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 genuine OEM 2-pole, 30-amp contactor with a 24-volt coil (part 1178074) is the switching relay that energizes the compressor and condenser fan on the ICP Tempstar Heil RGS101SRAB0AAAA. When the thermostat calls for cooling, 24V power energizes the coil, pulling the contacts closed to deliver line voltage to the outdoor unit. Pitted, burned, or chattering contacts are one of the most common causes of a no-cool condition, hard starting, or a unit that buzzes but won't run. Replacing a worn contactor with the correct OEM part restores reliable switching and protects the compressor.
