Whether it's not spinning at all or is displaying sluggish movements, an AC fan malfunction can turn your home into a summertime nightmare. According to the professionals at Hunter Heating & Air Conditioning in High Point, NC, it's important to diagnose and evaluate the level of seriousness of the breakdown before coming up with a game plan. Below, the HVAC contractors explain how to pinpoint the source of the fan malfunction as well as the next steps you need to take.
How to Determine the Cause of an AC Fan Malfunction
If you're lucky, the problem is simply the result of debris blocking the fan's movement. Make sure the system is off and check the compressor on the exterior of your home for visible blockage. Small sticks are the most common culprit, but a buildup of decomposing leaves or mud can also cause havoc. At this time, you should also look for physical damage to the fan, such as broken or chipped blades.
According to the HVAC contractors, motor, thermostat, and voltage issues are also common causes of fan breakdowns. If the fan is working correctly but kicks on and off at random intervals, it's most likely an electrical or thermostat problem. To identify a motor issue, turn the unit off and use a stick or metal rod to see if the fan will rotate manually. Free movement is a sign that the motor is the cause, and if there's a slight teeter or sway in the movement, it's most likely that the bearing is damaged.
What You Should Do Once You've Identified the Problem
Sometimes, flipping the breaker to the AC unit is enough to fix the problem, especially if it's related to a thermostat issue. However, you should also take advantage of the unit being off and clean the area around the fan. Remove any debris that could inhibit the fan's movement, and go ahead and clear out grass, foliage, and twigs surrounding the unit's perimeter. After you've completed these tasks, flip the breaker back to “on” and reevaluate its operating level.
As a novice, it's challenging to accurately diagnose an HVAC malfunction. If you still experience the issue after the two steps above or suspect the problem is a result of the motor or wiring issues, contact your HVAC contractor. They'll complete more thorough diagnostic testing to pinpoint the issue and suggest the appropriate air conditioner repair.
