Gas Furnace Pilot Light
 

Hello:

I have an old natural gas furnace and the pilot light keeps going out. I changed out the thermo coupler and it seemed to do well for a couple of weeks, however, the pilot light just blew out again.

Any ideas would be appreciated. Thanks, Curtis

You may need try another thermocouple but how is the heat exchangers. If the heat exchangers get plug up it make the burner kind of roll out and knocking out the pilot. You clean the pilot too?
