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 is a genuine OEM 2-pole definite-purpose contactor (OEM part 1171554) for the ICP/Tempstar/Heil RGS243LTFA0AAAA gas furnace and matched condensing unit. Rated for 30 amps per pole with a 24-volt coil, the contactor is the electromechanical relay that switches line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V control signal energizes the coil, pulling the contacts closed to complete the high-voltage circuit. Over years of cycling, the silver-alloy contacts pit, burn, and weld, while the coil can open or short. A failing contactor causes hard starts, chattering, buzzing, or a unit that simply will not engage. Replacing it restores clean, reliable switching and protects the more expensive compressor downstream.
