Overview

This OEM definite-purpose contactor (part numbers 1178074 and 1178211) is the electromagnetic switch that controls high-voltage power to the compressor and condenser fan motor in your ICP RGS150LSAA0AGAA system. When the thermostat calls for cooling, the 24V control circuit energizes the coil, pulling the contacts closed to deliver line voltage to the load. The 1178074 is a 2-pole 30A unit; the 1178211 is a 2-pole 40A unit for higher-draw applications. Contactors are one of the most common HVAC failures — pitted, welded, or chattering contacts cause hard starts, buzzing, and units that won't shut off or won't start at all.
