ICP 1-Pole 30A Contactor for WCH5364GKA100 — 24V Coil | Ships Today

Overview

This OEM 1-pole 30-amp contactor (part #1172472) with a 24V coil and integrated shunt is the electrical relay that switches line power to the compressor and condenser fan on your ICP WCH5364GKA100. When the thermostat calls for cooling, the 24V coil pulls in the contactor's contacts, sending high-voltage power to the outdoor unit. Contactors are one of the most common failure points in any HVAC system because the contacts arc and pit every time they open and close. A failed contactor will leave the outdoor unit completely dead, cause chattering or buzzing, or — worse — weld shut so the compressor runs continuously. The built-in shunt provides the proper circuit path for this ICP application. Symptoms of a failing contactor include a humming outdoor unit that won't start, visibly burned or pitted contacts, and a clicking relay that won't hold in.
