The capacitor, sometimes called a "run capacitor," starts the condenser and the fan in the outdoor unit. If the capacitor fails, the air conditioner won''t run. What are the signs of a failed AC capacitor or contactor? The most common sign of a failed capacitor is a clicking sound followed by a buzz or hum.
The capacitor and contactor work together in your air conditioner or heat pump to help power the fan and compressor. A telltale sign that one or both of these components has failed is when your air conditioning …

The contactor that controls the on and off of the capacitor is called the capacitor switching contactor, which is similar to the conventional contactor. However, there are some differences between them. The contactors for capacitor switching are composed of a conventional contactor as well as extra auxiliary contacts and wires (resistance wires).
The last step is to select the protection of the capacitors as well as the contactors. In order to do so, one has to skim the catalogue cards of the manufacturers. Contactors for the capacitor banks are specially designed, taking into account life expectancy of the contacts, as well as an extra module limiting the inrush current of the capacitor.

Capacitors are used in HVAC to help electrical motors to start and keep running smoothly. They are low-cost components that come in multiple packages, shapes, and sizes. What are Start Run Capacitors? A Start Capacitor holds a charge to start a motor moving. A Run Capacitor keeps a motor running smoothly with no big up and down spikes.

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.
