This OEM 2-pole contactor (part #1059574) is the line-voltage switch that powers the compressor and condenser fan in your Tempstar TCA060AKC1 condensing unit. When the thermostat calls for cooling, a 24V control signal energizes the coil and closes both poles, sending full voltage to the outdoor equipment. Rated for 40 amps with a 24V coil, the double-pole design breaks both supply legs for safer, more complete switching. Contactors wear out — every switching cycle arcs the contacts, which over time pit, burn, or weld shut, producing the classic no-cool symptom. A humming or chattering contactor indicates a failing coil. Swapping in the correct OEM contactor restores clean, reliable switching and protects the compressor from arcing damage and voltage spikes.
