Over time capacitors degrade, producing motor hum, hard or failed starts, overheating, and reduced airflow that forces the whole system to work harder. Installing a fresh, properly rated capacitor restores smooth motor performance and helps prevent costly motor burnout. Made to Carrier's exact microfarad and voltage specifications, this part fits the FX4ANF042000ACAA directly with no modification. The replacement is a moderate DIY job: turn off power at the breaker, discharge the old capacitor safely, snap a photo of the leads, transfer the wires, and secure the mounting strap in about 20 minutes. Genuine OEM parts ensure correct fit and full rated performance while preserving warranty coverage. In stock and ships same-day when you order before 3PM CST, getting your cooling back fast. While the access panel is open, check the contactor and wiring for wear.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FX4ANF042000ACAA.\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":62942896062835,"sku":"carrier-run-capacitor-fx4anf042000acaa","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-fx4anf042000acaa.jpg?v=1781472568","url":"https:\/\/nationalhvacparts.com\/products\/carrier-run-capacitor-fx4anf042000acaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
