This safety control opens the gas valve circuit when it senses abnormal heat or flame rollout at the burner box, shutting the furnace down to prevent overheating. Unlike auto-reset controls, this switch stays open until manually reset — a deliberate safety feature that forces a technician to diagnose the root cause before the unit restarts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset limit \/ flame rollout switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDH80403ANAA 80% gas furnace\u003c\/li\u003e\n\u003cli\u003eFunction: High-limit safety cutout, opens on overheat\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur genuine \u003cstrong\u003eOEM 10123529\u003c\/strong\u003e is calibrated to the exact factory trip temperature for your furnace, guaranteeing proper safety operation and preserving your equipment warranty.
