Overview

This OEM single-pole contactor (part number 1173690) is rated 40 amps with a 24-volt control coil and is the factory-specified switching relay for the ICP WTA3602000RKA1 condensing unit. The contactor is the heavy-duty electrical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil pulls the contacts closed, passing line voltage to the outdoor unit. Over time the silver contacts pit, burn, or weld from arcing, and the coil can fail open. Symptoms include an outdoor unit that will not start, a chattering or buzzing contactor, pitted or blackened contacts, and a system that runs continuously because the contacts have welded shut. Replacing a worn contactor restores reliable, safe switching.
