ICP Defrost Control Board for YG030GA2 — Heat Pump Timer Board | Ships Today

Overview

This OEM defrost control board (Part #1069364) manages the defrost cycle on your ICP heat pump model YG030GA2. It monitors outdoor coil temperature and accumulated run time, then starts and ends the defrost cycle to keep the outdoor coil clear of frost and ice during heating. A failed 24V board can leave the unit locked in defrost, unable to defrost (icing the coil solid), short-cycling, or unresponsive to the thermostat. Typical failure signs include a frozen outdoor unit, the reversing valve not energizing, repeatedly blown low-voltage fuses, or no heat-pump response. Installing a new defrost control board restores dependable, efficient heat-pump operation.
