Built to original equipment standards, it delivers reliable contact closure, low-resistance conduction, and safe load handling throughout its service life. It is an exact direct-fit replacement for Carrier model C50A403511, with matching coil voltage, pole configuration, and contact rating, so no rewiring or adapter brackets are required. Pitted, burned, or stuck contactor contacts are among the most common HVAC service issues, producing no-cool conditions, buzzing, or chattering — and this OEM part returns your system to factory-spec performance. Installation is a moderate, roughly 20 to 30 minute task: cut power at the disconnect, label and transfer each wire, then secure the new contactor. We recommend a licensed professional perform the work. Place your order before 3PM CST for same-day shipping and minimal cooling-season downtime.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model C50A403511.\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":62964415070579,"sku":"carrier-contactor-c50a403511","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-c50a403511","provider":"National HVAC Parts","version":"1.0","type":"link"}
