Gas Fireplace Shuts Off After 20 Minutes

So guessing it s not a heat sensor.

Gas fireplace shuts off after 20 minutes.

Always worked fine for the 8 years we ve been here. Heat n glo fireplace fire goes out after a while after 20 min or sometimes up to 1 hour but pilot stays on. Any air in the line should be looooong gone. Today i turn it on and after a few minutes the fireplace went out all by itself.

If any one component fails then the gas flow will shut off until that failure is rectified. It shuts down after 20 30 minutes of operation pilot goes off we moved into a new place and we started the fireplace today. Problem started after gas to the house had been turned off for the day. This action will start the gas flow into the fireplace logs.

After that you should turn the key a half turn. It turns on fine but after perhaps 10 minutes sometime 30 minutes the length of time varies the unit simply goes off. Gas fireplace shuts off after a few minutes. To make sure the key is in the right position you can jingle it a little until the lock slid into its place in the keyhole.

15 20 minutes and other times an hour or two. After doing some research however i now have basic knowledge about gas fires and have successfully fixed my gas fire. The latter kept going out after about half an hour even when the dial showed it as on. After it goes out and i attempt to relight it the burners will only stay lit for about 5 mins.

The fireplace does not have an automatic tempature shut off. I reach in to th. Often it s not even fully warmed up eg. It seemed to work a few times but now it will last for maybe 20 minutes and shut off.

The pilot gets great contact with the thermocouple when the fireplace is off and its just the pilot lit but when i turn on the fireplace the pilot light gets a little smaller still a strong blue and does. Though i don t worry too much about carbon monoxide poisoning i figured there must be some safety device to shut off the gas valve. That was a month ago. It should say on until i manually turn it off i found that when i first light it the burners stay lit for maybe 15 20 mins.

You need to remember to turn it counterclockwise. The pilot lamp was blue. I have a heatilator dls 18 gas fireplace installed in 1993.
