A weak or failed capacitor commonly causes a motor that buzzes but won't start, slow spin-up, overheating, or a system that won't move air through your home. Manufactured to Carrier's precise factory ratings, this dual-rated capacitor is a direct drop-in replacement for the FB4ANB042010ABAA, eliminating any uncertainty about microfarad or voltage values. Genuine OEM construction means tighter tolerances and a longer service life than bargain aftermarket units, protecting your motor from damaging voltage swings. Installation is DIY-friendly and typically takes 15-20 minutes with a screwdriver—just shut off power at the disconnect, discharge the old capacitor safely, and match the wiring (snap a photo first). It is an inexpensive, high-impact repair that often brings a dead air handler back to life. Orders placed before 3PM CST ship same-day so you avoid a long, hot wait. Stock a spare to stay ahead of peak-season failures.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FB4ANB042010ABAA.\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":62954779181427,"sku":"carrier-run-capacitor-fb4anb042010abaa","price":24.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-run-capacitor-fb4anb042010abaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
