Overview

This is the genuine OEM 2-pole definite-purpose contactor (part 1178074, CONTACTOR 2P 30A 24V) for the ICP/Heil/Tempstar RGS101LFBA0AAAA system. The contactor is the electrical switch that closes the line-voltage circuit to the compressor and condenser fan when the 24V control coil is energized by the thermostat. Rated for 30 amps per pole with a 24-volt coil, it handles the high inrush of compressor startup. Failed contactors are one of the most common no-cool service calls — pitted or welded contacts, a buzzing chattering coil, or burnt terminals all point to replacement. Swapping the contactor restores reliable, clean switching.
