The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to allow 240V power to flow to the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an AC unit that runs continuously and won't shut off (contacts welded closed), or a unit that receives a call for cooling but never starts (contacts burned open or coil failure).\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-pole configuration | 24V AC coil voltage | Rated for 30A compressor load | Direct OEM replacement for Carrier part HN51KC024 | Factory-matched contact material for long service life\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM HN51KC024 contactor uses factory-specified silver-alloy contacts rated to exact amperage loads for the CA13NA04800GAAAA.
