Mounted near the burner box, the rollout switch instantly cuts power to the gas valve if flames roll out of the burner compartment — a sign of a blocked heat exchanger or restricted venting.

Generic limit switches may carry a different trip temperature or reset style, causing nuisance lockouts or, worse, failing to trip when needed.
