Overview

This genuine OEM 2-pole definite purpose contactor (part number 1171554) is the switching component for the ICP/Tempstar/Heil RGS303LRAA0AAAA system. Rated at 30 amps with a 24-volt coil, the contactor closes its contacts when the thermostat calls for cooling, passing line voltage to the compressor and condenser fan motor. Constant make-and-break cycling pits and erodes the contact points over time, and a worn contactor is a leading cause of a unit that hums without starting, chatters, or refuses to shut off when the contacts weld closed. Installing a fresh OEM contactor restores clean switching and protects the costlier motor and compressor on the load side.
