Overview
This is the OEM defrost control board (part number 1069364) for the ICP / Tempstar / Heil YJ060GB1 heat pump. The defrost control board is the brain of the outdoor unit's heat-pump cycle. It monitors coil temperature and run time, then commands the reversing valve and outdoor fan to periodically melt frost off the outdoor coil during heating operation. It also manages compressor timing delays and safety lockouts. When this 24V board fails, the system loses its ability to defrost — frost and ice build up on the outdoor coil, heating capacity drops, and the compressor can short-cycle or lock out. Common failure symptoms include the outdoor unit icing over, no heat in heat-pump mode, the reversing valve not shifting, or the unit getting stuck in a continuous defrost cycle.

Compatibility
Designed as the factory replacement defrost board for the ICP Tempstar Heil YJ060GB1 heat pump. ICP manufactures under several badges, so this board services equivalent Tempstar, Heil, Comfortmaker, and other ICP-family condensing units that originally shipped with part 1069364. Always confirm your existing board part number before ordering.
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.
