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 OEM definite-purpose contactor is the electromechanical switch that energizes the high-voltage circuit in your ICP/Tempstar/Heil RGS300HRAA0AAAA gas furnace and its companion condensing unit. When the 24V control signal from the thermostat hits the coil, the contactor pulls in and closes the line-voltage contacts that feed the compressor and/or blower. This listing covers two OEM options: part 1171554 (2-pole, 30A, 24V coil) and part 1183142 (3-pole, 60A, 24V coil). A failing contactor is one of the most common no-cool / no-heat call-outs — pitted or welded contacts cause chatter, intermittent operation, or a unit that simply won't start.

Installation Guide

Access — Remove the control-panel service panel to expose the contactor.
Document — Photograph every wire and terminal position before disconnecting anything.
Remove — Label and disconnect line, load, and 24V coil leads, then unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor, transfer the wires terminal-for-terminal per your photo, and confirm tight connections.
Test — Restore power and call for cooling/heating; confirm the contactor pulls in cleanly with no chatter.
