This 5/8-inch manual reset flame rollout switch is a vital safety component for gas furnaces and HVAC heating systems. Designed to monitor the temperature within the burner compartment, this thermal limit switch acts as a failsafe, automatically interrupting the electrical circuit to the gas valve if it detects a flame rollout—a dangerous condition where flames escape the combustion chamber. Featuring a fixed L270F trip point, the switch opens at 270 degrees Fahrenheit. Because it is a manual reset model, it ensures that the heating system cannot restart until a technician has inspected the unit and manually reset the device, providing an extra layer of protection against persistent venting or combustion issues. It is a common replacement part for maintaining the safe operation of residential and commercial gas-fired appliances.
