This is a safety-critical high-limit \/ rollout switch that opens the control circuit and shuts down the burner if it senses overheating or flame rollout. Because it is a \u003cem\u003emanual\u003c\/em\u003e reset, it stays tripped until pressed — a deliberate design that forces a technician to inspect the cause before the furnace can fire again. A furnace that trips out and won't restart often needs this switch replaced.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: manual-reset thermal limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eAction: normally closed, opens on overtemp\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10123529\u003c\/li\u003e\n\u003cli\u003ePrimary fit: Goodman WFD18115S5CXCB furnace\u003c\/li\u003e\n\u003cli\u003eFunction: high-limit \/ flame-rollout safety cutout\u003c\/li\u003e\n\u003cli\u003eTerminals: quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip temperature and reset behavior of a safety switch are not places to guess. The \u003cstrong\u003eOEM Goodman 10123529\u003c\/strong\u003e is calibrated to the exact cutout point the WFD18115S5CXCB engineers specified.
