OEM Carrier 2-Pole Contactor HN53CB115 for Model C4850C50AW02011

This is the factory OEM replacement contactor (part number HN53CB115) for the Carrier C4850C50AW02011 packaged unit. The contactor is a high-voltage relay controlled by the 24V signal from your thermostat and control board. When you call for cooling, the contactor closes its contacts to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an AC unit won't turn on — symptoms include the outdoor unit staying completely off, chattering or buzzing from the contactor coil, or visible pitting and burning on the contact points.
