Overview

This OEM 2-pole definite-purpose contactor is the electrically operated switch that energizes the compressor and condenser fan circuits in your ICP RGS150HRAA0AGAA system. A 24-volt signal from the thermostat or control board pulls in the contactor coil, closing the line-voltage contacts that feed the load. This listing covers the genuine factory replacements 1178074 (2-pole, 30A, 24V coil) and 1178211 (2-pole, 40A, 24V coil). Failed contactors are one of the most common no-cool service calls — pitted, welded, or chattering contacts prevent the unit from starting or cause it to run intermittently.
