Gas fireplace goes out after an hour. I have a majestic direct vent gas fireplace. Always worked fine for the 8 years weve been here. The latter keeps going out after about half an hour even when the dial shows it as on.
Heat n glo fireplace fire goes out after a while after 20 min or sometimes up to 1 hour but pilot stays 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 doesnt continue to flow and fill the room. Pilot went out gas was cut off.
However after a minute or so the whole thing shuts down. We have a natural gas fireplace with an aga gas cutoff valve inbeded in the brick hearth. There is a thermal shutoff near the pilot light.
Problem started after gas to the house had been turned off for the day. And sometimes it gets covered in soot. Gas fireplace shuts itself off.
I let the fan run and cooled the fireplace down lit the pilot no problem and turned it back on. It turns on fine but after perhaps 10 minutes sometime 30 minutes the length of time varies the unit simply goes off. We have a gas fireplace in our living room.
Today i turn it on and after a few minutes the fireplace went out all by itself. This sometimes goes bad. The thermal shutoff is there to stop the gas if the pilot light goes out.
I reach in to th. I have a heatilator dls 18 gas fireplace installed in 1993. I changed the thermocouple and the fire still goes out after about an hour with logs in place and about two hours if the logs are not in place.
