What causes furnace flame rollout?

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 is a rollout limit switch?

Rollout switches are typically going to be a manual reset switch with a higher temperature rating than the other limits within the unit.
