What are the A/C Contact and Capacitor?
Your air conditioner’s contact and capacitor work together to help power your air conditioner’s fan and compressor whenever your thermostat calls for cool (the capacitor and contact in your heat pump work the same way).
The contactor is the “switch” that receives a low voltage (usually 24V) signal from your furnace to turn on. It’s a standard magnetic relay, meaning low voltage flows through a coil inside the contactor to creates a magnetic field, which then pulls down a piece of metal that connects both sides of the high-voltage circuit usually (120V or 240V).
Closing the circuit allows high voltage to power the fan and compressor motors. A contactor with one magnetic coil that connects one circuit is called a “single-pole,” if it has two magnetic coils that connect two circuits it’s called a “dual-pole,” and so on.
Air conditioning contactor replacement
The capacitor is like a “battery” that stores some of that high voltage goodness to create what’s called a “phase shifted current,” which is what causes your fan and compressor motors to spin.
Your A/C capacitor will be either a dual capacitor or a single capacitor. A dual capacitor has three sets of terminals on top: one for the compressor, one for the fan, and a shared “common” terminal for both to use. A single capacitor only has two terminals, and if your unit uses single capacitors, you probably have two of them in your system (one for the compressor and one for the fan).
