This OEM 2-pole, 40-amp definite purpose contactor (part number 1172786) is the electromechanical switch that delivers line voltage to the compressor and condenser fan in your Tempstar T4A360GKD200 condensing unit. A 24-volt signal from the thermostat energizes the coil, closing both poles to start the cooling cycle. Over time the contacts pit, burn, or weld, and the coil can weaken — producing symptoms like a buzzing or chattering contactor, a unit that won't start, or a compressor that runs continuously. This factory-spec replacement restores clean, reliable switching and protects the compressor circuit.
