This normally-closed safety device opens the ignition circuit if it detects excessive heat from flame rollout — a critical protection against blocked heat exchangers or restricted venting. Because it is manual-reset, a tripped switch signals an underlying condition that should be inspected before pressing the reset button.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 10123529\u003c\/li\u003e\n\u003cli\u003eType: Manual reset flame rollout limit switch\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (opens on high temp)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18090S5CXCB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: High-temperature safety shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact trip temperature the furnace was engineered around.
