Failed Capacitor: An AC Problem on Super Hot Days

Russell's Heating and Air Conditioning	Russell's Heating and Air ConditioningThe serious summer scorcher days are the baseline of what we expect here in the deserts of Southern California. Our air conditioners run steadily through most days, and sometimes into the nights. That amount of labor places immense strain on any air conditioning unit, which can lead to parts breaking down.

But the heat itself can have an effect on an air conditioner as well–aside from the amount of work the AC system does. One problem that our AC repair technicians encounter when the temperatures soar above 100°F is failed capacitors.

The Capacitor vs. The Heat

Capacitors are electrical components that send electrical voltage to the motors. Start capacitors get motors running, and run capacitors keep them running.

Capacitors are sensitive to high temperatures: if exposed to too much heat, a capacitor will start to lose its ability to hold an electrical charge (in other words, its capacity to hold a charge), and this leads to capacitor failure. If a start capacitor fails, a motor will not be able to start up. If a run capacitor fails, a motor will only run for brief time before shutting off.

Capacitors give off signs they’re failing. A clicking sound from an air conditioner when it starts up often indicates a dying capacitor. A hard-starting air conditioner, where the system struggles each time it starts ups, is also an indication of possible capacitor problems. (There are other causes for hard-starting, so always have technicians look into it.)

If a capacitor fails, it will need to be replaced. This is a job for professionals only: if an amateur puts in the wrong type of capacitor, it can cause serious damage to the motor.
