How to Light Pilot Light on Gas Furnace: A Step-by-Step Guide
What is a Pilot Light?
A pilot light is a small flame that ignites the main burner in a gas furnace. It is typically located at the bottom of the furnace and is used to light the gas burners. The pilot light is usually a small, continuous flame that is used to ignite the main burners when the furnace is turned on.
Why is the Pilot Light Important?
The pilot light is an essential component of a gas furnace. Without a functioning pilot light, the furnace will not be able to produce heat. If the pilot light is not lit, the furnace will not be able to ignite the main burners, and the system will not be able to provide heat to the home.
