This safety control monitors temperature in the heat-exchanger or burner area and opens the circuit if the furnace overheats — commonly caused by restricted airflow, a failed blower, or a blocked flue. Unlike an auto-reset limit, a manual-reset switch stays open until a technician presses the button, ensuring a genuine over-temperature fault is investigated rather than silently cycling. A tripped or failed limit is a frequent cause of no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: manual-reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: opens on overheat, requires manual reset\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18045S3AXCC furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10123529\u003c\/li\u003e\n\u003cli\u003eContacts: normally closed, opens on temperature rise\u003c\/li\u003e\n\u003cli\u003eMounting: bracket \/ probe style per original\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM Goodman switch is calibrated to the exact trip and reset temperature Goodman specified for this furnace, and its terminals and mounting match the harness and bracket.
