Gas Fireplace Pilot Light Goes Out When Turned To On

Gas fireplaces are a popular choice for many homeowners, as they provide a cozy and inviting ambiance. However, like any other appliance, gas fireplaces can occasionally experience problems. One common issue is the pilot light going out when the fireplace is turned on. If you're experiencing this problem, don't worry – it's usually a relatively easy fix.

There are a few different reasons why the pilot light on a gas fireplace might go out when turned on. One possibility is that the thermocouple is not properly seated. The thermocouple is a small device that senses the presence of a flame and sends a signal to the gas valve to open. If the thermocouple is not properly seated, it may not be able to sense the flame and the gas valve will shut off.

Another possibility is that the gas valve is not working properly. The gas valve is responsible for controlling the flow of gas to the pilot light. If the gas valve is not working properly, it may not be able to open and allow gas to flow to the pilot light.

Finally, it is also possible that there is a blockage in the gas line. A blockage in the gas line will prevent gas from flowing to the pilot light and cause it to go out.

If you're experiencing problems with the pilot light on your gas fireplace, there are a few things you can do to troubleshoot the issue:

1. Check to make sure that the thermocouple is properly seated. The thermocouple should be located near the pilot light and should be held in place by a small clip. If the thermocouple is not properly seated, remove it and reinsert it. 2. Check to make sure that the gas valve is working properly. The gas valve is usually located near the bottom of the fireplace and is connected to the gas line. To test the gas valve, turn the knob to the "on" position and listen for a clicking sound. If you do not hear a clicking sound, the gas valve may not be working properly and will need to be replaced. 3. Check for blockages in the gas line. A blockage in the gas line will prevent gas from flowing to the pilot light and cause it to go out. To check for blockages, turn off the gas supply to the fireplace and disconnect the gas line. Then, use a flashlight to look inside the gas line and check for any debris or blockages. If you find any blockages, remove them and reconnect the gas line.

If you've tried all of the above troubleshooting steps and the pilot light is still going out when the fireplace is turned on, you may need to call a qualified gas fireplace technician to diagnose and repair the problem.
