This thermally activated switch opens the ignition\/gas circuit if it senses an over-temperature or flame-rollout condition, shutting the furnace down to prevent damage and hazard. Because it is a manual-reset device, it must be pressed to reset after tripping — a deliberate safety feature that forces inspection before the furnace runs again. If your furnace repeatedly locks out on limit, this is a common replacement part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 10123539\u003c\/li\u003e\n\u003cli\u003eType: Manual-reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature and flame-rollout cutoff\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMES921005CNAA furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM limit switches are calibrated to the exact trip temperature the furnace was engineered around, mount to the factory bracket, and use the correct terminal orientation. Generic switches with a different trip point can nuisance-trip or, worse, fail to protect — never a place to cut corners.
