OEM Carrier Control Board Replacement for Model FA4ANF018008AGAA

This authentic OEM Carrier control board is the brain of your FA4ANF018008AGAA fan coil unit, directing blower speed, enforcing safety interlocks, and handling thermostat and outdoor-unit communication. It interprets sensor data and outputs diagnostic codes that keep heating and cooling cycles precise. A bad board often shows up as dead airflow, random cycling, or no LED activity—this direct-fit replacement resolves those issues and brings the system back to normal operation. Manufactured to Carrier specifications, it installs into the FA4ANF018008AGAA without modification, lining up exactly with factory connectors and mounts. Expect a moderate installation best left to a licensed HVAC professional working on a de-energized unit; about 30–45 minutes, and photograph the wiring first. Genuine Carrier components deliver the correct logic and durability that aftermarket boards can't guarantee. Order before 3PM CST for same-day shipping and minimal downtime. Reach out anytime and we'll confirm this board matches your equipment before you buy.

Frequently Asked Questions

Does this Control Board fit my Carrier Model FA4ANF018008AGAA?
Yes. This is the factory-specified OEM control board for the Carrier Model FA4ANF018008AGAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier Model FA4ANF018008AGAA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
