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, 30-amp contactor with a 24V coil (part number 1178074) is the primary switching relay for the ICP / Tempstar / Heil RGS120SFCA0AAA. When the control circuit sends 24 volts to the coil, the electromagnet pulls the double-pole contacts closed and delivers line voltage to the load — typically the compressor and condenser fan motor in a cooling or heat-pump section. Contactors are high-cycle, high-current devices and are one of the most common HVAC failures: the contact points pit, arc, and burn over time, and the coil can open or weaken. Symptoms of a failing contactor include a system that will not start, a humming or chattering contactor that won't pull in, contacts that weld closed so the unit runs continuously, and visible burning or pitting on the contact faces. This direct-replacement contactor restores clean, reliable switching.
