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 for the ICP (International Comfort Products) RGS101HFAA0AAAA system is a 2-pole unit with a 24-volt coil, available in both 30 amp (part 1178074) and 40 amp (part 1178211) ratings. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor when the thermostat calls for cooling. The 24V coil pulls the contacts closed to pass line voltage to the load. Contactors are among the most common failure points in HVAC systems: contacts pit and burn from arcing, and coils weaken or stick, causing no-cool calls, chattering, or a system that won't shut off. A fresh OEM contactor restores reliable switching.
