When your thermostat calls for cooling, the 24V control coil pulls the contacts closed, energizing the condensing unit; when the call ends, the contacts open and shut the unit down. Pitted, welded, or chattering contacts are a leading cause of a system that won't start, hums, or trips breakers. Built to exact factory specifications for Carrier model C48A502511, this is a direct OEM replacement that restores reliable, safe switching without modification. Installation is a moderate DIY job for anyone comfortable working around electrical components: shut off all power at the disconnect, photograph and transfer the wiring one lead at a time, and secure the new unit. Always verify voltage and coil rating against your old part before powering up. Backed by genuine Carrier quality for long service life. In stock and ships same-day when your order is placed before 3PM CST, so you can get your AC running again fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model C48A502511.\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":62965544288627,"sku":"carrier-contactor-c48a502511","price":74.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-c48a502511","provider":"National HVAC Parts","version":"1.0","type":"link"}
