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 single-pole contactor (part #1173690) is the electrical switch that powers the compressor and condenser fan motor in your ICP WPA4604000RKB1 condensing unit. Rated for 40 amps with a 24-volt control coil, it energizes when the thermostat calls for cooling, closing the contacts to send line voltage to the outdoor unit. Over time the contact points pit, burn, and weld from repeated arcing, leading to a unit that won't start, chatters, or refuses to shut off. A failed contactor is one of the most common no-cool service calls, and replacing this 40A 24V part restores reliable 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.
