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 is a genuine OEM 2-pole definite purpose contactor (part number 1171554) for the ICP/Tempstar/Heil RGS303LREA0AAAA system. The contactor is a 30-amp, 24-volt coil electromagnetic switch that energizes the high-voltage circuit feeding the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V control signal reaches the coil, the magnetic field pulls the contacts closed and line voltage passes to the load. Over time the contact points pit, arc, and weld from the constant make-and-break cycling, which is the single most common cause of a unit that hums but won't start, chatters, or fails to shut off. Replacing a worn contactor restores clean, reliable switching and protects the more expensive motor and compressor downstream.
