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 2-pole definite-purpose contactor (OEM part number 1178074) rated at 30 amps with a 24-volt coil, built for ICP/Tempstar/Heil equipment including model RGS091LTBA0AAAA. A contactor is the electrically operated switch that energizes the high-voltage load when the 24V control circuit calls for operation. When the coil receives 24V from the control board or thermostat circuit, the electromagnet pulls the contacts closed and power flows to the connected load. Worn, pitted, or welded contacts are one of the most common HVAC failures — they cause hard starting, chattering, intermittent operation, or a unit that will not start at all. Replacing a failing contactor with the correct OEM 2-pole 30A 24V part restores reliable switching and protects downstream components from voltage drop and arcing.

Compatibility

This OEM contactor is designed for ICP-family equipment (Tempstar, Heil, Comfortmaker, Arcoaire) and is a direct fit for model RGS091LTBA0AAAA. Always confirm the existing part carries number 1178074 or a listed superseding number, and verify the coil is 24V and the contacts are rated 30A before installing.

Installation Guide

Safety First — Disconnect power at the breaker and the unit disconnect. Verify zero voltage at the contactor terminals with a multimeter before touching any wiring.
Access — Remove the service / electrical access panel to expose the contactor.
Document — Photograph every wire and terminal position before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor from its bracket.
Install — Mount the new 1178074 contactor, reconnect each wire to the matching terminal per your photo, and confirm the coil leads land on the 24V terminals.
Test — Restore power, call for operation, and confirm the contactor pulls in cleanly with no chatter and full voltage across the load.

Is this contactor compatible with Bryant or Payne too?
