This OEM 2-pole contactor (part number 1178074) is the primary switching relay for the ICP RHH102S0AA0AAAA heat pump. Rated at 30 amps with a 24-volt control coil, the contactor energizes the compressor and outdoor fan motor whenever the thermostat calls for cooling or heating. When the 24V coil is energized, the magnetic field pulls the contacts closed and delivers line voltage to the condensing unit. Over time the silver contacts pit, burn, and weld from the constant arcing of high-amperage switching, while the coil can open or short. A failing contactor is one of the most common causes of an outdoor unit that hums but will not start, chatters, or runs intermittently. Replacing it with this exact OEM-spec 30A 2-pole, 24V part restores reliable, safe operation.
