OEM Carrier Rectifier Control Board HK61EA003 for Model KFCEH3501F30

This is the genuine OEM rectifier control board (part number HK61EA003), factory-specified for the Carrier KFCEH3501F30 electric heating kit. The rectifier control board manages the conversion and regulation of electrical signals that coordinate heating element sequencing, safety circuit monitoring, and system communication. When this board fails, common symptoms include complete loss of heat, erratic or intermittent heating cycles, tripped safety lockouts that won't reset, or a system that powers on but produces no output — all signs the control board is no longer orchestrating functions correctly.

  • Specs: OEM part number HK61EA003 | Rectifier control board | Factory-matched input/output ratings | Direct plug-and-play connector compatibility for KFCEH3501F30 electric heating kits
  • OEM vs Generic: This is a genuine Carrier OEM board, manufactured to exact factory tolerances. Aftermarket control boards frequently suffer from mismatched firmware logic, substandard relay ratings, and inconsistent safety circuit thresholds — risks not worth taking on a primary control component.
  • Install Difficulty: 3/5 — Disconnect all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter for voltage verification. Photograph all wiring harness connections before removal. Reattach connectors firmly and verify secure seating before restoring power.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier KFCEH3501F30 electric heating kit. Always cross-reference your existing board's part number against HK61EA003 and verify your unit's data plate specifications before ordering. Our HVAC parts specialists are available to confirm fitment — reach out before you buy for total peace of mind. Order today and your part ships the same business day.

Frequently Asked Questions

Does this Control Board fit my Carrier KFCEH3501F30?
Yes. This is the factory-specified OEM control board for the Carrier KFCEH3501F30. 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 KFCEH3501F30?
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?
