Featuring a 7-inch sensing element and a 240°F trip point, this switch monitors heat-exchanger temperature and shuts off the gas valve if the furnace overheats — protecting against blower failures, restricted airflow, and dirty filters. A failed limit switch commonly causes no-heat, intermittent lockouts, or nuisance shutdowns.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 240°F (auto-reset high limit)\u003c\/li\u003e\n\u003cli\u003eProbe length: 7 inches\u003c\/li\u003e\n\u003cli\u003eType: Bimetal SPST high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eMount: Two-screw flange to heat-exchanger panel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMPV125-5 and select Amana gas furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370912S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370912S\u003c\/strong\u003e guarantees the exact 240°F set point, 7-inch probe depth, and flange pattern required for safe, code-compliant operation.
