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 2-pole 30 amp contactor with a 24V coil (part #1178074) for the ICP / Tempstar / Heil RHH036H0CA0AAAA heat pump. The contactor is the high-voltage switch that powers the compressor and condenser fan motor. When the thermostat calls, the 24V coil pulls the contacts closed to send line voltage to the outdoor unit. Over time the contacts pit, weld, or burn and the coil can fail, causing the unit to chatter, fail to start, or refuse to shut off. A fresh 2-pole 30A OEM contactor restores clean, reliable switching and protects the compressor.
