The contactor is the high-voltage relay that closes when your thermostat calls for cooling or heating, connecting line voltage directly to the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an AC unit that hums but won't start, a system that won't respond to a call from the thermostat, or visible pitting and burning on the contact surfaces. Replacing this part with the correct OEM unit restores reliable electrical switching and protects your compressor from premature failure caused by voltage irregularities.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole | 40A FLA (Full Load Amps) | 24V AC 50\/60Hz Coil | Direct OEM replacement for Carrier part number HN52TC040\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors are manufactured to Carrier's exact coil pull-in voltage and contact gap tolerances.
