problem that will necessitate a unit replacement professional air conditioning repairs based on the condition and age of your unit.
Capacitor issues. A capacitor collects energy that is used to give power to your air conditioner fans. For numerous reasons, your capacitor can malfunction and quit working correctly which will make one of your unit’s fans stop spinning. Usually, a bad capacitor needs to be replaced by a Rochester air conditioning professional.
It’s imperative to note that many central A/C fan problems can be stopped by getting a yearly air conditioner tune-up. The price you pay for an annual assessment will pay off tremendously in the future by ending possible costly A/C fan repairs.
