This switch monitors heat-exchanger temperature and interrupts the ignition sequence if the furnace overheats, protecting the equipment and your home. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it will not automatically re-close after a trip — a technician must inspect the cause and press the button to restore operation, which is exactly the fail-safe behavior the furnace's safety circuit is designed around.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit (temperature) switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123539\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat safety cutoff \/ flame rollout protection\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFit: Goodman \/ Amana furnaces including AMSS921005CNAA\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the \u003cstrong\u003egenuine OEM\u003c\/strong\u003e Goodman part, calibrated to the exact trip temperature specified for your furnace. Universal or generic limit switches often carry a different trip point or bracket geometry, which can cause nuisance shutdowns or, worse, fail to trip when needed. For a safety-critical component like this, we recommend the OEM part for guaranteed calibration and fit.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Typically a two-wire, single-screw replacement.
