OEM Carrier Defrost Control Board HK32EA003 for Model PH16NA02400GBAAA

This is the OEM-specified defrost control board (part number HK32EA003) for the Carrier PH16NA02400GBAAA packaged heat pump. The defrost control board governs the timing and logic of defrost cycles, signaling the system to periodically reverse refrigerant flow to melt frost accumulation on the outdoor coil. When this board fails, you may observe continuous icing on the outdoor unit, a total loss of heating capacity in cold weather, a heat pump that runs in defrost mode continuously, or a system that never initiates a defrost cycle at all — all of which degrade efficiency and can cause compressor damage if left unaddressed.

  • Specs: Input Voltage: 18–30 VAC | Frequency: 50/60 Hz | Defrost duration: up to 10 minutes | Adjustable time intervals: 30 / 60 / 90 / 120 minutes | OEM part number: HK32EA003 | Cross-reference: CEBD430433-08A, CEPL130433-01, CES0130076-00
  • OEM vs Generic: OEM boards are factory-calibrated to Carrier's exact defrost timing specifications, ensuring precise cycle intervals and reliable relay switching. Generic alternatives may use off-tolerance components that cause erratic defrost behavior, premature coil icing, or nuisance lockouts.
  • Install Difficulty: 3/5 — Disconnect all power before beginning. Photograph all wiring connections prior to removal. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter for 24V control circuit verification. Note: HK32EA003 has been superseded by HK32EA008 — confirm board layout and connector positions match before installation.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse — no drop-ship delays.

Compatibility: Factory-specified defrost control board for the Carrier PH16NA02400GBAAA packaged heat pump. Also referenced as a Carrier and BDP defrost board compatible across multiple Carrier heat pump platforms using the CEPL130433-01 board configuration. Verify your existing board's part number and terminal layout before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — same-day shipping on all in-stock orders.

Frequently Asked Questions

Does this Control Board fit my Carrier PH16NA02400GBAAA?
Yes. This is the factory-specified OEM control board for the Carrier PH16NA02400GBAAA. 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 PH16NA02400GBAAA?
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?
