Overview
This OEM defrost control board (part number 34332101) is the brain of the defrost cycle on your ICP Tempstar Heil YG060G heat pump. It monitors coil temperature and run time, then commands the unit into and out of defrost so frost cannot choke the outdoor coil during heating. Operating on 24V control voltage, the board sequences the reversing valve, outdoor fan, and auxiliary heat. When this board fails you will typically see the outdoor coil ice over, the unit stuck in defrost, no defrost at all, or erratic auxiliary-heat behavior. Replacing the board restores proper, efficient heat-pump operation.

- Test — Restore power and confirm normal heating, then force or wait for a defrost cycle to verify sequencing.
