This safety-critical component monitors furnace temperature and cuts power to the gas valve when it senses dangerous overheating — protecting the heat exchanger, wiring, and cabinet from heat damage. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e switch, it must be pressed to restore operation after a trip, prompting the homeowner or technician to investigate the root cause (dirty filter, blocked airflow, or failing blower).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 10123529\u003c\/li\u003e\n\u003cli\u003eType: Manual Reset High-Limit Switch\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat safety cutout\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMP100-42AA and related furnace models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman 10123529\u003c\/strong\u003e is calibrated to the exact trip temperature your furnace's control board and heat exchanger expect.
