Overview

This is the genuine OEM 2-pole, 30-amp contactor (part #1178074) for the ICP/Heil/Tempstar RHS036L0CA0AAA heat pump system. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. Its 24V control coil is pulled in by the low-voltage signal, closing two sets of line-voltage contacts to power the outdoor unit. Over years of cycling, the contacts pit, burn, and weld, and the coil can fail open — leaving you with an outdoor unit that hums, chatters, or won't start at all. Replacing a worn contactor is one of the most common and inexpensive HVAC repairs.
