Overview

This OEM defrost control board (part number 1173636) is the brain of the defrost cycle on your Tempstar T2H360GKA100 heat pump. It monitors outdoor coil temperature and run time, then commands the reversing valve and shuts off the outdoor fan to melt frost from the coil during cold-weather operation. When this board fails, the heat pump can ice over solid, run continuous defrost, or never defrost at all — both conditions kill efficiency and can damage the compressor. The board operates on a 24V control circuit and includes the time/temperature logic, defrost relay, and terminal connections needed to coordinate the unit's heating sequence.

Compatibility

Designed as a direct OEM replacement for the Tempstar T2H360GKA100 heat pump and shared across many ICP-family condensers built under the Tempstar, Heil, Comfortmaker, and Arcoaire brands that use the 1173636 board. Always confirm your existing board's part number before ordering.

Installation Guide

  1. Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter before touching any wiring.
  2. Access — Remove the control-panel service cover on the condenser cabinet.
  3. Document — Photograph every wire and terminal on the old board before disconnecting anything.
  4. Remove — Unplug the low-voltage and sensor connectors, release the board's mounting standoffs or screws, and lift out the failed board.
  5. Install — Mount the new 1173636 board, then reconnect each wire to the matching terminal using your photos.
  6. Test — Restore power, run a heating cycle, and confirm the unit enters and clears a defrost cycle normally.

Signs You Need a Replacement

  • Outdoor coil ices over and never clears during heating.
  • Unit gets stuck in continuous defrost or short-cycles the reversing valve.
  • No 24V output to the defrost relay or fan circuit.
  • Visible burn marks, swollen relays, or corroded traces on the board.

Frequently Asked Questions

Does this Control Board fit my Tempstar T2H360GKA100 — Heat Pump Demand Defrost | Ships Today?
Yes. This is the factory-specified OEM control board for the Tempstar T2H360GKA100 — Heat Pump Demand Defrost | 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 T2H360GKA100 — Heat Pump Demand Defrost | 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.
How fast does National HVAC Parts ship?
