I recently purchased a home that has a gas fireplace.
Gas fireplace shuts off and comes back on.
It took quite a while.
We turned the gas lines back on and bled out all the air.
I can t believe my eyes but this fixed my fireplace too.
On the contrary if you want to.
There are multiple things that could be going on.
The thermocouple is a small device that generates electricity from heat they are used in gas furnaces and such to shut off the gas in case the pilot goes out so gas doesn t continue to flow and fill the room.
The previous owners installed the fireplace less than 1 year ago.
I have a heatilator dls 18 gas fireplace installed in 1993.
When your gas fireplace shuts off and pilot goes out usually it means that the thermocouple is bad or on the way of being bad.
It turns on fine but after perhaps 10 minutes sometime 30 minutes the length of time varies the unit simply goes off.
They turn off the gas lines during the summer so that the line runs to the pool heater.
It has been shutting itself off after a minute then turning itself back on repeatedly for over a year.
You could be dealing with a bad thermo couple thermo pile.
I called a service person and he couldn t fix it without recommending we spend 500 to replace a part.
Pilot light stayed on the whole time though.
The thermo couple is a sensor that senses heat a.
So we chose to leave it.
I admit i m no expert when it comes to gas fire places but i had an old gas heater that displayed similar issues and it turned.
The first thing you need to do it call a hearth professional and have the unit serviced.
