This normally-closed thermal safety control opens the gas valve and burner circuit if the heat exchanger temperature exceeds its \u003cstrong\u003e210°F\u003c\/strong\u003e trip point, protecting your furnace from overheating, cracked heat exchangers, and dangerous operation. It is a critical safety component — a failed or bypassed limit switch is one of the most common causes of no-heat and short-cycling calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 210°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit \/ thermal cutout\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMS80453AXA and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370190\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003egenuine OEM B1370190\u003c\/strong\u003e is calibrated to Goodman's exact 210°F specification and mounting footprint, ensuring correct trip timing and a drop-in fit.
