This is the factory OEM replacement contactor (part HN51JD026) for the Carrier CH13NA06100GBABA split-system air conditioner. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from your thermostat and switches line voltage to the compressor and condenser fan motor. When the contactor fails — through pitted contacts, a burned coil, or a stuck plunger — your system may hum without starting, fail to respond to a cooling call, or trip the breaker repeatedly. Replacing it with an OEM-matched unit restores safe, reliable operation.
Compatibility: Designed as a direct OEM replacement for the Carrier CH13NA06100GBABA condenser unit. Verify coil voltage and pole configuration on your existing contactor's label before ordering.
