The Lenox is 7 yrs old gas furnance. It comes on fine.
the problem I am having is that the air blows warm
and will not get hot. The burners are OK.
It just stops blowing after about 2 mintues. A service guy came
out yesterday and said I need a mother board for
the computer. Is this common in a system that is seven years old.
I brought the house brand new the furnance came with it.
I have had it serviced each year. I also have several vents closed
off because of rooms that I do not use. It is a split level home.
