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

The ICP definite purpose contactor (OEM part 1178074) is a 2-pole, 30-amp electromagnetic switch with a 24-volt control coil used in the RGS150LDCB0AAAA gas furnace and matched condensing equipment. The contactor energizes when the 24V control signal reaches its coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common no-cool service calls: pitted, welded, or chattering contacts prevent the unit from starting or cause it to run intermittently. Replacing this inexpensive part restores reliable switching and protects the more expensive compressor and motor downstream.

Compatibility

This contactor is the factory-specified switching relay for the ICP/Tempstar/Heil RGS150LDCB0AAAA and is shared across many same-platform Carrier-family condensing units and furnaces that use a 24V control circuit with a 2-pole, 30A contactor. Always confirm your existing contactor is 2-pole, 30A, with a 24V coil before ordering.

Installation Guide

Safety First — Disconnect power at the breaker and the unit disconnect, then verify zero voltage with a multimeter before touching any wiring.
Access — Remove the electrical service panel to expose the contactor.
Document — Photograph every line, load, and coil wire before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor and reconnect each wire exactly as photographed (line to top terminals, load to bottom, 24V to the coil tabs).
Test — Restore power and confirm the contactor pulls in on a cooling call and that the compressor and fan energize cleanly with no chatter.

Buzzing, humming, or chattering from the contactor on a cooling call
Compressor and condenser fan fail to start even though the coil is energized
