Overview
This is the genuine OEM defrost control board (part number 1173636) for the Tempstar TXH560GKA200 heat pump. The defrost control board is the brain of the outdoor unit's defrost cycle — it monitors coil temperature and run time, then initiates and terminates defrost to clear frost and ice from the outdoor coil during heating operation. It also manages the reversing valve, compressor contactor, and outdoor fan timing. When this board fails, the heat pump can ice over, lose heating capacity, short-cycle, or fail to switch between heating and cooling modes. Installing a correct OEM defrost board restores reliable, efficient cold-weather performance.

Compatibility
This defrost control board is a direct OEM fit for the Tempstar TXH560GKA200 heat pump and shares the ICP/Heil platform, so it also services equivalent Heil, Comfortmaker, and ICP-built units that originally used part 1173636. Always confirm the part number on your existing board before ordering.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter at the control board terminals.
- Access — Remove the outdoor unit's electrical service panel to expose the control board.
- Document — Photograph every wire and connector position before disconnecting anything.
- Remove — Label and unplug the low-voltage and line-voltage connectors, release the board's mounting standoffs or screws, and lift out the old board.
- Install — Mount the new 1173636 board on the same standoffs and reconnect every wire exactly per your photos, confirming defrost sensor and reversing valve leads.
- Test — Restore power and verify the unit runs in heating and cooling, then force or observe a defrost cycle to confirm proper operation.
Signs You Need a Replacement

- Heat pump won't switch between heating and cooling modes.
- Compressor or outdoor fan short-cycles or won't energize.
