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 a genuine OEM 2-pole definite purpose contactor (part number 1178074) for the ICP/Tempstar/Heil RHH036S0BA0AAAA heat pump. The contactor is the electrically controlled switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. It carries a 30 amp per pole load rating and is actuated by a 24-volt control coil. When the coil pulls in, the silver-cadmium contacts close and pass line voltage to the outdoor unit; when the call ends, the spring-loaded armature drops out and isolates the load. Common failure symptoms include a unit that hums but will not start, a buzzing or chattering outdoor unit, pitted or welded contacts that keep the compressor running continuously, and visible arcing or burn marks on the contact terminals.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the line terminals.
Access — Remove the outdoor unit's electrical service panel.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Label and pull the wires off the old contactor, then unscrew it from the mounting bracket.
Install — Mount the new contactor, transfer each wire to the matching terminal per your photo, and confirm the 24V coil leads land on the coil tabs.
Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement
