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 single-pole 30 amp definite-purpose contactor (part #1172472) with a 24V coil and integrated shunt for the ICP/Tempstar/Heil WJH442000KTP0A1 heat pump. The contactor is the high-voltage relay that the 24V thermostat circuit uses to switch line power to the compressor and condenser fan motor. On a call for cooling or heating the 24V coil pulls the contacts closed; when the contacts pit, weld, or the coil opens, the outdoor unit either won't start, chatters, or runs continuously. The built-in shunt protects against transient surges on the load side.
