Why Pilot Light Keeps Going 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. The pilot light is designed to remain lit continuously, providing a steady source of energy to the appliance. However, many homeowners have experienced the frustration of a pilot light that keeps going out. In this article, we will explore the common reasons why a pilot light keeps going out and provide some tips on how to troubleshoot and fix the issue.
Common Reasons Why Pilot Light Keeps Going Out
Before we dive into the solutions, it’s essential to understand the common reasons why a pilot light keeps going out. Here are some of the most common causes:
- Dirty or clogged pilot light orifice: The pilot light orifice is the small opening where the pilot flame emerges. If the orifice is clogged with debris or dirty, it can prevent the pilot flame from igniting or staying lit.
- Incorrect pilot light assembly: If the pilot light assembly is not installed correctly, it can cause the pilot flame to go out.
- Low gas pressure: If the gas pressure is too low, it can prevent the pilot flame from staying lit.
- Faulty thermocouple: The thermocouple is a critical component that helps to maintain the pilot flame. If it’s faulty, it can cause the pilot flame to go out.
- Drafts or wind: If there are drafts or wind in the area, it can extinguish the pilot flame.
- Pilot light burner malfunction: If the pilot light burner is malfunctioning, it can cause the pilot flame to go out.
How to Troubleshoot a Pilot Light That Keeps Going Out
Before attempting to fix the issue, it’s essential to troubleshoot the problem to identify the root cause. Here are some steps to follow:
- Check the pilot light orifice: Use a toothbrush or a small brush to clean the pilot light orifice. Make sure to remove any debris or dirt that may be blocking the orifice.
- Check the pilot light assembly: Verify that the pilot light assembly is installed correctly. Make sure all connections are secure and there are no signs of damage.
- Check the gas pressure: Check the gas pressure in your home to ensure it’s within the recommended range. If the pressure is low, you may need to adjust the regulator or contact a professional to increase the pressure.
- Check the thermocouple: Check the thermocouple for any signs of damage or wear. If it’s faulty, you may need to replace it.
- Check for drafts or wind: Check the area around the pilot light for any drafts or wind. If you find any, you may need to adjust the appliance or seal any gaps to prevent drafts.
- Check the pilot light burner: Check the pilot light burner for any signs of malfunction. If it’s faulty, you may need to replace it.
Tips for Preventing Pilot Light Issues
To prevent pilot light issues, follow these tips:
- Regularly clean the pilot light orifice: Clean the pilot light orifice regularly to prevent debris and dirt from building up.
- Check the pilot light assembly regularly: Check the pilot light assembly regularly to ensure it’s installed correctly and there are no signs of damage.
- Maintain proper gas pressure: Ensure that the gas pressure in your home is within the recommended range.
- Replace the thermocouple regularly: Replace the thermocouple regularly to prevent it from becoming faulty.
- Seal any gaps or drafts: Seal any gaps or drafts around the appliance to prevent wind and air from extinguishing the pilot flame.
