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 definite-purpose contactor is the electrically-controlled switch that energizes the compressor and condenser fan motor in your ICP RHS183S0AA0AAAA heat pump. When the thermostat calls for cooling or heating, the 24-volt control circuit pulls in the contactor coil, closing the line-voltage contacts and starting the outdoor unit. Available as a 2-pole 30-amp (OEM 1171554) or 3-pole 40-amp (OEM 1172449) device with a 24V coil, this is one of the most common failure points in any outdoor condensing unit. Pitted, burned, or chattering contacts cause hard starts, intermittent cooling, or a unit that hums but will not run. A coil that fails open leaves the system completely dead even though the thermostat is calling.

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.
