OEM Carrier Fan Blower Control Board HK61EA002 for Model FC4BNF033000AEAA

This OEM fan blower control board (part number HK61EA002) is the factory-specified replacement for the Carrier FC4BNF033000AEAA fan coil air handler. The integrated fan control (IFC) board orchestrates all blower motor operations — managing speed staging, delay-on and delay-off timing, and communicating with the thermostat's 24V control circuit. When this board fails, common symptoms include the blower fan not starting, running at the wrong speed, operating continuously regardless of thermostat demand, or triggering a system lockout with no clear cause.

  • Specs: OEM part number HK61EA002 | 24V control circuit compatible | Multi-speed blower motor control | Factory-programmed timing sequences for Carrier FC4BNF033000AEAA fan coil units
  • OEM vs Generic: This is a genuine Carrier OEM board with factory-programmed logic — not an aftermarket substitute. Generic control boards frequently ship with incorrect timing parameters, mismatched speed taps, or incompatible fault-detection thresholds that can damage connected motors or void system warranties.
  • Install difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, smartphone (photograph all wiring harness connections before removal). Transfer wiring harnesses one connector at a time to avoid miswiring. Confirm 24V signal at the board terminals after reinstallation before restoring full power.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our climate-controlled warehouse in original manufacturer packaging.

Compatibility: Designed as a direct drop-in replacement for the Carrier FC4BNF033000AEAA fan coil air handler. Verify your existing board's part number against HK61EA002 and inspect your unit's data plate before ordering to confirm fitment. If you're unsure, our HVAC parts specialists verify compatibility at no charge before your order ships — reach out via chat or phone.

How do I replace the control board on my Carrier OEM Carrier Fan Blower Control Board HK61EA002 — FC4BNF033000AEAA?
Difficulty: Advanced (1–2 hrs)

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.
