This safety control monitors temperature at the heat exchanger and opens the circuit to shut down the burners if the furnace overheats — protecting against cracked heat exchangers, restricted airflow, and fire hazards. Because it is a manual-reset design, it must be physically reset after a trip, alerting the homeowner or technician that an overheat condition occurred and needs diagnosis.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10123533\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual (press-to-reset button)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GKS90905DXAB (Goodman gas furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens burner circuit on over-temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine Goodman 10123533 is calibrated to the exact trip and reset temperature specified for the GKS90905DXAB, with the correct mounting flange and terminal layout.
