This safety switch monitors temperature and opens the control circuit to shut down the burners if the furnace overheats or a flame rollout condition occurs. Because it is a manual reset device, it must be physically reset after a trip — a deliberate safety feature that flags an underlying fault. A failed or nuisance-tripping switch is a common cause of no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 10123517\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GCV91155DXBA and compatible furnace models\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature and flame-rollout protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman switch is calibrated to the exact trip temperature the furnace was engineered for.
