Question 1

what is flame rollout

Accepted Answer

A furnace flame rollout is a dangerous situation that can occur when the flame from a furnace burner extends outside of the burner area and into the surrounding area of the furnace. This can lead to fires or explosions if the flame comes into contact with flammable materials or gases. The flame rollout is often caused by a malfunctioning furnace, such as a blocked or dirty burner or a faulty gas valve. It is important to have your furnace regularly inspected and maintained to prevent flame rollout and ensure safe operation.

Question 2

flame roll out switch keeps tripping

Accepted Answer

If your furnace's flame rollout switch keeps tripping, it could be an indication of a serious problem with your furnace. The flame rollout switch is a safety mechanism that is designed to shut off the furnace if it detects that the flame is rolling out of the combustion chamber, which can be caused by various factors such as blockage, clogged burners or heat exchanger, or a malfunctioning gas valve.

If the switch keeps tripping, it could mean that there is a persistent issue with the furnace that needs to be addressed. It is essential to have a professional HVAC technician inspect and repair your furnace as soon as possible to prevent any potential safety hazards. Ignoring a tripped flame rollout switch can lead to further damage to your furnace or even cause a fire or explosion.
