The contactor is the critical high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — your system will not respond to a call for cooling or heating. Common symptoms include the outdoor unit failing to start, buzzing or chattering at the contactor, or the system running continuously without cycling off.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole | 40A FLA (Full Load Amps) | 24V 50\/60Hz coil voltage | 240\/277V load voltage | OEM part number HN52TC040\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM contactor engineered to exact factory specifications.
