my dad was trying to fix the furnace because its not working and won't produce heat. I looked up briefly on the net to find a solution to this and found one method'. It suggested that the thing you should check up first is the t-stat, where you open it up and connect two wires and wait a few seconds to see if the furnace starts up again. My dad tried this and nothing happened.
What could be the problem? Any suggestions and helpful things we could do would be appreciated. thanks.
I'll provide some info if need be.
