OEM Carrier Rectifier Control Board HK61EA003 for Model KFCEH1801F20

This is the genuine OEM rectifier control board (part number HK61EA003), factory-specified for the Carrier KFCEH1801F20 electric heater kit. The rectifier control board serves as the central command module, managing power conversion and distribution to all downstream heating components. When this board fails, common symptoms include complete system lockout, intermittent heating, unresponsive controls, tripped breakers, or erratic staging behavior that cannot be resolved by thermostat adjustments or resetting the unit.

  • Specs: OEM Part Number HK61EA003 | Rectifier control board configuration | Factory-calibrated for Carrier KFCEH1801F20 electric heater kit | Designed to meet original equipment electrical load and sequencing requirements
  • OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM control boards use factory-programmed logic and components rated to exact tolerances. Generic boards frequently lack correct sequencing timing, increasing the risk of nuisance lockouts, component damage, and voided equipment warranties.
  • Install difficulty: 4/5 — Control board replacement requires disconnecting high-voltage wiring. Always shut off all power at the breaker before servicing. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter, camera or phone (photograph all wiring connections before removal). Professional installation recommended if you are unfamiliar with electric heater kits.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse — no waiting on special orders.

Compatibility: This board is engineered specifically for the Carrier KFCEH1801F20 electric heater kit. Verify your unit's model and data plate before ordering to ensure correct fitment. Our HVAC parts specialists are available to confirm compatibility before you purchase — reach out with your model and serial number for peace of mind. Order today and get your system back online fast.

Frequently Asked Questions

Does this Control Board fit my Carrier KFCEH1801F20?
Yes. This is the factory-specified OEM control board for the Carrier KFCEH1801F20. 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 KFCEH1801F20?
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?
