Overview

This OEM defrost control board (part number 1173636) governs the defrost cycle on your ICP / Heil / Tempstar WCH5244GKA100 heat pump. It monitors coil temperature and accumulated run time, then commands the unit into and out of defrost so ice cannot build on the outdoor coil during heating. The board coordinates the reversing valve, compressor contactor, outdoor fan, and auxiliary heat hand-off. A failed defrost board lets the coil ice over, traps the unit in continuous defrost, causes short-cycling, or prevents proper heating/cooling switching. This factory-specification board restores correct 24V control logic and defrost timing.

Frequently Asked Questions

Does this Control Board fit my ICP WCH5244GKA100 — Heat Pump Timer Board | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WCH5244GKA100 — Heat Pump Timer 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 WCH5244GKA100 — Heat Pump Timer 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?
