Overview
The OEM defrost control board (part number 1069364) is the electronic brain that manages the defrost cycle on your ICP YJ030GA2 heat pump. It monitors coil temperature and run time, then commands the reversing valve and supplemental heat to clear frost from the outdoor coil during heating mode. When this board fails, the outdoor unit can ice over, short-cycle, fail to switch between heating and cooling, or stop running entirely. A failed defrost board is one of the most common causes of a heat pump that freezes solid in winter or loses heating capacity. This is a genuine OEM replacement built to the exact timing and relay specifications of the original.

Compatibility
Engineered as a direct-fit replacement for the ICP / Tempstar / Heil YJ030GA2 heat pump and related YJ030 series condensing units that originally shipped with board 1069364. Always match the part number printed on your existing board before ordering.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, verify zero voltage with a multimeter.
- Access — Remove the control panel access cover on the condensing unit.
- Document — Photograph every wire and connector position on the old board before disconnecting anything.
- Remove — Label and unplug the low-voltage and line-voltage leads, release the board mounting standoffs or screws, and lift the old board out.
- Install — Seat the new 1069364 board on the standoffs and reconnect every wire exactly as shown in your photo.
- Test — Restore power and force a defrost cycle to confirm the reversing valve switches and the cycle terminates on temperature/time.
