Why is Pilot Light Going Out?
The pilot light is an essential component of many home appliances, including furnaces, water heaters, and gas stoves. Its primary function is to provide a small, continuous flame that ignites the main burner when needed. However, pilot lights can and do go out from time to time, leaving homeowners wondering why this happens. In this article, we will explore the common reasons why pilot lights go out and provide tips on how to prevent and troubleshoot these issues.
Why Does the Pilot Light Go Out?
There are several reasons why a pilot light may go out. Some of the most common causes include:
- Blockages: Blockages in the pilot light tube or venting system can prevent the pilot light from getting the oxygen it needs to stay lit. Hairpin-shaped bends in the tube can also cause the pilot light to go out.
- Dirty or corroded pilot light electrodes: Corrosion or buildup on the electrodes can prevent the pilot light from igniting properly.
- Incorrect pilot light assembly: Improper installation or assembly of the pilot light can cause it to malfunction.
- Gas supply issues: Problems with the gas supply line, such as leaks or blockages, can prevent the pilot light from getting the fuel it needs.
- Pilot light adjustment issues: Improper adjustment of the pilot light can cause it to go out.
Common Pilot Light Issues
Here are some common pilot light issues that homeowners may encounter:
- Pilot light won’t stay lit: The pilot light may not stay lit due to blockages, dirty or corroded electrodes, or incorrect pilot light assembly.
- Pilot light keeps going out: The pilot light may keep going out due to gas supply issues, pilot light adjustment issues, or a faulty thermocouple.
- Pilot light won’t light: The pilot light may not light at all due to a faulty pilot light or a problem with the ignition system.
How to Troubleshoot Pilot Light Issues
If your pilot light is not functioning properly, here are some steps you can take to troubleshoot the issue:
- Check the pilot light tube: Make sure the pilot light tube is clear of blockages and debris.
- Clean the electrodes: Clean the electrodes to remove any corrosion or buildup.
- Check the gas supply: Check the gas supply line for any leaks or blockages.
- Adjust the pilot light: Adjust the pilot light to ensure it is properly aligned and adjusted.
- Replace the thermocouple: If the pilot light keeps going out, the thermocouple may be faulty and needs to be replaced.
Preventing Pilot Light Issues
Here are some steps you can take to prevent pilot light issues:
- Regularly clean the pilot light tube: Regularly cleaning the pilot light tube can help prevent blockages and ensure the pilot light stays lit.
- Check the gas supply: Regularly check the gas supply line for any leaks or blockages.
- Adjust the pilot light: Regularly adjust the pilot light to ensure it is properly aligned and adjusted.
- Use a pilot light cover: Using a pilot light cover can help protect the pilot light from debris and moisture.
- Schedule regular maintenance: Schedule regular maintenance with a licensed HVAC technician to ensure your pilot light system is functioning properly.
