Overview

This is a genuine OEM defrost control board (part number 1069364) for the ICP/Tempstar/Heil YL036GA1 heat pump. The defrost control board is the brain of a heat pump's outdoor unit during heating season. It monitors coil temperature and run time, then initiates and terminates the defrost cycle to clear frost and ice from the outdoor coil. It also coordinates the reversing valve, the outdoor fan, and the auxiliary/emergency heat call so the system melts ice without blowing cold air into the home. When this 24V control fails, the unit may ice over solid, run constant or no defrost cycles, fail to switch between heating and cooling, or trip the system entirely.

Frequently Asked Questions

Does this Control Board fit my ICP YL036GA1 — 24V Heat Pump Board | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP YL036GA1 — 24V Heat Pump Board | 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 YL036GA1 — 24V Heat Pump Board | 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?
