Overview
The defrost control board (OEM part number 34332101) is the brain of the defrost cycle on your ICP/Tempstar/Heil YG036GC2 heat pump. It monitors coil temperature and run time, then commands the reversing valve and outdoor fan to clear frost and ice from the outdoor coil during cold-weather operation. A failed defrost board is one of the most common causes of a heat pump that ices over, short cycles, or stops heating. This is a genuine OEM replacement built to the exact specifications of the original board, ensuring correct defrost timing and reliable communication with the rest of the system.

Compatibility
Designed as a direct-fit replacement for the ICP/Tempstar/Heil YG036GC2 heat pump. The 34332101 board is shared across many ICP-family condensing units of the same generation — verify your existing board's part number against 34332101 to confirm fitment before installing.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter at the board.
- Access — Remove the outdoor unit's control-panel service cover.
- Document — Photograph every wire and terminal connection on the old board before disconnecting anything.
- Remove — Label and unplug all connectors, release the mounting standoffs/screws, and lift out the failed board.
- Install — Seat the new board on the standoffs and reconnect each wire exactly as photographed.
- Test — Restore power and confirm normal operation; force a defrost cycle if needed to verify reversing-valve and fan response.
