I have a Janitrol furnace model GMP125-4. After I fixed my blinking circuit board problem which said my pressure switch was stuck open, so I sucked on it, retested everything and finally thought I had fixed it myself. But now I found out it's not the pressure switch and the ignitor works fine, but only the first 3 burners light. The last two do not light therefore flames never reach the flame sensor. I have managed to put a pipe cleaner through the two that aren't working and there seems to be nothing clogging them. Can anyone help with what I should I should do next. I can't afford to call the proper person to fix this, so I am trying to do it myself. Please HELP!!!!

the burner manifold has a 'crossover', a groove or channel to allow the flame to move from the igniter to the last burner.
Check to make sure this is clean.

Thanks for such a fast reply. But upon looking at how I would have to take the manifold off, I decided that I am just not comfortable doing that. I am afraid of the potential gas leaks when I would put it back together. But thanks again for your help!!!
