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 energizes the compressor and condenser fan motor in your ICP RHS183L0CA0AAAA heat pump. On a thermostat call, the 24-volt coil pulls the contacts closed, sending line voltage to the outdoor unit. Offered as a 2-pole 30-amp (OEM 1171554) or 3-pole 40-amp (OEM 1172449) device with a 24V coil, the contactor is among the highest-wear electrical parts in any condensing unit. Pitted or welded contacts cause hard starts, chattering, and intermittent cooling, while an open coil leaves the unit dead despite a calling thermostat. A fresh contactor restores reliable starting and protects the compressor from damaging voltage drops.

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.
