This safety control monitors temperature in the furnace and opens the circuit to shut off the burners if it detects an overheat condition — typically caused by restricted airflow, a dirty filter, or blower failure. Once temperatures return to normal, the auto-reset contacts close and restore operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20269903\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary limit switch, automatic reset\u003c\/li\u003e\n\u003cli\u003eFunction: High-temperature overheat safety cutoff\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMV81155CXA and related furnaces\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20269903 is calibrated to Goodman's exact trip and reset temperatures, so it protects the heat exchanger without nuisance tripping.
