The contactor is the high-voltage relay that opens and closes the compressor and condenser fan circuit every time your thermostat calls for cooling or heating. When contacts become pitted, burned, or welded shut — or when the 24V coil fails to pull in — the unit will either refuse to start or run continuously with no thermostat control. This is one of the most common service calls in residential HVAC.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole | 30A FLA \/ 150A LRA | 24 VAC Coil | 50\/60 Hz | OEM Part# HN51KC024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, engineered to exact factory specifications for the PH4ANG042000BBAA.
