The contactor energizes the compressor and outdoor fan motor each time your thermostat calls for cooling, using a low-voltage coil to close high-voltage contacts that carry the load safely. Worn or pitted contacts cause hard starts, chattering, or a unit that won't run — replacing the contactor restores reliable operation. Built to exact factory specifications, the C50A303511 drops directly into Carrier model C50A303511 with no modification, preserving correct coil voltage, pole configuration, and amperage rating. Installation is straightforward for a qualified technician: disconnect power, photograph and transfer the wiring, swap the contactor, and restore power — typically a 20-30 minute job. Always confirm the coil voltage matches your existing part before installing. Backed by genuine OEM quality for long service life and proper fit. In stock and ready to ship same-day when you order before 3PM CST, so your system is back up and cooling fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model C50A303511.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62964830044531,"sku":"carrier-contactor-c50a303511","price":42.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-c50a303511","provider":"National HVAC Parts","version":"1.0","type":"link"}
