This 5/8-inch manual reset flame rollout switch is a critical safety component designed for gas-fired furnaces and heating systems. Its primary function is to monitor the heat levels near the burner assembly; if it detects a flame rollout condition—where flames escape the combustion chamber—the switch trips and interrupts the electrical circuit to shut down the appliance. This prevents potential fire hazards and equipment damage. This specific model is rated at L150F, meaning it is calibrated to open at 150 degrees Fahrenheit. The manual reset feature ensures that the heating system cannot restart until a technician or user has inspected the unit and manually depressed the reset button, providing an essential layer of diagnostic safety for HVAC maintenance and repair.
