The contactor receives a low-voltage signal (120V coil) from the control board and closes its 2-pole contacts to energize the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a welded\/stuck plunger, or a failed coil — the system will either refuse to turn on entirely, experience intermittent compressor dropout, or run continuously without shutting off.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole | 120V Coil | 30 Amp FLA | 50\/60 Hz | Definite Purpose Contactor | Factory part number HN52KC052\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part.
