Heating
Pilot Light
A small, continuously burning flame in older gas furnaces and water heaters that ignites the main burner when the thermostat calls for heat.
What Is a Pilot Light?
A pilot light is found in older gas-fired heating equipment. It's a small flame that stays lit continuously, ready to ignite the main burner when your thermostat calls for heat. Modern furnaces have replaced standing pilot lights with electronic ignition systems (hot surface igniters or spark ignitors) that are more efficient and reliable. If you have an older system with a pilot light that keeps going out, it could indicate a faulty thermocouple, drafts, or other issues.
Why It Matters for Your Home
A pilot light that frequently goes out isn't just an inconvenience — it can signal a deeper problem with your heating system. While relighting a pilot is straightforward, recurring issues need professional diagnosis. If you smell gas when the pilot is out, leave the house and call your gas company immediately.
