Gas fireplace shuts off after a few minutes. Gas fireplace burns then shuts down pilot light works fine when i throw on the wall switch the main burner ignites fine. It starts up fine runs for about 5 10 minutes than completely shuts offpilot and all. I have replaced the valve the thermopile and over temp sensor.
Vent free gas heater support. If the gas fireplace shuts off after a few minutes its pretty much always going to be a pilot head issue or a valve issue. Gas fireplace worked fine last winter and the winter prior.
This only occurs in the minutes after start up and does not occur when the fireplace has been running for more then ten minutes. At turn on there is significant oxygen and the fire consumes the oxygen but there is a problem the consumed gas needs to push the heavy and dense cold air in the chimney up out of the pipe in order to draw. The pilot will re light without problem and the whole sequence can be repeated ad infinitum.
Take note that its the pilot head not the thermocouple. Vent free gas heater support. Why does my gas fireplace go out after only a few minutes of running.
Now in the past two times its been used last week and tonite it will shut itself off after about 20 min. The whole assembly is usually replaced and they usually come at the same price. However after a minute or so the whole thing shuts down.
There is no room for errors when you are dealing with gas appliances. My gas stovefireplace is smoking. Today i turn it on and after a few minutes the fireplace went out all by itself.
Always worked fine for the 8 years weve been here.
