That's what I have heard. These are propane so maybe that's why they are still going. These units really pissed a lot of customers off, one contractor got sued awhile back over one. They just suck to work on.
Ya I think the contractor got sued, Lennox should have. I don't know the specifics just what I heard. The guy used to work for our company years ago and wasn't the most quality conscious. You know how it is though, every time something fails your the ass hole not the person who manufactured the equipment ha ha.
