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.

Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This OEM single-pole contactor (part number 1173690) is the line-voltage switch that energizes the compressor and condenser fan on the ICP / Heil / Tempstar WPG3602090RKB1 packaged unit. Rated 40 amps with a 24V coil, it pulls in when the thermostat calls for cooling and the control board sends 24V to the coil, closing the contacts to deliver line power to the compressor. Contactors are high-cycle wear parts: the contacts pit, burn, and weld over thousands of cycles, and the coil can fail open. Symptoms of a bad contactor include a unit that won't start, chattering or buzzing at the contactor, or a compressor that runs continuously because the contacts have welded shut.
