What Does The Capacitor In My Furnace Do?

Furance RepairThe more you know about how your heater functions, the better prepared you’ll be to point the repairman in the right direction when fixing a problem. For example, you might have heard the term “capacitor” in relation to your furnace. But what exactly does  the capacitor in your furnace do?

Capacitors are a part of the fan motor in your furnace. They are generally divided into two types, both of which provide electricity to the furnace apparatus at key times. The first kind of capacitor is a start capacitor, which helps the motor start up when you first turn on your heater.

There is also a run capacitor: used in furnaces, HVAC systems and AC units of all varieties. They provide a steady supply of electricity to the fan motors (used to help the blowers move hot air through your system).

Obviously, both types of capacitor need to be running smoothly in order for your furnace to function. Otherwise, your furnace won’t be able to heat your home. Electrical problems can usually be hunted down and corrected by a trained professional armed with a multimeter or similar piece of equipment.
