How to Relight a Pilot Light: A Step-by-Step Guide
The pilot light is a small flame that ignites the main burner of your gas water heater, furnace, or boiler. If your pilot light goes out, it can be frustrating and even cause discomfort during cold winter months or when you need hot water. Fortunately, relighting a pilot light is a relatively simple process that you can do yourself with a few basic tools. In this article, we will walk you through the steps to relight a pilot light and provide some troubleshooting tips to help you identify and fix common issues.
Why Is My Pilot Light Out?
Before we dive into the relighting process, it’s essential to understand why your pilot light may have gone out in the first place. Common reasons for a pilot light to go out include:
• Dirty or clogged burner: Debris, corrosion, or sediment buildup in the burner or pilot assembly can prevent the pilot light from igniting.
• Incorrectly adjusted burner: If the burner is not adjusted properly, it can cause the pilot light to extinguish.
• Carbon monoxide buildup: Carbon monoxide buildup in the flue can cause the pilot light to go out.
• Power outage: A sudden power outage can cause the pilot light to go out.
• Worn-out thermocouple: The thermocouple is responsible for sensing the pilot light and shutting off the gas supply when it’s not present. A worn-out thermocouple can prevent the pilot light from igniting.
How to Relight a Pilot Light
Relighting a pilot light is a straightforward process that requires a few basic tools and some caution. Follow these steps:
- Turn off the gas supply: Before attempting to relight the pilot light, turn off the gas supply to the appliance at the shut-off valve. This is an important safety precaution to prevent accidental ignition and potential explosion.
- Let the appliance cool down: Allow the appliance to cool down completely before attempting to relight the pilot light. This will prevent burns and ensure your safety.
- Remove the pilot light cover: Remove the pilot light cover by unscrewing it or sliding it off. Be careful not to touch any of the internal components or electrical wiring.
- Light the pilot light: Hold a lit match or lighter to the pilot light opening, and gently press the igniter button (usually located on the side of the pilot light) while holding the flame to the opening. Make sure to keep the flame steady and at the correct angle to ensure proper ignition.
- Hold the pilot light for a few seconds: Hold the pilot light for 5-10 seconds to allow it to stabilize and adjust to the correct flame height.
- Adjust the pilot light: Once the pilot light is relit, adjust the flame height by turning the adjusting screw or knob. Make sure the flame is burning steadily and at the correct height.
- Turn on the gas supply: Once the pilot light is relit and adjusted, turn on the gas supply at the shut-off valve.
Troubleshooting Tips
If you’ve followed the steps above and still can’t relight your pilot light, there may be a more complex issue at play. Here are some common troubleshooting tips:
• Check the thermocouple: If the thermocouple is worn out or damaged, it may prevent the pilot light from igniting. Check the thermocouple and replace it if necessary.
• Clean the burner: A dirty or clogged burner can prevent the pilot light from igniting. Use a soft-bristled brush or cloth to clean the burner and pilot assembly.
• Check for carbon monoxide buildup: If you suspect carbon monoxide buildup, have the appliance inspected by a professional to ensure safe operation.
• Replace the pilot light assembly: If none of the above steps resolve the issue, it may be necessary to replace the pilot light assembly.
Safety Precautions
When working with gas appliances, it’s essential to follow proper safety precautions to prevent accidents and ensure safe operation. Remember to:
• Turn off the gas supply: Always turn off the gas supply at the shut-off valve before attempting to relight the pilot light or perform any maintenance.
• Avoid touching electrical wiring: Keep away from any electrical wiring or components to prevent electrical shock.
• Wear protective gear: Wear protective gear, such as gloves and safety glasses, when working with gas appliances.
• Have the appliance inspected: If you’re unsure about the cause of the pilot light going out or if you’re not comfortable with the relighting process, have the appliance inspected by a professional.
Conclusion
Relighting a pilot light is a relatively simple process that requires some basic tools and caution. By following the steps outlined in this article and taking the necessary safety precautions, you should be able to relight your pilot light and get your gas appliance up and running again. Remember to troubleshoot common issues and have the appliance inspected by a professional if necessary. With these tips and guidelines, you’ll be well on your way to keeping your gas appliance running smoothly and safely.
