Why Does My Propane Fireplace Keep Shutting Off? 

Whenever you turn your fireplace on to start burning the flames, you may notice that the flames are not going as brightly as they once did. This can be a sign of a problem with the pilot light. If the pilot light is dirty or not working properly, you may need to clean it to make it work properly again.

If you are unsure of the cause of the problem, you may want to have a professional repair it for you. A professional technician will have more experience with the intricate problems that may be encountered with your fireplace. The technician can inspect your entire unit and test the thermocouple, which is one of the main components of your gas fireplace. 

One of the first things to check if you have a pilot light problem is to check your gas supply. Your gas fireplace may be shutting off because it does not have enough gas flowing to the pilot light. If your gas supply is not on, you can turn the knob on the gas valve to the “on” position to ensure that the gas is flowing to the pilot light. If your gas valve is on, but you are experiencing problems with the pilot light, you may need to bleed the air line or replace the pilot light. 

You may also be experiencing problems with your fireplace if you smell gas coming from your fireplace. This can be a sign that there is a leak in the gas supply. It is important to open the windows and doors to allow the gas to escape. If you are not sure about the location of the leak, you should contact the utility company. They will help you determine the cause of the problem and may be able to replace the pilot light. 

Another common reason that your fireplace may not be working properly is that the thermocouple or oxy pilot is not working properly. This is a sensor that is mounted in front of the pilot flame. If the sensor is not working correctly, the flame will not be able to ignite and your fireplace will shut off. 

Using a multimeter, check to see if the thermopile output is above 300 millivolts. If the thermopile does not work properly, it may be worn or damaged. The thermopile is usually located in the main gas control valve. If the thermostat is also not working correctly, it may also be a problem. If the thermostat is working correctly, you may be able to fix the problem yourself. 

If the thermopile is damaged, you can replace it. Before replacing the thermopile, you should clean the sensor and make sure that it is properly positioned. 

Thermocouples should be replaced by a professional. Several common causes for this problem include faulty wiring and a faulty ignition fuse. You may also want to test the wiring in your fireplace and the gas service pressure. Taking additional measures may not be safe.
