This OEM 2-pole contactor (part #1059574) is the line-voltage switch that energizes the compressor and condenser fan in your Tempstar TCA060AKC3 condensing unit. On a cooling call, the 24V control circuit pulls in the coil and closes both poles, delivering full power to the outdoor equipment. Rated at 40 amps with a 24V coil, the double-pole layout breaks both supply legs for safer and more complete switching. Because the contacts arc on every cycle, contactors gradually pit, burn, and eventually weld or fail open — the leading cause of a no-cool outdoor unit. A buzzing or chattering contactor signals a worn coil. Replacing it with the correct OEM part restores dependable switching and shields the compressor from arcing and voltage spikes.
