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

The ICP 1178074 is an OEM 2-pole, 30-amp definite-purpose contactor with a 24-volt coil, used on the RGS091LDCA0AAA platform to switch line-voltage power to the condensing unit's compressor and fan motor. When the thermostat calls for cooling, the 24V control circuit energizes the coil, pulling the contacts closed to deliver power to the outdoor load. Contactors are a high-wear part: the contacts arc on every cycle and eventually pit, burn, or weld, while the coil can open or buzz with age. A failing contactor shows up as a unit that won't start, chatters, or stays running after the call ends because the contacts have welded shut. Replacing it with the correct 30A / 24V OEM-spec part restores clean, reliable switching.
