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 the genuine ICP 2-pole, 40-amp definite-purpose contactor (part 1178211) with a 24-volt coil, used on the RGS091HTCB0AAA. A contactor is the electrically operated switch that closes the high-voltage circuit to the compressor and condenser fan motor whenever the 24V control circuit energizes the coil. When the thermostat calls for cooling, the low-voltage coil pulls the contacts closed, sending line power to the load. Over time the silver contacts pit, burn, and weld from the constant arcing of inrush current, while the coil can hum, chatter, or fail open. A failing contactor causes hard starts, buzzing, intermittent operation, or a system that will not run at all. This 40A 24V unit is a direct OEM replacement rated for reliable, repeatable switching.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
