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 single-pole definite purpose contactor (part number 1172472) is the genuine 30-amp, 24-volt coil contactor with shunt for the ICP / Tempstar / Heil WCH3362GKR4 heat pump. The contactor is the electrically operated switch that sends line voltage to the compressor and condenser fan whenever the 24V control circuit calls for cooling or heating. The integrated shunt provides the second leg connection in a single-pole design. Over time the silver contacts pit, burn, and weld from arcing, while the coil can fail open — both leave the outdoor unit dead even though the thermostat is calling. A fresh contactor restores clean, reliable switching and protects the compressor from chatter and low-voltage drop.

Installation Guide

Safety First — Disconnect power at the condenser disconnect and verify zero voltage with a multimeter on both line terminals.
Access — Remove the condenser service panel to expose the electrical compartment.
Document — Photograph every line, load, and 24V coil wire before disconnecting.
Remove — Pull the leads, unscrew the contactor from its mounting bracket, and lift it out.
Install — Mount the new contactor and reconnect each lead to the matching terminal per your photo.
Test — Restore power and confirm the contactor pulls in cleanly on a call and that the compressor and fan energize.
