Imagine it’s a scorching hot summer day and you’re training for a 5k. You’ve just finished that final, grueling leg of your run as you turn into your neighborhood. Despite its best efforts, the sweat dripping down your face isn’t doing much to cool you off. The beads barely have a chance to seep out of your pores before they’re boiled off by the heat of the sun. Oh, and speaking of moisture, you’ve just consumed the last drop of water in your water bottle.
What you want more than anything else at this moment — even more than one more lifesaving gulp of refreshing, cold water in your bottle — is to feel the cool embrace of your air-conditioned home.
But then you step inside, and you’re met with warm, stagnant air instead of that breeze you’ve been fantasizing about for the last 30 minutes. In a panic, you check your AC unit, and there it is — the telltale hum of the system running, but the AC fan is not spinning.
Frustrating, right? At Eck Services, we’re not a fan of these situations either. Here’s what may have caused the issue and what you can do to get relief in those desperate scenarios when your AC fan is not working.
How Air Conditioner Fans Work
Before we dive into the potential causes, let’s quickly review how AC fans work.
Your air conditioning system typically has two main fans:
- The indoor blower fan: This is the fan inside your home, responsible for circulating the air that’s been cooled by refrigerant coils through your ductwork and into your living spaces.
- The outdoor condenser fan: Located in the unit attached to your home’s exterior, this fan’s role is to remove heat from your house and release it outdoors.
When everything’s running smoothly, these fans work together to keep your home cool and comfortable. But if even one of them stops spinning, it can throw a wrench into the whole operation.
Reasons Why Your AC Fan is Not Spinning
When your fan is not spinning on your AC unit, it can be due to many factors:
Malfunctioning AC Capacitor
Think of the capacitor as your AC’s battery. It provides the initial jolt of electricity to start the fan motor and keeps it running. Over time, capacitors can wear out, leaving your fan motor without the power it needs to spin.
Power Issues
Wouldn’t it be great if we could just fix a broken AC unit with the flip of a switch? If there’s a power issue, that may be all it takes. Inspect your circuit breaker box to see if the breaker tripped. If it has, you may simply need to flip the corresponding switch.
Malfunctioning AC Fan Motor
Sometimes, the fan motor itself is the problem. Years of use, lack of maintenance, or electrical issues can cause the motor to burn out, leaving you with a fan that hums but won’t move.
Electrical Wiring Problems
From tripped circuit breakers to loose wiring, electrical issues can prevent your fan from spinning. While the system might still have enough power to create a hum, it may not be enough to turn the fan.
Cracked Fan Belt
If you have an older AC unit, it might use a belt system to turn the fan. These belts can wear out or break over time, leaving your fan motionless.
Dirty Bearings
The bearings in your fan motor allow it to spin smoothly. When they wear out, it creates excess friction, making it difficult or impossible for the fan to turn.
Compressor Contactor Issues
The compressor contactor helps control the flow of electricity to your AC components. If it’s stuck or damaged, it might not send power to your fan motor.
