Troubleshooting Problems With Your AC Fan
Fans are an essential part of any AC system. After all, it’s fans that ensure airflow and proper heat release. But like any component of a household appliance, fans can experience problems that can lead to additional system issues.
Quickly taking note of any AC fan issues is the key to preventing further problems and complications down the line. We will discuss the signs that can indicate issues with an AC fan.
Warning signs
Warning signs with AC fans can be tricky. Sometimes, there might seem to be an AC fan issue when none exists. Other times, a homeowner might overlook an issue, which can then further lead to other complications. Here are some signs of potential fan problems.
First, take note of the sound the AC makes. A clunking sound can be indicative of a bent or loose fan. The blade is most likely hitting the inside part of the AC unit, which can, over time, damage the fan and whatever it might be hitting. A screeching sound, on the other hand, is indicative of a worn-out fan belt. Due to the lack of a proper strap, the fan will wear out and cause performance issues over time.
Speaking of performance, that’s another way to tell that your AC fan is experiencing problems. For instance, a decrease in the airflow coming from the unit into the home is often a sign of a malfunctioning fan. Alternatively, if there is too much warm air blowing inside, this can represent an issue with the fan not turning at all. Finally, if an AC starts developing ice, it’s a sign that there may be a fan failure issue.
Common fan problems
Although they may seem trivial and straightforward—just a few blades and a plastic center—fans are complex units. For instance, AC fans include electrical wiring and a motor as well. Here are a few common fan problem areas.
Motor issues
If a fan’s motor burns out, overheating will start occurring. But since we’re talking about electric fans, a simple motor replacement will do the trick here. Unless you’re an expert, do not perform this type of replacement as a DIY project. A professional service should be able to provide quick, reliable help with all fan and AC problems.
Electrical issues
Sometimes, the problem may not be the motor itself—it might be an issue with the wiring. If the wires become loose and disconnect, they can damage the AC fan.
Fan blades issues
Although most AC fan blades are metal, they can still break and bend. If they are damaged, they can operate irregularly and destroy other components inside the AC.
