Ok heres the details.
Coleman model # 7975C856
I have noticed the that it had been kicking the fan on for a second or 2.Maybe do this one or two times before the burner would kick on.The fan would then come on normally after the burner had warmed up the heat exchanger.The last couple of days it has tripped the upper limit ,and i had to reset it.
Tonight the upper limit was not tripped,but the burner will not come on.I have a strong pilot. the T-stat is calling for heat.I pulled the cover off the furnace and was checking things.I seem to be only getting approximatly 16v. coming from the transformer on the secondary side.According to the print on the furnace i belive it calls for 24v.
From what i have read online usually a transformer either works or it don't.Is it possible mine is just putting out to little voltage to allow the burner to come on?

I need to know were to go next with my trouble shooting if this is not the problem.
