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 RGS300LREA0AAAA. The contactor is the heavy-duty relay that switches line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil is energized by the control circuit, pulling the contacts closed to deliver power to the high-voltage components. When a contactor fails, the contacts pit, weld, or chatter — leaving you with a unit that won't start, hums without engaging, or short-cycles. Replacing it with the correct 2-pole 30A OEM part restores reliable switching and protects your motor and compressor from low-voltage damage.
