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 is the OEM definite-purpose contactor for the ICP / Heil / Tempstar RHS102H0AA0AAAA heat pump. The contactor is the electrically-operated switch that energizes the compressor and condenser fan motor whenever the 24-volt thermostat call closes its coil. Available in 2-pole 30-amp (PN 1178074) and 2-pole 40-amp (PN 1178211) ratings, both with a 24V control coil. When a contactor fails, the most common symptoms are a unit that hums but won't start, pitted or welded contacts that keep the compressor running, chattering from a weak coil, or no outdoor operation at all on a cooling or heating call.

Access — Remove the condensing unit's electrical access panel.
Document — Photograph every wire and terminal position before disconnecting anything.
Remove — Label and remove the line, load, and 24V coil leads, then unscrew the old contactor from its bracket.
Install — Mount the new contactor, transfer each wire to the matching terminal per your photo, and confirm the coil leads land on the 24V terminals.
Test — Restore power and place a thermostat call; verify the contactor pulls in cleanly and the compressor and fan energize.
