Overview

This genuine OEM defrost control board (part number 34332101) governs the defrost cycle on the ICP/Heil/Tempstar YG024G heat pump. During heating operation the outdoor coil collects frost; this board reads the coil temperature sensor and tracks compressor run time, then periodically commands a defrost to melt that frost and keep the heat pump efficient. It coordinates the reversing valve, the compressor contactor, the outdoor fan, and the defrost timing intervals. When the board fails you may find the outdoor coil fully iced over, a system that never defrosts (or defrosts far too often), missing auxiliary heat staging, or a unit that won't change between heating and cooling. Because this single board controls so many functions, one failure can imitate several separate component faults – making the defrost board a high-value diagnostic and replacement part.

Frequently Asked Questions

Does this Control Board fit my ICP YG024G – Heat Pump | Ships Today?
Yes. This is the factory-specified OEM control board for the ICP YG024G – Heat Pump | Ships Today. 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 ICP YG024G – Heat Pump | Ships Today?
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 ICP 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 ICP 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?
