This is the factory OEM replacement contactor (part number HN51KC024) for the Payne PA17NA02400GBBAA split-system air conditioner. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When a contactor fails — due to worn or pitted contacts, a burned coil, or contacts welded shut — the result is an AC unit that won't turn on, runs continuously without shutting off, or trips the breaker repeatedly. Replacing the contactor is one of the most common and cost-effective AC repairs available.
Compatibility: Designed specifically for the Payne PA17NA02400GBBAA 2-ton split-system air conditioner. Cross-reference OEM part number HN51KC024 against your unit's data plate and existing contactor label before ordering. Not sure if this is the right part?
