Overview

This OEM defrost control board (part number 34332101) is the brain of the defrost cycle in your ICP Tempstar Heil YJ036G heat pump. In heating mode, frost builds on the outdoor coil and must be periodically melted off so the system keeps absorbing heat. The defrost board monitors the defrost thermostat and run time, then commands the reversing valve and fan to run a timed or demand defrost, restoring efficiency. When this board fails, the heat pump can ice over completely, run continuously without defrosting, defrost too often, or lose backup-heat staging. Symptoms include a frozen outdoor unit, weak heating, and short cycling. This is a direct OEM-spec replacement board.

Frequently Asked Questions

Does this Control Board fit my ICP YJ036G — Heat Pump Timer | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP YJ036G — Heat Pump 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 YJ036G — Heat Pump 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?
