Overview

This is a genuine OEM 2-pole definite purpose contactor (Part Number 1178074) for the ICP / Tempstar / Heil RGS101LTBA0AAAA. Rated for 30 amps with a 24-volt control coil, the contactor is the electromechanical switch that energizes the compressor and condenser fan motor when the thermostat calls for cooling. When the 24V coil is energized, the contacts close and pass line voltage to the high-current loads. Pitted, burned, or chattering contacts are one of the most common causes of a system that won't start, hums but won't run, or short-cycles. Replacing a failing contactor restores reliable starting and protects downstream components from voltage drop and arcing damage.
