This normally-closed thermal switch opens the ignition circuit and shuts down the burners if it senses flame rollout or excessive temperature at its mounting location — protecting the heat exchanger and household from unsafe over-temperature conditions. Once tripped, it must be manually reset (press the button) after the fault is diagnosed and cleared, which is exactly how a safety-critical limit should behave.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123519\u003c\/li\u003e\n\u003cli\u003ePart Type: Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eContact Configuration: Normally closed (opens on over-temp)\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button reset\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GMH951155DXAD and related GMH95 series furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact cutout temperature this furnace requires. Generic limit switches may use a different trip point or terminal orientation, which can cause nuisance shutdowns or, worse, fail to protect at the correct temperature.
