Unfortunately, I still run into problems from time to time and I am sure that all of you do, which is one of the reasons I decided to build this website. Check out these posts for more information about keeping your system working beautifully, even if you aren't naturally good at fixing things.

An AC Repair Technician May Need To Replace The Capacitor When Your Condenser Fan Doesn't Start

Herbert Franklin

A capacitor is a small part that can cause big problems for your air conditioner when it breaks down. One sign of a bad capacitor is when a humming noise comes from the condenser. Another sign is when the condenser fan doesn't start up. Here's a look at how a malfunctioning capacitor might cause harm to your air conditioner and how an AC repair technician can fix the problem.

The Capacitor Sends Power To The Fan Motor

When your AC starts up, the capacitor sends an extra boost of energy to the fan motor so the motor can start from a full stop. If the capacitor is bad and can't send extra power to the fan motor, the motor may strain and burn out, or the motor may just not start at all. Either way, the condenser fan won't be able to run, and that's not a good thing.

The Fan Blows Heat Out Of The Condenser

It gets hot inside the condenser even though it has a grille on top and vents on the sides. The fan needs to run to blow heat out of the condenser so the parts don't overheat. If the fan isn't working, heat can build up and affect the compressor. Heat can also build up around the refrigerant lines and keep the refrigerant from working as well as it should.

If the refrigerant can't cool your house like it's supposed to, your AC has to run longer, and that increases your power bill. The biggest problem is the threat to the compressor. The compressor is one of the more costly parts in your air conditioner, and if it burns out, you'll have an expensive repair bill to deal with since your AC won't work at all with a bad compressor.

The AC Repair Tech Can Replace The Capacitor

The best action is to have the capacitor replaced before it damages the fan motor or compressor. Capacitors aren't repaired, they have to be replaced with new ones. The AC repair technician has to find an exact match and then pull the old one out and put the new one in. The capacitor is right behind the access panel, so it's easy to reach and pull out. It is usually inside a bracket and connected with just a few wires, so replacing it is an easy job.

Replacing a bad capacitor is an easy AC repair when compared to replacing a motor or compressor, so if you hear your AC making odd sounds, or if you notice the fan doesn't start up, call an AC repair company so they can send a technician to your home as soon as possible.
