This board governs the defrost cycle — monitoring the defrost thermostat and timer to reverse the system, energize the reversing valve, and clear frost from the outdoor coil, then return to normal operation. Symptoms of a failed board include a coil that ices over, a unit that never defrosts (or defrosts constantly), no outdoor fan operation, or a system that won't switch modes.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e PCBDM101S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Defrost timing and cycle control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Timing:\u003c\/strong\u003e Typical 30\/60\/90 minute jumper options\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e Defrost thermostat, reversing valve, fan relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMT070-3 and compatible units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM PCBDM101S is pin-and-terminal compatible with your existing harness and pre-configured to Goodman's defrost logic.
