Overview

This genuine ICP defrost control board (OEM part 34332101) is the brain that manages the defrost cycle on your YK024G2 heat pump. Using the defrost thermostat and an internal timer, it decides when to reverse the system, shut off the outdoor fan, and clear frost from the outdoor coil, then returns the unit to normal heating. A failed defrost board lets ice build up on the coil — choking airflow and slashing heating capacity — or it can lock the unit into constant defrost. Because the board also routes the 24V control and reversing-valve signals, a fault here can mimic many other failures.

Frequently Asked Questions

Does this Control Board fit my ICP YK024G2 — Heat Pump Timer | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP YK024G2 — 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 YK024G2 — 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.
