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 definite-purpose contactor switches line voltage to the compressor and condenser fan in the ICP RGS243HREA0AAAA. The 24V coil pulls in the contacts whenever the thermostat calls for cooling, sending power to the outdoor unit. This listing covers the 2-pole 30A contactor (OEM 1171554); the RGS243 platform also uses the 3-pole 40A (1172449) and 3-pole 60A (1183142) variants depending on configuration. Contactors fail from arcing, pitted or welded contacts, and worn coils — symptoms include a chattering buzz, an outdoor unit that won't energize, or a unit that won't shut off because the contacts are stuck closed. A fresh OEM contactor restores clean, reliable switching and protects downstream components.
