Overview

Genuine OEM defrost control board for the Tempstar T2H324GKD200 heat pump. The defrost board monitors the outdoor coil temperature sensor and run time, then initiates and terminates the defrost cycle — reversing the valve, shutting off the outdoor fan, and energizing auxiliary heat to keep ice off the outdoor coil in heating mode. A failed board causes a coil that ices over, a heat pump that never defrosts (or defrosts constantly), or a unit that won't run at all. Specs: 24V defrost control logic, OEM part 1173636.

Frequently Asked Questions

Does this Control Board fit my Tempstar T2H324GKD200 — OEM Heat Pump Board | Ships Today?

Yes. This is the factory-specified OEM control board for the Tempstar T2H324GKD200 — OEM Heat Pump 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 Tempstar T2H324GKD200 — OEM Heat Pump 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 Tempstar 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 Tempstar 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.
