Scorching outdoor temps plus the heat of the motor can overwhelm a capacitor and cause it to fail. They can also suffer damage from high temperatures or high voltage. Like batteries, capacitors lose the ability to hold a charge over time. Disposing of a capacitor that hasn’t been discharged can even cause a fire.Īfter the bad capacitor has been safely removed, replacement is a matter of selecting the right replacement and attaching the wires correctly. Otherwise, touching two capacitor terminals at the same time will cause an electric shock. The power to the AC unit must be shut down before opening the service panel, and the capacitor itself discharged of stored energy before it can be removed. The replacement process involves dealing with high voltage, and there is a risk for serious or even deadly electric shock if not done safely and properly. It’s possible, but not recommended unless you already have experience working with the electrical components of your AC unit. So, if the capacitor attached to your fan motor is bad, the fan won’t start spinning. It needs that extra boost from a start capacitor. It takes much more energy to get the outdoor fan going than it does to keep it running. Capacitors send an electrical jolt to start a motor (a “start capacitor”) or to keep one running (a “run capacitor.”) In an air conditioning system, capacitors work with three different motors: the compressor, the indoor blower fan, and outdoor fan. What does an AC capacitor do?Ī capacitor is a small, cylindrical object that stores energy-similar to a battery. It is not difficult to fix, but most homeowners hire a professional for this task. If your fan looks clean and moves freely, you may have a bad capacitor. The AC fan and internal components can be very dangerous. Do not attempt to open the unit or insert objects into th fan unless you are qualified to do so. Cleaning the unit, or removing debris may fix the issue. ![]() If there is an exceptional amount of dirt or debris around the fan axle it may not be able to move. If it’s buzzing, but the fan is not spinning, you may have one of two issues.įirst, If the fan on your outside unit is not spinning, do a visual inspection to ensure it is not jammed. If your air conditioner is not working, check the fan on the outside unit. ![]()
