The contactor is the high-voltage relay that bridges your 24V thermostat signal to the 240V power supply feeding the compressor and condenser fan. When it fails, the most common symptom is an AC system that simply won't turn on — the thermostat calls for cooling, but nothing happens. In some cases a stuck-closed contactor causes the outdoor unit to run continuously even when the thermostat is satisfied.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole configuration | 24V AC coil voltage | Factory-matched contact rating for Carrier PY3PNA030060AA | OEM part number HN51KB024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM contactor meets exact Carrier factory specifications for contact gap, coil pull-in voltage, and amp rating.
