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 number 1172472) for the ICP/Tempstar/Heil WCA3362GKR2 condensing unit. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24-volt control signal reaches the coil, the magnetic field pulls the contacts closed and sends line voltage to the outdoor unit. This unit is rated for 30 amps with a 24V coil and includes an integrated shunt. A failed contactor is one of the most common reasons an outdoor unit will not start — symptoms include a humming sound with no compressor start, pitted or welded contacts, a buzzing chatter, or an air conditioner that runs intermittently.

Compatibility

Engineered as a direct OEM replacement for the ICP/Tempstar/Heil WCA3362GKR2 air conditioning condenser. The same 1172472 contactor is used across many ICP-family split-system condensing units. Always confirm your existing contactor is a 1-pole, 30A, 24V coil unit before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condenser service panel to expose the electrical compartment.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note the L1/L2 line, load, and 24V coil leads, then transfer wires one at a time and unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo.
Test — Restore power, call for cooling, and confirm the contacts pull in and the compressor and fan start.
