This manual-reset thermal cutout (commonly a rollout or auxiliary safety limit) opens permanently when it detects excessive heat — such as flame rollout from a cracked heat exchanger or a blocked flue — and must be pressed to reset once the fault is corrected. Because it requires a manual reset, it forces a technician to investigate the underlying problem rather than allowing repeated unsafe cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 10123529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual (push-button)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMH80453AXCA (80% AFUE gas furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, opens on rise (latching)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eManual-reset safety limits are the furnace's last line of defense against flame rollout and overheating.
