Overview
This is the OEM defrost control board (part number 1069364) for the ICP / Tempstar / Heil YJ060GA2 heat pump. The defrost board governs the outdoor unit's heat-pump operation: it monitors outdoor coil temperature and accumulated run time, then periodically energizes the reversing valve and stops the outdoor fan to melt frost from the coil during heating. It also enforces compressor anti-short-cycle timing and safety lockouts. When this 24V board fails, the unit can no longer defrost — ice builds on the outdoor coil, heating output collapses, and the compressor may short-cycle or lock out. Typical symptoms include an iced-over outdoor unit, no heat in heat-pump mode, a reversing valve that will not shift, or a system stuck in perpetual defrost.

Compatibility
Factory replacement defrost board for the ICP Tempstar Heil YJ060GA2 heat pump and equivalent ICP-family condensing units that originally shipped with part 1069364.

Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter at the board terminals.
- Access — Remove the outdoor unit's control-access service panel.
- Document — Photograph every wire and connector at the board before disconnecting anything.
- Remove — Label and disconnect the low-voltage and line-voltage leads, release the board standoffs/screws, and lift out the old defrost board.
- Install — Mount the new 1069364 board on the same standoffs and reconnect every wire exactly as photographed, including the defrost thermostat sensor.
- Test — Restore power, set the system to heat, and confirm the unit initiates and terminates a defrost cycle and that the reversing valve and outdoor fan respond.
