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 OEM 2-pole definite-purpose contactor (part number 1171554) rated for 30 amps with a 24-volt coil, built for the ICP / Heil / Tempstar RGS300LRAA0AAAA. The contactor is the heavy-duty relay that switches line voltage to the compressor and condenser fan motor on a call for cooling. The 24V coil is energized by the control circuit, pulling the contacts closed to send power to the high-voltage loads. When a contactor wears out, the contacts pit, weld, or chatter — causing a unit that won't start, hums without engaging, or short-cycles. Installing the correct 2-pole 30A OEM contactor restores reliable switching and protects the motor and compressor.
