This OEM 2-pole, 30-amp contactor with a 24-volt coil (part 1178074) is the main switching relay for the compressor and condenser fan in the ICP / Tempstar / Heil RGS102SFBA0AAA packaged unit. When the thermostat calls for cooling, the 24V control signal energizes the contactor coil, pulling the contacts closed to deliver line voltage to the compressor and outdoor fan motor. Contactors are high-wear parts: the contacts pit and burn from arcing over thousands of cycles, the coil can open or weaken, and ants or debris can jam the plunger. Failure symptoms include a system that won't start, chattering or humming at the contactor, welded contacts that keep the compressor running, and burnt or pitted contact faces.
