Overview

This is a genuine OEM defrost control board (part number 34332101) for the ICP/Tempstar/Heil YJ030G1 heat pump. The defrost board is the brain of the outdoor unit in heating mode: it monitors the defrost thermostat and time intervals, reverses the refrigerant cycle to melt frost off the outdoor coil, controls the reversing valve solenoid, and manages compressor and fan timing. Without a functioning board, the heat pump cannot defrost properly, leading to ice buildup, reduced heating capacity, and potential compressor damage.

Defrost boards typically fail from voltage surges, lightning, moisture intrusion, or simple age. Symptoms include the outdoor coil freezing over and staying iced, the unit getting stuck in defrost, no compressor operation in heat mode, or erratic relay clicking. Replacing the board restores correct defrost timing and reliable heat-pump operation through the cold season.

Frequently Asked Questions

Does this Control Board fit my ICP YJ030G1 — Heat Pump | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP YJ030G1 — 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 YJ030G1 — 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.
