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 genuine OEM 2-pole, 30-amp definite-purpose contactor (part number 1178074) with a 24-volt coil is the main switching relay for the ICP / Tempstar / Heil RGS102SRAA0AAA. When the thermostat calls and the 24V coil energizes, the contactor's two poles close to deliver line voltage to the compressor and condenser fan motor. Because it cycles tens of thousands of times per season under high current, the contacts eventually pit, burn, or weld — a leading cause of no-cool calls. A failed contactor can leave the outdoor unit dead, cause a constant hum, or stick closed so the compressor never shuts off. Replacing it with the correct OEM 2-pole 30A unit restores clean, reliable switching.
