OEM Payne Contactor 2-Pole 24V Coil for Model PA10JA030000AAAA
This is the OEM factory-specified contactor (part number HN51KB024) for the Payne PA10JA030000AAAA split-system air conditioner. The contactor acts as the primary high-voltage relay in your outdoor condensing unit, receiving a low-voltage signal (24V) from the thermostat and switching line voltage to energize the compressor and condenser fan motor. When the contactor fails, common symptoms include the outdoor unit refusing to start, audible chattering or buzzing at the contactor terminals, visible pitting or burning on the contact points, or the system running continuously without cycling off.
