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 is the electrically-operated switch that closes the high-voltage circuit to the compressor and condenser fan on your ICP RGS243HEFA0AAAA unit. When the 24-volt control coil energizes, the contactor pulls in and sends line voltage to the load; when the call ends it drops out and breaks the circuit. Available in the OEM ratings used on this platform — 2-pole 30A (1171554), 3-pole 40A (1172449), and 3-pole 60A (1183142) — all with a 24V coil. Contactors fail from pitted, burned, or welded contacts and from worn coils, leading to a unit that won't start, chatters, or won't shut off because the contacts have fused closed.
