OEM Carrier 1-Pole Contactor 30 Amp 24V Coil for Model PH10JA036000AGAA (HN51KC024)

This OEM Carrier contactor (part# HN51KC024) is the factory-specified replacement for the Carrier PH10JA036000AGAA heat pump unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to deliver line voltage to the compressor and condenser fan motor. When the contactor fails, the system may refuse to start, run continuously without shutting off, produce audible chattering or humming from the electrical panel, or show visible pitting and burning on the contact surfaces. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs available.
