I have a Miller furnace that the blower motor is running constant and no heat.I have checked the High temp sensor and it shows good,The switch that reads vaccuum seems to be working with blower running the contacts are closed.The transformer is good putting 24/26 volts to the board but no voltage on the "R" terminal going to the T-Stat.Is there any fuse that is soldered on the board Robertshaw 100-82706 ?
I started smelling something about a week ago and could not figure where it was comming from till this morning when I lost heat I found a Blown CAP and replaced it,But with it being shorted I think it took something else I'm hoping it is a fuse.
I would have it looked at if I could afford it and the 2 small heaters I have dont do enough.

Thanks for the help.

Scott
