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 WTA3482000RKA1 condensing unit. The contactor is the heavy-duty electrical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V coil is energized it pulls the contacts closed, passing line voltage to the outdoor unit. With repeated arcing the silver contacts pit, burn, or weld, and the coil can eventually fail. Symptoms include an outdoor unit that will not start, a buzzing or chattering contactor, pitted or blackened contacts, and an AC that runs nonstop because the contacts have welded shut. A new contactor restores reliable, safe switching of the condenser.
