This normally-closed thermal 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 \u003cstrong\u003emanual-reset\u003c\/strong\u003e device, it must be physically reset (button) after tripping — a deliberate design that forces a technician to diagnose the root cause (blocked flue, cracked heat exchanger, restricted airflow) before the furnace can run again.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual-reset thermal limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed (opens on over-temperature)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman WFM18090S4BXCB and compatible models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e High-limit \/ flame-rollout overheat protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM switch\u003c\/strong\u003e is factory-calibrated to the exact trip temperature specified for this furnace.
