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 40-amp contactor with a 24V coil (part number 1173690) for the ICP / Heil / Tempstar WPG4484130RKA1 packaged gas unit. The contactor is the high-voltage relay that switches line power to the compressor and condenser fan motor. When the thermostat calls for cooling, the control board sends 24V to the coil, the magnetic field pulls the contacts closed, and line voltage passes to the compressor circuit. A 40A rating provides the inrush headroom needed to start the compressor reliably. Over time the silver contacts pit, burn, or weld from arcing, and the coil can fail open. Failed contactors are one of the most common causes of a no-cooling call — the unit hums, chatters, or simply will not energize the compressor.
