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 definite purpose contactor (part #1173690) is a single-pole, 40-amp unit with a 24-volt coil built for the ICP WJH348000KTP0A1 heat pump. The contactor is the heavy-duty relay that switches line voltage to the compressor and condenser fan when the thermostat calls for cooling. The 24V coil pulls the contacts closed; pitted, burned, or chattering contacts are one of the most common reasons an outdoor unit stops responding. Symptoms of a failing contactor include a unit that hums but does not energize, contacts welded shut so the system runs continuously, a buzzing or chattering sound at the contactor, and visible arcing or melted terminals. Replacing a worn contactor is inexpensive insurance against burned wiring and compressor damage.
