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.

Overview

This OEM 2-pole definite-purpose contactor is the switching relay for the ICP / Heil / Tempstar RGS091HSAB0AAAA system, available in 30-amp (part 1178074) and 40-amp (part 1178211) ratings with a 24-volt control coil. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed, sending line voltage to the compressor and condenser fan motor. Contactors are one of the most common failure points in HVAC equipment — the contacts pit, arc, and burn over thousands of cycles, eventually welding shut or failing to close. Symptoms include a system that won't start, chattering or humming at the contactor, or a unit that runs continuously and won't shut off.
