Overview

This OEM 2-pole definite purpose contactor fits the ICP Tempstar/Heil RHS150H0EA0AAAA heat pump and is offered in both 30 amp (part 1178074) and 40 amp (part 1178211) ratings, each with a 24-volt control coil. The contactor is the high-current switch that energizes the compressor and condenser fan motor whenever the thermostat calls. Its contacts carry full line voltage and take a beating every cycle, so they pit, weld, or burn over time. A failing contactor causes hard starts, chatter, a humming buzz, or a unit that won't run at all. This genuine ICP replacement restores clean, reliable switching.
