The Goodman 0130M00105 Defrost Thermostat is a genuine OEM replacement for ASZ130241AC 13 SEER, 2-ton heat pump condensers and other compatible Goodman/Amana outdoor units. Clamped to the outdoor coil, this bi-metal sensor tells the defrost board when frost has built up on the coil and when it has cleared, ensuring your heat pump defrosts efficiently in cold weather without wasting run time or icing over.
When a defrost thermostat fails, the most common symptoms are a coil that ices completely over in winter, weak heating output, or a unit that runs defrost cycles far too often or not at all. Replacing this inexpensive part is one of the cheapest fixes for those problems.
Our genuine OEM 0130M00105 is calibrated to Goodman's exact close/open temperature spec, so your defrost board reads the coil correctly the first time. Generic bi-metal snap discs are cheaper but frequently trip at the wrong temperature, leading to short-cycling defrost or a frozen coil. For a part this affordable, OEM is the smart choice.
Easy — DIY friendly (15–20 min). Disconnect power, remove the clamp from the coil, unplug the two-wire connector, and reverse. No refrigerant handling required. Always confirm power is off at the disconnect before servicing.
