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) with a 24-volt coil switches line-voltage power to the compressor and condenser fan in ICP Tempstar Heil RGS-series systems. When the thermostat calls and the 24V coil energizes, the electromagnet pulls the contacts closed, sending power to the load; when the call ends, a spring opens the contacts. Because the contacts carry high current and cycle constantly, they eventually pit, burn, or weld, and the coil can fail open. A bad contactor is one of the most common no-cool service calls. Typical symptoms include a system that won't start, contacts that chatter or buzz, visible arcing or pitting on the contact faces, or a compressor that runs even after the thermostat is satisfied.
