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.

Overview

This genuine OEM 2-pole, 30-amp contactor (part number 1178074) is the switching relay for the ICP / Tempstar / Heil RGS102LFBB0AAA. Energized by a 24-volt control signal, its electromagnetic coil pulls the two main power contacts closed to deliver line voltage to the system. Contactors are a top wear item: the contact points arc every time they open and close, and over thousands of cycles they pit, burn, and weld. A failing contactor shows up as a unit that won't start, chatters or buzzes, or one that won't shut off because the contacts have fused together. This OEM-spec 30A 2-pole contactor with a 24V coil restores reliable switching.
