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

Genuine OEM 2-pole definite-purpose contactors for the ICP / Tempstar / Heil RGS150HSCB0AAAA packaged unit, covering both the 30-amp (part 1178074) and 40-amp (part 1178211) ratings with a 24V control coil. The contactor is the electrically operated switch that closes line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil energizes, pulls the contacts closed, and passes 230V to the load. Pitted, burned, or chattering contacts are one of the most common reasons a unit won't start, hums, or trips on a hard start. These factory-spec contactors restore reliable, clean switching.
