Lost my manual and my attempts to follow the drop down instructions don't work continually.One setting will and the next just quits and the furnace doesn't go on. I just had a new circuit baord installed could it be the problem? Granny in a cold house any help appreciated.

Hello Granny. It would be best for you to have a service call done on your equipment so that you stop spending $$$ on parts that are not needed.
I also hate to see a Granny frreeze.
