Why Would the Pilot Light Go Out?
The pilot light is a crucial component of many appliances, including furnaces, water heaters, and boilers. Its primary function is to ignite the main burner, which provides heat to the system. However, pilot lights can and do go out, leaving homeowners without heat or hot water. In this article, we will explore the reasons why pilot lights go out and provide solutions to prevent and fix the issue.
What Causes Pilot Lights to Go Out?
There are several reasons why a pilot light may go out. Some of the most common causes include:
• Incorrect Lighting: Proper lighting technique is crucial to ensure the pilot light stays lit. Make sure to light the pilot correctly, and do not touch the pilot or burner after lighting.
• Air Pressure: Air pressure changes can cause the pilot light to go out. This is more common in areas with high winds, storms, or altitude changes.
• Gas Leaks: Gas leaks can cause the pilot light to go out or fail to stay lit. If you suspect a gas leak, turn off the gas supply and contact a professional.
• Faulty Thermocouple: The thermocouple is a critical component that ensures the pilot light stays lit. If it becomes faulty, the pilot light may go out.
• Dirty or Clogged Burner: Dirty or clogged burners can prevent the pilot light from staying lit.
• Worn-Out Igniter: The igniter is responsible for igniting the pilot light. If it becomes worn out, the pilot light may go out.
How to Prevent Pilot Lights from Going Out
To prevent pilot lights from going out, follow these tips:
• Regular Maintenance: Regular maintenance is crucial to ensure the pilot light stays lit. Check and clean the burner, thermocouple, and igniter regularly.
• Proper Installation: Ensure the pilot light is installed correctly and follows the manufacturer’s instructions.
• Monitor Air Pressure: Monitor air pressure changes and adjust the pilot light accordingly.
• Inspect for Gas Leaks: Regularly inspect for gas leaks and address any issues promptly.
• Replace Worn-Out Parts: Replace worn-out parts, such as the igniter, to prevent pilot light failures.
What to Do if the Pilot Light Goes Out
If the pilot light goes out, follow these steps:
• Turn Off the Gas Supply: Turn off the gas supply to the appliance to prevent any accidents or damage.
• Wait for Cooling: Wait for the appliance to cool down before attempting to relight the pilot.
• Check the Thermocouple: Check the thermocouple to ensure it is not faulty or damaged.
• Relight the Pilot: Follow the manufacturer’s instructions to relight the pilot. Make sure to light the pilot correctly and do not touch the pilot or burner after lighting.
• Check for Obstructions: Check for any obstructions, such as dirty or clogged burners, that may be preventing the pilot light from staying lit.
Troubleshooting Common Pilot Light Issues
Here are some common pilot light issues and their solutions:
| Issue | Solution |
|---|---|
| Pilot light will not stay lit | Check for air pressure changes, ensure proper lighting technique, and inspect for gas leaks. |
| Pilot light keeps going out | Check the thermocouple, ensure proper installation, and replace worn-out parts. |
| Pilot light will not light | Check the igniter, ensure proper installation, and inspect for gas leaks. |
Conclusion
Pilot lights are a crucial component of many appliances, and their failure can leave homeowners without heat or hot water. By understanding the common causes of pilot light failures and following the tips provided in this article, homeowners can prevent and fix pilot light issues. Remember to regularly maintain your appliances, monitor air pressure changes, and inspect for gas leaks to ensure your pilot lights stay lit and your appliances function properly.
