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 contactor (part number 1173690) is the 1-pole, 40-amp, 24V-coil contactor that switches line power to the compressor and condenser fan in the ICP / Tempstar / Heil WPG4604090RKB1 packaged unit. When the thermostat calls for cooling, 24V from the control transformer energizes the coil, pulling the contacts closed to send high voltage to the outdoor components. Because the contacts make and break under load thousands of times, they eventually pit, burn, or weld. Symptoms of a failing contactor include a buzzing or chattering coil, the outdoor unit that won't start on a cool call, contacts that stay stuck closed so the unit runs nonstop, or visibly burned/melted terminals. Replacing a worn contactor restores clean, reliable switching and protects the compressor.
