This normally-closed thermal safety control monitors heat-exchanger temperature and de-energizes the gas valve if the furnace overheats — protecting your equipment and home from unsafe operating conditions. A failed or nuisance-tripping limit switch is a common cause of a furnace that short-cycles, blows cold air, or locks out entirely.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003eFitment: Goodman\/Amana AMES921004CNAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM version\u003c\/strong\u003e is the exact factory-specified switch with the correct trip point and mounting geometry — the safest choice for a life-safety control.
