Overview

This genuine OEM defrost control board (part number 1069364) is the brain of the defrost cycle on the ICP/Tempstar/Heil YG018GB2 heat pump. In heating mode, frost builds on the outdoor coil; the defrost board monitors time and temperature, then periodically reverses the system to melt that frost and protect efficiency. The board controls the reversing valve solenoid, the defrost relay, and the timing intervals, and coordinates with the outdoor coil sensor. A failed defrost board typically shows up as an iced-over outdoor coil in winter, a unit stuck in defrost, or a heat pump that won't switch between heating and cooling. Replacing the board restores correct defrost timing and full heat-pump performance.

Frequently Asked Questions

Does this Control Board fit my ICP YG018GB2 — Heat Pump Defrost Timer | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP YG018GB2 — Heat Pump Defrost Timer | 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 YG018GB2 — Heat Pump Defrost Timer | 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?
