The defrost control board governs the timing and execution of the defrost cycle, monitoring outdoor coil temperature and initiating defrost mode to melt frost and ice accumulation on the evaporator coil. When this board fails, symptoms typically include the outdoor unit icing over completely, the system failing to enter defrost mode at all, erratic short-cycling between heating and defrost, or a heat pump that blows cold air during heating season due to a frost-locked coil.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM Part # HK32EA007 | Replaces cross-references 1173636 \u0026amp; 1177927 | Direct plug-and-play board swap | Factory-calibrated defrost timing and temperature thresholds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM board — not an aftermarket clone.
