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 number 1050699) for the ICP / Tempstar / Heil YJ018GA3 heat pump. The contactor is a 24V-coil-activated switch rated for 25 amps that energizes the compressor and outdoor fan motor whenever the thermostat calls for cooling or heating. When the 24V control signal reaches the coil, the magnetic field pulls the contacts closed and sends line voltage to the condensing unit. Common failure symptoms include a buzzing or chattering outdoor unit, pitted or welded contacts that prevent the unit from shutting off, and a compressor that will not start because the contacts no longer close. A worn contactor is one of the most frequent causes of a no-cooling service call.
