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 genuine OEM 2-pole, 30-amp contactor (part number 1178074, CONTACTOR 2P 30A 24V) is the main switching relay for the ICP / Tempstar / Heil RHH048S0XA0AAAA 4-ton heat pump. Its 24V coil is energized by the thermostat through the control board; when it pulls in, the contactor closes its 30A line-voltage contacts to power the compressor and condenser fan motor. Contactors are a common failure point — pitted or welded contacts, a chattering or burned-out coil, and insect or debris fouling all prevent the outdoor unit from starting or cause it to stick on. Replacing a worn contactor restores clean, reliable switching and protects the compressor from voltage drop and arcing.
