I would check the flue out side first to make sure it is not blocked. If flue looks good i would try cleaning or replace thermalcoupl. Most of the dyna glo heater i have worked on have a thermal pile instead of thermalcoupl. If you have a thermal pile then i would lite pilot and hold knob down for about 3-5 minutes before you turn gas valve knob to on. If that doesnt work let me no and i can give you somemore ideas. I hope you get it working. What is the tempature out side?
