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 single-pole definite purpose contactor (part #1173690) for the ICP/Tempstar/Heil WPG3484115LKC1 packaged unit. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the 24V thermostat signal calls for cooling. When the coil receives 24 volts, the magnetic plunger pulls the main contacts closed, passing line voltage to the compressor circuit. Rated for 40 amps with a 24V control coil, it handles the high inrush current of compressor startup. A failing contactor is one of the most common causes of an outdoor unit that hums but won't start, or a system that won't shut off — pitted, burned, or welded contacts and a chattering or dead coil are the usual culprits.
