In heat-pump mode this board manages the timed\/temperature defrost cycle, energizes the reversing valve, and coordinates the outdoor fan and auxiliary heat so the outdoor coil sheds frost without dumping cold air indoors. A failed defrost board is a common cause of an iced-over outdoor coil, no-defrost complaints, or a heat pump that will not switch between heating and cooling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: PCBDM101S\u003c\/li\u003e\n\u003cli\u003eFunction: Defrost timing \u0026amp; reversing valve control\u003c\/li\u003e\n\u003cli\u003eSelectable defrost intervals (board-set jumpers)\u003c\/li\u003e\n\u003cli\u003eEquipment: Heat Pump (packaged)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman APH1548M41AA and compatible units\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine PCBDM101S carries the correct defrost logic, relay ratings, and jumper\/timing configuration validated by Goodman for this platform.
