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 (OEM part #1172472) for the ICP/Heil/Tempstar WCH3302GKA1 heat pump condensing unit. The contactor is the electrically operated switch that powers the compressor and outdoor fan motor whenever the thermostat calls for cooling or heating. It is rated for 30 amps with a 24-volt coil and includes an integrated shunt. When the 24V coil energizes, the contacts close and pass line voltage to the compressor; when the call ends, a spring opens the contacts. Pitted, welded, or chattering contacts are one of the most common causes of a heat pump that won't start, hums, or runs intermittently.
