This OEM 2-pole definite purpose contactor (part #1059574) is the primary switching relay for the Tempstar TCA060AKA1 condensing unit. When the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. Rated at 40 amps per pole with a 24-volt coil, it is built to handle the high inrush current of compressor startups thousands of times over its service life. Common failure symptoms include a system that won't start, a chattering or buzzing noise at the contactor, pitted or welded contacts, or a unit that runs intermittently. Because the contactor carries full load current every cooling cycle, the contacts gradually erode and eventually fail to make clean connection.
