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.

Overview

This is a genuine OEM single-pole definite purpose contactor (part #1172472) for the ICP / Tempstar / Heil WJA336000KTP0A1 system. The contactor is the heavy-duty switch that delivers line voltage to the outdoor compressor and condenser fan motor. On a cooling call, the 24-volt control circuit energizes the contactor coil, pulling the 30-amp contacts closed; the built-in shunt keeps a continuous path on the unswitched leg. Pitted contacts, a buzzing or stuck coil, and heat-damaged terminals are the usual culprits behind a no-cool condition and should be addressed promptly to protect the compressor.

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 — Transfer the line/load and coil leads one terminal at a time, then unbolt the old contactor from its 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.
