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 2-pole 30A contactor (part number 1171554) is the switching relay that energizes the high-voltage load on the ICP / Tempstar / Heil RGS303HREA0AAAA system. When the 24V coil is energized by the control circuit, the contactor closes its 30-amp poles to deliver line power. A larger 3-pole 60A contactor (1183142) is available for higher-load configurations. Contactor failure shows up as pitted or welded contacts, a chattering coil, or no power passing through when the system calls — leaving the unit unable to run. Pitting from arcing is a normal wear pattern that makes contactors a routine maintenance replacement.
