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

These are the genuine OEM contactors for the ICP / Tempstar / Heil RGS243HDEA0AAAA system, available in 2-pole 30A (1171554), 3-pole 40A (1172449), and 3-pole 60A (1183142) configurations — all with a 24V control coil. The contactor is the electromagnetic switch that closes the high-voltage circuit to the compressor and condenser fan when the 24V coil is energized by the thermostat. Burned, pitted, or chattering contacts are one of the most common HVAC service failures, causing no-cool calls and hard starts. Installing the correct OEM contactor restores clean, reliable switching.

Is this contactor compatible with Bryant or Payne too?
