This is the factory OEM replacement contactor (part number HN51JD026) for the Payne PA16NA06100GBAAA split-system air conditioner. The contactor is a high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to send 240V power to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a stuck plunger, or a burned coil — your outdoor unit will not energize at all, or may run continuously without shutting off, even when cooling demand is satisfied.
Compatibility: Engineered as an exact drop-in replacement for the Payne PA16NA06100GBAAA 5-ton, 16 SEER single-stage split-system condenser. Confirm your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our fitment team is available to verify compatibility prior to purchase — in stock and ready to ship today.
