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 contactor is the primary switching relay for the ICP/Heil/Tempstar RGS300HSFA0AAAA system. The contactor energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the low-voltage 24V control signal reaches the coil, the contactor pulls in and closes its high-voltage power contacts, sending line voltage to the compressor. Two configurations are available for this model: part 1171554 (2-pole, 30A, 24V) and part 1183142 (3-pole, 60A, 24V). Failure symptoms include a buzzing or chattering sound, pitted or welded contacts that prevent the unit from shutting off, and an outdoor unit that fails to start even though the thermostat is calling for cooling.

Installation Guide

Safety First — Disconnect power at the breaker and pull the outdoor disconnect. Verify zero voltage with a multimeter across all terminals.
Access — Remove the condenser or furnace service panel to expose the control area.
Document — Photograph all wire connections on the existing contactor before disconnecting anything.
Remove — Note line, load, and 24V coil terminal positions, then transfer wires one at a time to the new contactor to avoid mis-wiring. Unscrew the old contactor from its bracket.
Install — Mount the new contactor, reconnect each wire exactly per your photo, and confirm the coil terminals receive the 24V leads.
Test — Restore power and trigger a cooling call. Confirm the contactor pulls in cleanly with no chatter and the compressor energizes.
