This OEM 2-pole, 30-amp contactor with a 24V coil (part 1178074) is the primary switching relay for the ICP/Tempstar/Heil RGS091LEAB0AAAA. When the thermostat calls for cooling, the 24-volt control signal energizes the coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. Contactors are a high-wear part: the contacts arc every time they open and close, eventually pitting, welding shut, or chattering. A failed contactor is a frequent cause of an outdoor unit that won't start, won't shut off, or buzzes loudly. This OEM-spec replacement restores reliable 30A switching.
