I have Teledyne Lars Gas Furnace... JVT. The pilot is lit, however the burners aren't firing up. The power venter is on when I call for heat through the thermostats inside the house... I can also hear the forced hot water (actually cold since no burners) moving through the baseboards. I originally thought that my transformer was bad... for it looked old, a bit charred, etc so ordered a new and replaced it thinking that would do the trick. NOPE. Any thoughts?
