OEM Carrier Contactor 24V 2-Pole for Model PY3PNA036060NA (HN51KB024)

This is the factory OEM replacement contactor for the Carrier PY3PNA036060NA condensing unit. The contactor is a high-voltage relay controlled by the thermostat's 24V signal — when the thermostat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons a condensing unit won't turn on at all, hums without starting, or runs continuously without shutting off.
