Overview

OEM part 1173636 is the genuine defrost control board for the ICP / Tempstar / Heil WCH5184GKA200 heat pump. This board is the brain of heat-pump operation: it monitors the outdoor coil temperature sensor, runs the defrost timer logic, and decides when to reverse the system into a defrost cycle to melt frost off the outdoor coil. It also coordinates the reversing valve, condenser fan, and the 24V control signals to the indoor unit. A failed defrost board commonly shows up as a heat pump that ices over in winter, never defrosts, defrosts too often, or loses heating output entirely.

Compatibility

Designed as the factory defrost control board for the ICP / Tempstar / Heil WCH5184GKA200 heat pump and same-platform ICP-family outdoor units using this board. Match your existing board part number and connector layout before ordering, as defrost boards are model-specific.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the control panel with a multimeter.
Access — Remove the outdoor unit control-box service panel.
Document — Photograph every plug, wire, and terminal on the old board before removing anything.
Remove — Unplug each connector, release the board standoffs or screws, and lift out the failed board.
Install — Seat the new board on its standoffs and reconnect each connector to the matching position per your photo.
Test — Restore power, run a heat-pump heating call, and confirm normal operation and a clean defrost cycle.

Frequently Asked Questions

Does this Control Board fit my ICP WCH5184GKA200 — 24V Heat Pump | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP WCH5184GKA200 — 24V 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 WCH5184GKA200 — 24V 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.

How fast does National HVAC Parts ship?
