Built as a direct factory replacement for Carrier model CP48P448P409011CP, it is calibrated to the exact inches-of-water-column setpoint your unit needs, ensuring combustion byproducts vent safely. Symptoms of a faulty switch include no ignition, repeated safety lockouts, or an inducer that runs while the burner never lights. Installation is relatively easy: remove the hose and electrical terminals, swap in the new switch, and reconnect. Many handy homeowners finish in minutes, though a technician should verify proper draft pressure afterward. Choosing the correct OEM switch guarantees the right pressure rating and port configuration, avoiding the nuisance lockouts caused by generic parts. Each switch is tested to factory tolerance before shipment. Order before 3PM CST for same-day shipping and get your system heating again quickly.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model CP48P448P409011CP.\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":62961401790835,"sku":"carrier-pressure-switch-cp48p448p409011c","price":44.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-cp48p448p409011cp","provider":"National HVAC Parts","version":"1.0","type":"link"}
