OEM Carrier Rectifier Control Board HK61EA003 for Model KFCEH0501N05

This OEM rectifier control board (part number HK61EA003) is the factory-specified replacement for the Carrier KFCEH0501N05 electric heat kit. The rectifier control board manages and regulates the electrical sequencing of the heating elements, converting and directing power to ensure safe, staged operation of the electric heat section. When this board fails, you may experience complete loss of heat, tripped breakers, erratic sequencer behavior, or fault codes that prevent the system from energizing the heating elements at all.

  • Specs: OEM Part Number HK61EA003 | Rectifier control board for electric heat kit | Factory-matched voltage and sequencing logic | Direct drop-in replacement — no modifications required
  • OEM vs Generic: This is a genuine Carrier OEM board, built to exact factory tolerances. Aftermarket control boards frequently ship with mismatched sequencing timing or incorrect rectifier ratings, leading to nuisance trips, element damage, or premature failure — all risks eliminated with the OEM part.
  • Install difficulty: 3/5 — Disconnect all power at the breaker before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter, phone or camera to photograph wiring harness before disconnection. Label all connectors prior to removal. If unfamiliar with high-voltage electric heat kits, professional installation is recommended.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier KFCEH0501N05 electric heat kit. Always verify your existing board's part number against HK61EA003 before ordering, and confirm voltage and amperage ratings on your unit's data plate. Our parts specialists are available to verify fitment before you purchase — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Control Board fit my Carrier KFCEH0501N05?
Yes. This is the factory-specified OEM control board for the Carrier KFCEH0501N05. 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 KFCEH0501N05?
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?
