If your furnace isn’t working, the issue might be as simple as a furnace pilot light that’s gone out. Knowing how to locate and relight the pilot light can save you time and the cost of a service call. In this guide, we’ll walk you through where to find the pilot light on your furnace and the steps to safely relight it so you can get your heating back up and running in no time.
Key Takeaways
- The pilot light assembly is typically located at the bottom of the furnace, often behind a small access panel, and its presence is crucial for furnace operation.
- Key components of the pilot light system include the control knob, reset button, and thermocouple, all of which play essential roles in regulating the gas supply and ensuring the pilot light remains lit.
- Homeowners should consult a professional technician for frequent pilot light outages, unusual odors, or if safety issues arise, as these may indicate underlying problems with the furnace.
- Maintaining the pilot light is important to prevent the release of carbon monoxide, a dangerous gas that can result from inefficient burning.
Understanding Pilot Lights
A pilot light is a small, constantly burning flame that serves as the ignition source for a gas furnace. Typically located at the bottom of the furnace, near the front, and behind a small access panel, the pilot light is crucial for the furnace’s operation. This small flame ignites the burners when the furnace is turned on, allowing the system to produce heat. Without a functioning pilot light, your gas furnace will not be able to generate the warmth needed to keep your home comfortable.
Locating the Pilot Light Assembly
Locating the furnace's pilot light assembly is a key step in addressing furnace issues. However, as the exact location can vary by furnace type, it’s best to consult a professional technician. They can quickly identify whether your furnace uses a pilot light or an electric igniter and address any issues efficiently, saving you time and frustration. For safe and reliable solutions, leave the troubleshooting to the experts.
Identifying Your Furnace Type
Your furnace type determines if it uses a pilot light or an electronic ignition system. Older models typically ignite natural gas through a pilot light, while newer ones use an electronic igniter. The pilot light is essential for furnace operation; without it, the furnace won’t function.
If you’re unsure whether your furnace has a pilot light or an electronic igniter, contact a professional HVAC technician. They can assess your furnace type, ensure it’s functioning properly, and handle any troubleshooting or repairs needed. Leave it to the experts for safe and efficient service.
Common Locations for Pilot Lights
Pilot lights, often seen as a small blue flame, are typically located at the bottom of the furnace near the control knob or front. In older gas furnaces, they are usually behind a small access panel at the bottom front.
If you’re unsure where to find the pilot light or how to handle it, contact a professional technician for assistance. They can safely locate and address any issues with your furnace.
Understanding the Pilot Light Components
Understanding the components of your gas furnace’s pilot light assembly, such as the control knob, reset button, and thermocouple, is helpful for recognizing potential heating issues.
The control knob regulates gas flow for steady ignition, while the thermocouple acts as a safety feature by detecting the pilot light flame. Dirt accumulation in the pilot light area can lead to issues like a weak or extinguished flame, impacting furnace performance. For any troubleshooting or maintenance, it’s best to contact a professional technician to ensure the safe and efficient operation of your furnace.
When to Call a Professional Technician
Should the pilot light extinguish repeatedly despite efforts to relight it, it’s imperative to engage experts. For recurrent extinguishments, peculiar odors, or when you detect a scent of gas, professional assistance is essential. Homeowners must enlist the services of a qualified HVAC firm for ongoing equipment complications.
If lighting the pilot light on your own proves challenging, make sure to reach out to an expert HVAC technician immediately. Safety should always be given top priority.
Signs You Need Professional Help
Frequent furnace pilot light outages indicate the need for professional help from a furnace technician, as they may signal underlying issues requiring expert diagnosis. Strange odors from the furnace area necessitate immediate furnace repair evaluation.
A working thermocouple prevents gas leaks and ensures safety. Seek professional help if you notice any warning signs.

Frequently Asked Questions
How do I know if my furnace has a pilot light or an electronic ignition?
If your furnace has a small, steady flame visible within, this indicates that it is equipped with a pilot light.
On the other hand, in the absence of such a flame and when an electrical current is used to ignite the gas, then your system employs an electronic ignition.
Where is the pilot light assembly typically located in my furnace?
The pilot light assembly is typically located at the bottom of the furnace, near the control knob, or the front of the unit. This placement makes it accessible for maintenance and ignition purposes.
What should I do if my pilot light keeps going out?
If your pilot light keeps going out, it’s crucial to address potential issues such as drafts, dirt buildup, or a malfunctioning thermocouple.
Consulting a professional HVAC technician will help ensure a thorough inspection and proper resolution of the problem.
How long should I wait before relighting the pilot light after turning off the gas supply?
You should wait at least 5 minutes before relighting the pilot light to ensure any residual gas has safely dissipated, minimizing the risk of fire.
