The contactor is a high-voltage relay that bridges the gap between your thermostat's 24V control signal and the high-voltage power feeding the compressor and condenser fan motor. When it fails, the most common symptom is an air conditioner that simply won't turn on — the thermostat calls for cooling, but nothing happens at the outdoor unit. You may also notice pitting or burning on the contactor contacts from years of electrical arcing, or hear a loud chattering\/buzzing from the contactor coil.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 2-Pole configuration | 24V AC coil voltage | 30–40 amp contact rating | Direct OEM replacement for part number HN51KC024 | Factory-matched contact material for full rated service life\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors use silver-alloy contacts rated to the exact amperage draw of your Carrier system.
