OEM Carrier Rectifier Control Board HK61EA003 for Model KFCEH2801C20

This is the factory OEM rectifier control board (part number HK61EA003) designed as the direct replacement for the Carrier KFCEH2801C20 electric heater kit. The rectifier control board manages the sequencing, safety logic, and power conversion functions that regulate electric heat operation within the air handler system. When this board fails, symptoms typically include complete loss of electric heat, intermittent heating cycles, tripped breakers with no clear cause, or the system entering a hard lockout with no error code resolution after reset.

  • Specs: OEM Part Number HK61EA003 | Rectifier control board configuration | Factory-matched for KFCEH2801C20 electric heater kit | Engineered to exact Carrier voltage, sequencing, and safety-cutout specifications
  • OEM vs Generic: OEM control boards carry factory-programmed logic and component tolerances specific to Carrier heater kits. Aftermarket boards frequently lack identical sequencer timing and protection thresholds, risking nuisance trips or, worse, undetected fault conditions.
  • Install Difficulty: 3/5 — Requires disconnecting line and low-voltage wiring from the existing board. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a phone camera to document all wiring positions before removal. Always shut off power at the breaker and verify with a multimeter before handling. If unfamiliar with electric heat sequencing, professional installation is recommended.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed by 3 PM local time ship same business day from our stocked warehouse.

Compatibility: This board is specified for the Carrier KFCEH2801C20 electric heater kit accessory. Always confirm the OEM part number HK61EA003 against your existing board's label and your unit's wiring diagram before ordering. Our fitment specialists are available to verify compatibility before you buy — no guesswork required. Order today and get same-day shipping on this in-stock OEM part.

Frequently Asked Questions

Does this Control Board fit my Carrier KFCEH2801C20?
Yes. This is the factory-specified OEM control board for the Carrier KFCEH2801C20. 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 KFCEH2801C20?
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?
