AC unit humming but not turning on

At first, you may not even notice it. You go about your day, doing tasks, resting—whatever it is you do. Nothing seems amiss. Then, you observe that it feels a little warmer than usual. Perhaps, you hear the air blowing through the vents and think the excess heat is just your imagination. A little later, warm turns into uncomfortably toasty. Next, you hover your hand over the vents and feel nothing but hot air. Finally, you go outside to listen to your unit. There, you realize that you have an AC unit humming but not turning on properly.

If this sounds somewhat familiar. Keep reading.

Why is My AC Unit Humming but Not Turning on Properly?

An AC unit humming but not turning on properly can signal several things. First, you may have a faulty capacitor. The capacitor is the small metallic object on the side of your outdoor unit. You can kind of think of it like a battery that boosts your air conditioner. When the thermostat clicks on, the capacitor kick-starts the compressor and fans. If the capacitor has gone bad, the fans don’t have enough of a jolt to move.

However, there is a short-term fix. Carefully, use a long, thin object such as a sturdy stick or screwdriver to gently push the fan into motion. Typically, once it gets moving cool air will begin blowing through your vents. Keep in mind, this is a quick fix. You still need to replace your capacitor to prevent motor burn-out. Speaking of which, if this technique doesn’t work, you may have a bad fan motor.
