The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and\/or fan motor. When the contactor fails — through burned or pitted contacts, a welded coil, or an open coil — your system will either refuse to turn on entirely, run continuously without cycling off, or hum without the compressor starting. Replacing a worn contactor promptly prevents costly compressor damage from voltage irregularities.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole configuration | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 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 tolerances for the PH10JA04800GABAA.
