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 is a genuine ICP 2-pole 30-amp contactor with a 24V coil (OEM part 1178074) for the RHS150S0CA0AAAA condensing unit. The contactor is the high-voltage switch that powers the compressor and condenser fan whenever the thermostat calls. A 24V signal energizes the coil, pulling the contacts closed to pass line voltage to the load. Contactors wear out from arcing, pitting, and stuck or chattering contacts — the result is a unit that won't start, hums but won't engage, or runs when it shouldn't. Pitted or welded contacts are a leading cause of no-cool service calls. This OEM contactor restores clean, reliable switching.
