- Thermocouple issues: A faulty or malfunctioning thermocouple can shut off the gas supply to the pilot light, causing it to go out.
- Moisture or drafts: Moisture or drafts can extinguish the pilot light flame or cause it to flicker.
Troubleshooting Steps
To troubleshoot the issue, follow these steps:
- Check the pilot light orifice: Use a small brush or toothbrush to clean out any debris or dirt from the pilot light orifice.
- Inspect the connections: Check the connections between the pilot light electrode, thermocouple, and gas valve for any signs of corrosion or looseness. Tighten any loose connections and replace any corroded parts.
- Check the gas pressure: Ensure that the gas pressure is within the recommended range. Consult your owner’s manual or contact a professional if you’re unsure.
- Test the thermocouple: Use a multimeter to test the thermocouple for any signs of malfunction. Replace the thermocouple if necessary.
- Check for moisture or drafts: Ensure that the area around the fireplace is dry and free from drafts.
Additional Solutions
If the troubleshooting steps above don’t resolve the issue, consider the following additional solutions:
- Replace the pilot light electrode: A worn-out or damaged pilot light electrode can cause the pilot light to go out. Replace the electrode with a new one.
- Adjust the pilot light flame: If the pilot light flame is too small or too large, it can cause the flame to go out. Adjust the flame size by turning the adjustment screw.
- Check the gas valve: Ensure that the gas valve is fully open and not restricted. Clean or replace the gas valve if necessary.
Preventative Maintenance
To prevent pilot light issues in the future, consider the following preventative maintenance tips:
- Annual cleaning: Clean the pilot light orifice, electrode, and thermocouple annually to ensure optimal performance.
- Regular inspections: Regularly inspect the connections, gas valve, and thermocouple for any signs of wear or damage.
- Proper storage: Store the fireplace and its components in a dry, protected area during the off-season.

What are the common causes of a pilot light not staying lit on a gas fireplace?
A pilot light not staying lit on a gas fireplace can be caused by several factors. Some of the most common causes include a faulty thermocouple, a dirty or clogged pilot light orifice, or a malfunctioning pilot light assembly. Additionally, issues with the gas supply line, such as a leak or blockage, can also prevent the pilot light from staying lit.
It’s also possible that the pilot light is not receiving enough oxygen to stay lit, which can be caused by a lack of airflow or a blocked vent. In some cases, the pilot light may not be adjusted correctly, which can also cause it to go out. Identifying the root cause of the problem is crucial to resolving the issue and getting the pilot light to stay lit.
How do I troubleshoot a pilot light that won’t stay lit on my gas fireplace?
To troubleshoot a pilot light that won’t stay lit on your gas fireplace, start by checking the gas supply line for any leaks or blockages. Make sure that the valve is fully open and that there are no kinks or restrictions in the line. Next, inspect the pilot light orifice and assembly for any signs of dirt or debris. Clean out any blockages and make sure that the orifice is clear.
If the issue persists, try adjusting the pilot light to see if it makes a difference. You may also want to check the thermocouple to ensure that it is functioning correctly. If none of these steps resolve the issue, it may be necessary to call a professional to diagnose and repair the problem.
What is a thermocouple and how does it relate to my pilot light?
A thermocouple is a safety device that is designed to shut off the gas supply to the pilot light if it detects that the flame has gone out. It works by generating a small electrical current when the pilot light is lit, which keeps the gas valve open. If the pilot light goes out, the thermocouple cools down and the electrical current stops, causing the gas valve to shut off.
If the thermocouple is faulty, it may not be able to detect the pilot light flame correctly, which can cause the gas valve to shut off and the pilot light to go out. In this case, replacing the thermocouple may be necessary to resolve the issue.
Can I replace the pilot light assembly myself or do I need a professional?
Replacing the pilot light assembly can be a relatively straightforward process, but it does require some technical knowledge and expertise. If you are comfortable with DIY repairs and have experience working with gas appliances, you may be able to replace the pilot light assembly yourself. However, if you are not confident in your abilities or if you are unsure about any aspect of the process, it’s recommended to call a professional.
