This normally-closed thermal safety switch opens the control circuit and shuts down the burners if it senses an over-temperature or flame-rollout condition. Because it is a \u003cem\u003emanual-reset\u003c\/em\u003e device, it stays open after a fault until you physically press the reset button — a deliberate safety design that forces inspection before the furnace can fire again.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual-reset thermal limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (opens on high temperature)\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temp and flame-rollout safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18140S5DNCC and compatible models\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e switch is calibrated to the furnace's exact trip temperature and mounting footprint — critical for a safety component.
