OEM Carrier Rectifier Control Board HK61EA003 for Model KFCEH3301C20

This OEM rectifier control board (part number HK61EA003) is the factory-specified replacement for the Carrier KFCEH3301C20 electric heat kit. The rectifier control board manages the conversion and regulation of electrical signals throughout the system, orchestrating sequencer timing, safety circuit monitoring, and communication between the thermostat and heating elements. When this board fails, you may experience symptoms such as no heat output, system lockout codes, erratic cycling, tripped breakers, or a complete loss of system response despite the thermostat calling for heat.

Specs: OEM part number HK61EA003 | Rectifier control board | Factory-matched input/output voltages | Direct drop-in replacement with original mounting footprint and terminal configuration
OEM vs Generic: This is a genuine Carrier OEM board, manufactured to exact factory tolerances. Aftermarket control boards may lack proper rectifier calibration, leading to premature sequencer failure, nuisance lockouts, and voided equipment warranties — making OEM the only reliable choice for this application.
Install difficulty: 3/5 — Disconnect all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, camera or phone for photographing all wire harness connections prior to removal. Label every connector before disconnecting. Allow capacitors to fully discharge before handling the board.
Warranty: 1-year OEM factory warranty against defects. Orders placed by 3 PM local time ship same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier KFCEH3301C20 electric heat kit. Verify OEM part number HK61EA003 against your unit's data plate or existing board label before ordering.

Frequently Asked Questions

Does this Control Board fit my Carrier KFCEH3301C20?

Yes. This is the factory-specified OEM control board for the Carrier KFCEH3301C20. 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 KFCEH3301C20?

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.
