ICP Defrost Control Board for YG060GC1 — OEM Heat Pump Board | Ships Today

Overview

This OEM defrost control board (part #34332101) is the genuine ICP replacement for the YG060GC1 heat pump. The defrost board is the brain of heat-pump defrost operation — it monitors coil temperature and run time, then reverses the unit and shuts off the outdoor fan to melt frost from the outdoor coil before returning to heating. A failed defrost board leaves the outdoor coil iced over, kills efficiency, and can cause the unit to short-cycle or stop heating entirely. Replacing the board restores correct defrost timing and protects the compressor.

Specifications

Compatibility

Engineered for the ICP / Tempstar / Heil YG060GC1 heat pump. This OEM board matches the factory connector layout and defrost logic for that unit. Match the part number on your existing board before ordering, as defrost boards are model-specific.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the service panel to expose the control board.
3. Document — Photograph every harness plug, the defrost sensor lead, and any jumper/timer settings before disconnecting.
4. Remove — Unplug the harnesses, release the standoffs or screws, and lift the old board out.
5. Install — Snap the new board onto the standoffs, reconnect each harness per your photo, and set the defrost timer jumper to match the original.
6. Test — Restore power, initiate a defrost test, and confirm the reversing valve shifts and the outdoor fan cycles correctly.
