Flame rollouts in gas furnaces and boilers are caused by a high concentration of combustion gases inside the combustion chamber. Normally, these inflammable gases are exhausted from the furnace through the flue passageways in the heat exchanger, then up the vent to the exterior of the home.

What activates a flame rollout switch?
There are several things that can cause flame rollout and the flame rollout switch to trip. They all have something to do with the interruption of a smooth draft passing over the flames, through the heat exchanger and out the flue. Here are some of them: Buildup of soot.

Can you bypass a rollout switch?
Can I bypass the flame rollout switch on my furnace? Yes, you can. But it is a bad idea – even for a “little while” until you can get a new one installed.

What causes flame to go out on furnace?
Your furnace has a limit switch that keeps it from running if the heat exchanger is too hot. Dirty filters, closed or blocked vents and other blockages in airflow are common causes of an overheated furnace. A bad limit switch. The limit switch may be bad and need to be replaced.
What causes a rollout switch to open?
Rollout switches trip because flames are burning back where they are not supposed to be. Possible causes include a stopped up vent, a stopped up heat exchanger, low gas pressure, or a cracked heat exchanger. All of these conditions are very serious and have the potential to do great harm.

Why is my flame rollout switch tripping?
Rollout switches trip because flames are burning back where they are not supposed to be. Possible causes include a stopped up vent, a stopped up heat exchanger, low gas pressure, or a cracked heat exchanger. All of these conditions are very serious and have the potential to do great harm.
What causes water heater flame rollout?
Rollout is caused by the combination of gases and flames present when the furnace is in operation. When the furnace is on, flames ignite and are meant to remain inside the combustion chamber. In some cases, gases which are not flammable will build inside the chamber, which prevents oxygen from getting to the flames.

Can a gas valve cause flame rollout?
When flame rollout occurs, boiler components outside the combustion chamber that are not fire-resistant may be compromised by exposure to the flame. Principally, these include the boiler gas valve and electrical wiring leading to the valve, as well as any other components or parts with a low melting point.
