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 2-pole definite-purpose contactor (part number 1178074) is the main switching relay for the ICP RHS072H0XA0AAAA heat pump condensing unit. Rated for 30 amps with a 24-volt control coil, it powers the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. A 24V signal from the control board energizes the coil, pulling the contacts closed to feed line voltage to the outdoor unit. Contactors are a leading cause of no-cool/no-heat outdoor units: contacts pit and burn over thousands of cycles until they weld closed or fail to make contact. Typical symptoms are a humming unit that won't start, chattering at the contactor, or a compressor and fan that stay dead despite a valid 24V call.

Compatibility

Engineered as the factory replacement for the ICP RHS072H0XA0AAAA heat pump.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the contactor line terminals.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph every wire and terminal location before disconnecting.
Remove — Note line, load, and 24V coil wiring, then transfer wires one at a time to the new contactor, or remove all wires and unscrew the old contactor from its bracket.
Install — Mount the new contactor, reconnect each wire to its matching terminal per your photos, and confirm the 24V coil leads are secure.
Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan energize.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?
