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, 40-amp definite purpose contactor (OEM part number 1176763) is built for the ICP/Tempstar/Heil WCA3602AKN300 air conditioning condensing unit. A contactor is the high-current relay that switches line voltage to the compressor and condenser fan motor each time the thermostat calls for cooling. The 24-volt control coil magnetically pulls the contacts together to complete that circuit. Repeated arcing slowly erodes the silver contact surfaces, producing resistance, heat, and voltage drop that can stress or stall the compressor. A fresh contactor restores reliable switching and prevents the nuisance no-cool calls that come from a tired, pitted part.
