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 single-pole definite purpose contactor (part #1172472) for the ICP / Tempstar / Heil WJA336000KTP0A2 system. The contactor is the electromechanical switch that energizes the outdoor condensing unit. When the thermostat calls for cooling, the 24-volt control circuit pulls in the contactor coil, closing the 30-amp line-voltage contacts that power the compressor and condenser fan motor. The integrated shunt provides a continuous current path on the unswitched leg. A failing contactor is one of the most common no-cool service calls — pitted or welded contacts, a chattering or buzzing coil, and burnt terminals all point to replacement.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor line terminals with a multimeter.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Note terminal positions, transfer the line/load and coil leads one at a time, then unbolt the old contactor from its mounting bracket.
Install — Mount the new contactor and reconnect every wire exactly per your photo, confirming the shunt leg is on the correct side.
Test — Restore power, call for cooling, and verify the contactor pulls in cleanly with no chatter and the compressor energizes.

Signs You Need a Replacement
