This temperature-sensing bimetal switch monitors heat-exchanger air temperature and cuts power to the gas valve if the furnace overheats — a critical safety component that prevents damage from restricted airflow, a dirty filter, or a failed blower. A furnace that short-cycles on heat or trips the limit is a classic sign this switch has drifted out of spec.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Snap-disc high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eApplication: Gas furnace heat-exchanger over-temperature protection\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WGGE4330A070MAB and compatible units\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10728342\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eChoose the \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch for a factory-matched trip temperature and mounting footprint — no guesswork on calibration.
