This board is the brains of the outdoor unit's heating operation — it monitors coil temperature, runs the timed\/demand defrost cycle, energizes the reversing valve solenoid, and coordinates the outdoor fan and compressor contactor so the unit sheds frost without dumping cold air into the home.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: PCBDM101S\u003c\/li\u003e\n\u003cli\u003eComponent: Integrated defrost control board\u003c\/li\u003e\n\u003cli\u003eEquipment: Split-system heat pump\u003c\/li\u003e\n\u003cli\u003eCompatible Model: ASH130181AB\u003c\/li\u003e\n\u003cli\u003eFunctions: Defrost timing, reversing valve, fan \u0026amp; compressor control\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eDefrost logic, jumper timing options, and terminal pin-out are model-specific. The \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e PCBDM101S is a plug-in match with the correct firmware behavior and relay ratings. Aftermarket boards can misread the defrost thermostat or mis-time the reversing valve, causing icing or no-heat calls.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eReplacement means labeling and transferring low- and line-voltage connections one at a time and setting the defrost timing jumper to match the original. Always kill power at the disconnect first. A handy DIYer can manage it, but wiring accuracy is critical.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058300207475,"sku":"GOODMAN-15937","price":58.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-defrost-control-board-for-ash130181ab-pcbdm101s","provider":"National HVAC Parts","version":"1.0","type":"link"}
