This normally-closed switch opens the ignition\/gas circuit if it senses an over-temperature or flame-rollout condition, shutting the furnace down to protect the heat exchanger and household. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it must be reset by hand after the fault is cleared — a deliberate safety feature that flags a recurring problem instead of masking it.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM part number: 10123539\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMES920803BNAA gas furnace\u003c\/li\u003e\n\u003cli\u003eEquipment: Furnace burner \/ heat exchanger safety circuit\u003c\/li\u003e\n\u003cli\u003eCondition: New OEM (verify exact trip temperature against your original)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are safety-critical, and trip temperature and mounting must match exactly.
