Built to Carrier's factory specifications, it offers the correct coil voltage, pole count, and contact rating for model C48A402551, delivering safe, consistent switching and a service life that aftermarket replacements seldom match. When a contactor wears out, the most common results are a unit that won't start, a steady hum, contact chatter, or short cycling — all resolved by fitting the proper OEM part. For an experienced technician, replacement takes roughly 20-30 minutes: shut off power, move the wiring one lead at a time, and secure the new contactor in place. Since this is high-voltage work, we strongly recommend installation by a licensed HVAC professional. We keep this part in stock and ship same day on every order placed before 3PM CST, getting your system back online with minimal delay. Choose the contactor engineered specifically for your Carrier equipment and avoid repeat breakdowns.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model C48A402551.\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":62965781987699,"sku":"carrier-contactor-c48a402551","price":49.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-c48a402551","provider":"National HVAC Parts","version":"1.0","type":"link"}
