Clipped to the outdoor coil, this bimetal switch tells the defrost control board when the coil has iced over in heating mode and when it has cleared, terminating the defrost cycle. A failed defrost thermostat is one of the most common reasons a heat pump ices up solid in winter or runs endless, energy-wasting defrost cycles.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0130M00105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Defrost \/ coil thermostat sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Bimetal snap-disc, clip-mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Initiates\/terminates defrost cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e ASZ130421AD (3.5-ton heat pump)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Push-on spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM thermostat is calibrated to Goodman's exact close\/open temperature setpoints, so defrost timing matches the control board's logic. Generic snap discs with slightly different trip points can cause short-cycling or incomplete defrosts.
