OEM Carrier Rectifier Control Board HK61EA003 for Model EHK308B01

This is the genuine OEM rectifier control board (part number HK61EA003) designed as the factory-specified replacement for the Carrier EHK308B01 electric heater kit. The rectifier control board manages the conversion and regulation of electrical power within the heater kit assembly, coordinating sequencing, safety lockouts, and power delivery to the heating elements. When this board fails, you may experience a complete loss of heat output, tripped breakers, erratic sequencer behavior, or the unit failing to energize at all despite the thermostat calling for heat.

  • Specs: OEM part number HK61EA003 | Factory-matched rectifier control board | Designed for Carrier EHK308B01 electric heater kit | Exact-fit direct replacement for original board
  • OEM vs Generic: This is a genuine Carrier OEM board, manufactured to exact factory specifications. Generic or aftermarket control boards often lack proper tolerances, can cause nuisance tripping, void equipment warranties, and introduce safety risks in high-voltage electric heat applications. OEM is strongly recommended for rectifier boards.
  • Install Difficulty: 3/5 — Electric heater kits involve high-voltage wiring. Always disconnect and lock out power at the breaker before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter, camera or phone to document wiring before removal. If unfamiliar with high-voltage systems, consult a licensed HVAC technician.
  • Warranty: 1-year OEM factory warranty included. Order ships same business day from our warehouse when placed before cutoff.

Compatibility: Engineered specifically for the Carrier EHK308B01 electric heater kit. Always verify the part number printed on your existing board matches HK61EA003 before ordering.

Frequently Asked Questions

Does this Control Board fit my Carrier EHK308B01?
Yes. This is the factory-specified OEM control board for the Carrier EHK308B01. 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 EHK308B01?
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?
