My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This OEM single-pole contactor is the high-voltage switch that energizes the compressor and condenser fan on your ICP system whenever the thermostat calls for cooling. Rated for 40 amps with a 24V control coil, it pulls in when the low-voltage circuit sends 24V to the coil and closes the line-voltage contacts. Contactors are one of the most common failure points in any condensing unit: the contacts pit and burn from repeated arcing, and the coil can stick or chatter. A failed contactor shows up as a unit that hums but won't start, contacts welded closed so the compressor never shuts off, or no response at all to a cooling call.
