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 contactor switches line voltage to the compressor and condenser fan in your ICP RGS150LRAA0AGAA package unit. When the thermostat calls for cooling, the 24V coil pulls in the contacts and energizes the load. Available in 30A (OEM 1178074) and 40A (OEM 1178211) ratings to match your exact unit, both with a 24V control coil. Contactors are a high-wear item — the contacts pit and burn over thousands of cycles, leading to chattering, dropped calls, or a unit that won't start at all.
