8.2: Capacitors and Capacitance
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...
What is a Furnace Capacitor and How to Tell If It''s Bad?
The job of the start capacitor is to store that extra power. When the thermostat and control board sends a request to start the motor turning, the capacitor sends that burst of power to get it spinning. A capacitor is a sealed unit, typically shaped like a small can, and can only be replaced, not repaired. Signs of a Bad Furnace Capacitor

Best HVAC Capacitor Guide: How to Find the Right One
Even though capacitors aren''t the first thing that comes to mind when HVAC systems are mentioned, using an AC, a furnace, or a heat pump without a capacitor isn''t possible. All HVAC systems come with built-in capacitors, and if one or more of the unit''s capacitors fail, the best course of action is to replace them with an identical model.
