What to Do When Pilot Light Goes Out?
A pilot light is a small flame that ignites the main burner in a gas-fired appliance, such as a water heater, furnace, or stove. When the pilot light goes out, it can cause a range of problems, from a lack of hot water to a cold home. In this article, we’ll explore what to do when the pilot light goes out and provide step-by-step instructions for relighting it.
What Causes the Pilot Light to Go Out?
Before we dive into the solution, it’s essential to understand what causes the pilot light to go out. Here are some common reasons:
- Drafts: Strong winds or poor ventilation can extinguish the pilot light.
- Clogged or dirty pilot orifice: Debris or mineral buildup can block the pilot light from burning properly.
- Incorrect gas pressure: Low or high gas pressure can cause the pilot light to malfunction.
- Faulty thermocouple: The thermocouple is responsible for sensing the pilot light’s heat and generating a small electric current to maintain the pilot flame. A faulty thermocouple can prevent the pilot light from staying lit.
- Age and wear: Pilot lights can simply wear out over time, especially if the appliance is old or not properly maintained.
Step-by-Step Instructions for Relighting the Pilot Light
Relighting the pilot light is a relatively simple process, but it’s crucial to follow the correct steps to ensure your safety and the appliance’s proper functioning. Here’s a step-by-step guide:
- Turn off the gas supply: Locate the shut-off valve for the gas supply line and turn it clockwise to shut off the gas supply to the appliance.
- Wait for 5 minutes: Allow the gas to clear from the lines before attempting to relight the pilot.
- Check the pilot light orifice: Remove any debris or dust from the pilot light orifice using a small brush or a toothpick.
- Relight the pilot light: Hold a lit match or lighter to the pilot light orifice for about 5-10 seconds, or until the pilot light ignites. Make sure to hold the flame steady and away from your face.
- Adjust the pilot light orifice: If the pilot light is not burning steadily, adjust the orifice by turning the adjustment screw clockwise to increase the flame or counterclockwise to decrease it.
- Check the thermocouple: Ensure the thermocouple is not blocked or damaged. If it’s damaged, consider replacing it.
- Turn on the gas supply: Once the pilot light is relit, turn the shut-off valve counterclockwise to restore the gas supply to the appliance.
Troubleshooting Common Issues
If the pilot light continues to go out, it may be due to one of the following issues:
- Incorrect gas pressure: Check the gas pressure regulator to ensure it’s set correctly.
- Clogged or dirty pilot orifice: Clean or replace the orifice as needed.
- Faulty thermocouple: Consider replacing the thermocouple if it’s damaged or faulty.
- Poor ventilation: Ensure good ventilation around the appliance to prevent drafts from extinguishing the pilot light.
Preventative Maintenance
To prevent the pilot light from going out, it’s essential to perform regular maintenance on your appliances. Here are some tips:
- Clean the pilot light orifice: Clean the orifice every 6-12 months to prevent debris buildup.
- Check the thermocouple: Inspect the thermocouple regularly for signs of damage or wear.
- Maintain good ventilation: Ensure good airflow around the appliance to prevent drafts from extinguishing the pilot light.
- Replace worn-out parts: Replace worn-out parts, such as the thermocouple or pilot light orifice, as needed.
Conclusion
When the pilot light goes out, it can be frustrating and inconvenient. However, by following the step-by-step instructions outlined in this article, you can relight the pilot light and get your appliance functioning properly again. Remember to perform regular maintenance to prevent the pilot light from going out in the future.
