Overview

This genuine OEM defrost control board (part #1069364) is the brain of the ICP/Tempstar/Heil YG036GA1 heat pump's defrost cycle. The board monitors the defrost thermostat and run time, then commands the reversing valve, condenser fan, and auxiliary heat to clear frost from the outdoor coil during cold-weather operation. It also manages compressor timing and anti-short-cycle protection. When this board fails, the heat pump may ice over and lose heating capacity, run defrost cycles too often or never, fail to switch to backup heat, or leave the outdoor fan running when it shouldn't. Because the board carries both 24V control logic and switching relays, a failed board typically disables proper heating-mode operation entirely.

Frequently Asked Questions

Does this Control Board fit my ICP YG036GA1 — Heat Pump | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP YG036GA1 — 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 YG036GA1 — 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?
