Last updated September 7, 2023

A pilot light is a small blue flame that ignites a gas appliance. Most modern gas appliances have electric starters or igniters. In some older natural gas appliances the pilot light can go out due to drafts, condensation or mechanical failures. If you have an older appliance, you should know how to relight a pilot light. This guide reviews how to light a pilot light on a furnace, on water heaters, on stoves and in ovens.

Safety Tip: If you smell gas or hear a hissing sound around an appliance, you may have a gas leak. Do not try relighting your pilot light. Do not use your phone. Immediately leave the house.
Once outside, call a professional service technician.
