Unlike an auto-reset limit, a manual-reset switch latches open when it trips and must be physically reset with its button — by design, so a serious overheat or flame-rollout event gets a technician's attention rather than silently cycling. It protects the heat exchanger and burner area from damage caused by overheating, restricted airflow, or flames rolling out of the burner box.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123517\u003c\/li\u003e\n\u003cli\u003eType: Manual-reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button (latching)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman ACSS920402BNAA (verify against your unit)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ flame-rollout protection cutoff\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana compatible\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis switch is calibrated to a specific trip temperature and uses a particular bracket and terminal layout. The OEM 10123517 ensures the correct setpoint and a proper mechanical fit. Substituting a generic switch risks the wrong trip point on a critical safety device.

About 20 minutes. Critical: if this switch tripped, diagnose and fix the underlying cause — flame rollout, blocked heat exchanger, or airflow restriction — before returning the furnace to service.
