Mounted as a secondary overheat\/rollout safeguard, this bi-metal snap-disc opens the control circuit if it detects excessive temperature — for example from flame rollout or a blocked flue — and automatically closes again once conditions return to normal.

Generic replacements may carry a different calibration or terminal layout, compromising protection or fit.
