Overview

This OEM defrost control board (part number 1173636) manages the defrost cycle on your Tempstar T2H336GKD200 heat pump. During heating, frost accumulates on the outdoor coil; the board watches the defrost thermostat and a timed interval, then briefly reverses the system and stops the outdoor fan to clear the ice before resuming heat. It also sequences the reversing valve and compressor relay logic. A failed board leaves the unit either never defrosting — icing up and losing capacity — or trapped in a continuous defrost loop that blows cold air and wastes energy.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker; verify zero voltage at the board with a multimeter.
Access — Remove the condenser unit's electrical access panel.
Document — Photograph every connector, jumper, and timer pin setting on the old board.
Remove — Unplug each harness, free the mounting standoffs or screws, and lift the board out.

Test — Restore power, run a heating call, and confirm normal operation plus a clean forced-defrost cycle.

Frequently Asked Questions

Does this Control Board fit my Tempstar T2H336GKD200 — 24V Heat Pump Board | Ships Today?

Yes. This is the factory-specified OEM control board for the Tempstar T2H336GKD200 — 24V 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 T2H336GKD200 — 24V 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.
