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 is available in 30 amp (part 1178074) and 40 amp (part 1178211) ratings, both with a 24-volt coil, for the ICP / Tempstar / Heil RGS091HRBB0AAAA system. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the 24V control circuit calls. Each time it pulls in, the contacts arc slightly, so over thousands of cycles they pit, burn, and weld — or the 24V coil opens. Common failure symptoms include the outdoor unit not starting, a humming or chattering contactor, contacts stuck closed so the unit won't shut off, or visibly burnt and pitted contacts. Choose the 30A or 40A version to match your original; both share the standard 2-pole, 24V-coil configuration.
