Mounted near the burner box, it senses abnormal heat caused by flame rollout — typically from a cracked heat exchanger, blocked flue, or restricted combustion air — and opens the gas-valve circuit to shut the furnace down. Because it is a \u003cem\u003emanual\u003c\/em\u003e reset device, it will not automatically re-close, forcing a technician to inspect the cause before restoring heat.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 10123533\u003c\/li\u003e\n\u003cli\u003eType: Manual reset flame rollout \/ limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed, opens on overtemp\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS90453BXAD gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM switch\u003c\/strong\u003e carries the correct factory trip temperature and reset behavior matched to this furnace's burner geometry.
