When the board fails, you may experience a non-starting system, an unresponsive blower, flashing diagnostic codes, or erratic short-cycling. Engineered and programmed to Carrier's factory specifications, this authentic board is an exact match for the FA4CNC036008AAAA, so you avoid the compatibility and setup issues that come with generic universal boards. Replacing it with the correct OEM part restores reliable fan control, proper operating sequence, and the safety monitoring that protects your motor and heating components. Installation is rated moderate to advanced — most technicians finish in 30 to 45 minutes by moving wires one at a time, after photographing the layout and cutting power at the breaker. Because this is a true Carrier part, fit and performance are assured straight from the box. Place your order before 3PM CST and it ships the same day to minimize system downtime. Our parts team can confirm your exact board revision before purchase whenever you need it.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FA4CNC036008AAAA.\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":62955791548787,"sku":"carrier-control-board-fa4cnc036008aaaa","price":149.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-fa4cnc036008aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
