This OEM 2-pole, 30-amp definite purpose contactor (part #1178074) with a 24V control coil is the main switching relay for the ICP / Heil / Tempstar RHS072S0BB0AAAA heat pump. When the thermostat calls for cooling or heating, the 24V coil pulls the contacts closed to deliver line voltage to the compressor and condenser fan motor. Contactors are high-wear parts — the contacts pit, burn, and weld over thousands of cycles, and ants or insects commonly lodge under the armature. A failing contactor causes the outdoor unit to hum without starting, chatter, or stay energized after the thermostat is satisfied. Installing a genuine 30A 24V OEM contactor restores clean, reliable switching and protects the compressor from low-voltage and chattering damage.
