Overview
The 1069364 Defrost Control Board is the OEM control that manages the defrost cycle on the ICP / Tempstar / Heil YG024GC9 heat pump. It tracks outdoor coil temperature and compressor run time, then commands a defrost when ice builds on the outdoor coil — energizing the reversing valve, dropping the outdoor fan, and signaling auxiliary heat so supply air stays warm. It also coordinates the compressor contactor during normal operation. A failed board leaves the coil to freeze solid, causes erratic or constant defrosts, or kills heating entirely. This is a direct OEM replacement matched to the YG024GC9's terminal layout and defrost timing, ensuring the system protects itself in cold weather exactly as designed.

Compatibility
Built for the ICP Tempstar Heil YG024GC9 heat pump and ICP-family outdoor units that shipped with defrost board 1069364. Confirm the printed part number on your current board before ordering, since ICP used several defrost boards across model years.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the outdoor unit's control-panel service cover.
- Document — Photograph every wire and terminal position before disconnecting.
- Remove — Unplug the low-voltage harness, sensor leads, and high-voltage terminals, then unscrew the old board from its standoffs.
- Install — Mount the new 1069364 board, reconnect each wire per your photos, and firmly seat the defrost sensor lead.
- Test — Restore power, run a heating cycle, and observe a defrost to confirm the reversing valve and fan respond.
Signs You Need a Replacement
