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 the genuine OEM 2-pole definite-purpose contactor for the ICP / Heil / Tempstar RGS091HRAB0AAAA system, available as the 30-amp version (part #1178074) and the 40-amp version (part #1178211), both with a 24-volt coil. The contactor is the electrically operated switch that energizes the unit when the thermostat calls; its coil pulls the contacts closed to pass line voltage to the load. Over time the contacts pit, burn, or weld from arcing, and the coil can fail open. Symptoms include the unit not starting, chattering or buzzing, or contacts that stay stuck closed so the unit will not shut off. Installing a fresh OEM contactor restores reliable switching.
