Mounted on the burner assembly or manifold bracket, this normally-closed safety device opens the ignition circuit if flame rolls out of the heat exchanger, protecting the cabinet, wiring, and homeowner from an unsafe combustion condition.\u003c\/p\u003e\u003cp\u003eA tripped or failed rollout switch typically shows up as a furnace that locks out on a hard fault and will not attempt ignition until the cause is corrected and the switch is reset.
