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 OEM 2-pole definite purpose contactor switches line voltage to the compressor and condenser fan in the ICP/Heil/Tempstar RHS150H0CB0AAAA heat pump. Available as the 30-amp (OEM 1178074) and 40-amp (OEM 1178211) variant, both energized by a 24-volt coil. When the thermostat calls for cooling or heating, the 24V coil pulls the contacts closed to power the outdoor unit. A failed contactor is one of the most common no-cooling causes: pitted or welded contacts keep the compressor running, while a burned-out coil prevents the unit from starting at all. Replacing it restores reliable, safe switching of the high-current outdoor loads.
