This high-limit \/ rollout switch opens the circuit to the gas valve when it senses excessive temperature — a symptom of flame rollout, a blocked flue, or a failed blower. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it must be pressed to re-close after a trip, ensuring the furnace does not silently cycle on a genuine safety fault.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eFunction: normally-closed thermal safety cutoff to gas valve\u003c\/li\u003e\n\u003cli\u003eReset: manual push-button\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMH81405DXCB furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10123529\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature matched to the heat exchanger.
