I have a GMP gas furnace, the ignitor lights, the burners light for about 15 secs. Then go out and try to re-light after about 30 secs. Ocassionly staying lit it's a 50-50 chance here. What do I need to do to correct this problem?


Thanks for the help.

Look for the blink code on the circuit board.

It's a good chance you just have a dirty flame sensor. It's a small metal rod in front of the burners with one wire going to it. Turn the power off to the furnace and scrape it with a knife to get it clean. Restore power and give it a try.
