______________________________________________________________________ We have a Tempstar DC90, Model NUGM075EGA1 Gas furnace on which our pilot seems to be going out. I reset and re-start the furnace and all seems to work well again temporarily. Last time I restarted, it ran with no problems for 2 weeks before the flame died. Not knowing the first thing about HVAC, I do not know what additional information to put here. Toss me some questions so I could obtain the best help I can get. Thanks for your time and patience!

If this did not fix the problem , then you should call a professional to check out system for your safety..
