Gas logs cut off after 15 minutes

Hi. I recently started having a problem with the gas logs in my house. After about 15 minutes, they will shut off. I can go over and relight the pilot light, and they will burn for another 10-15 minutes before shutting off.



I thought at first it was due to the blower, but they do it without the blower running.



They logs are about four years old, and have worked fine up to this point. All other appliances on the natural gas line (heat, water heater and gas grill) are working fine.



Any suggestions on what to check ?



Thanx.....don

Check the ODS sensor on the pilot.

Hi, Bad thermocouple? Or loose connection to main valve? Or bad switch, or bad interlock switch for the glass front. Tony

Vented or non-vented? The problems are different.

My ventless does that every couple of years. The first time I bought a new thermocouple. [about $25] The last 2-3 times I've just taken my can of compressed air from my computer desk & blasted the whole area of the pilot [after the pilot is out, of course].

I'm not certain what gets dusty there, but I can vouch for the effectiveness of dislodging that dust.

It is a non-vented setup.

Thanks for the suggestions that have been posted.

Either the ODS is dirty or it has gone bad. The ODS is where the pilot flame comes out. Take a can of compressed air like what is used to clean computers and blow out the ODS. Blow it first from the two small holes in the sides toward the back. Then back down where the pilot flame comes out.
