Fans are an essential part of the operation of an air conditioning system. Without working fans, no air would move across the evaporator and condenser coil to exchange heat, nor would any air enter the ventilation shafts and reach the rooms of a house.
Fan problems due to issues with the blades or the motors can sometimes impair AC operation; if you hear loud striking sounds from either cabinet, detect a drop in cooling power, or notice no noise coming from one of the fans at all, you may have fan motor or fan blade troubles.
For any fan repair needs in an AC, you need to have qualified professionals on the job. Call JW Heating and Air for these repairs for your air conditioning in Pasadena, CA. Many of our technicians are NATE-certified and can deliver fast and excellent repairs that will restore the valuable cool interior to your home.
Burnt-out fan motors
Fans in air conditioners used to connect to the motors through a fan belt. Today, most fans run from a direct motor. These motors are susceptible to wearing down due to stress, dust along their moving parts, or a lack of lubrication, and this will lead to the unit overheating. An overheated motor will burn out—fusing the wires inside its casing—and this will require that a professional replace the motor. If you hear a screeching or groaning sound inside the cabinet, it may be motor problems: call for technicians right away.
Bent fan blades
This is an issue that often afflicts the outdoor fan, which is more exposed to elements such as rocks and sticks that might infiltrate the cabinet and damage the blades. Bent blades are a serious issue, since they will cause the fan to begin clanging against the outside of the fan assembly. If not stopped soon, it will cause even more damage inside the cabinet. Turn off the system and call for repairs.
Stuck fan motor relays
The relays on a fan motor control whether voltage flows into the unit. When a relay is open, voltage moves through and the motor runs; when it’s closed, the voltage stops and the motor ceases running. The relays can break or get stuck in one position or another, which can lead to a fan that won’t start running or one that won’t stop. Technicians will investigate and find out what is causing the problem. Relays can be either fixed or replaced.
