I am having problem with my Luxaire furnace it will not light it only blows cold air. If I put my hands under the exhaust duct when I restart it it will light.
How and where do I find the LED it is an outside rooftop unit.RhondaBjd said:Locate the control board, and find the LED that is going to tell you a flash code.
Once you have this we may be able to help you in some way.
I have had the worst of times with my Luxaire model (matter of fact, had the same problem just moments ago...about a weekly chore). I've gotten pretty good at taking the burners out, using a flexible wire brush that fits inside and blowing them out. I finished our basement off a year ago, and I think dust may have settled in the control. But, after cleaning the blowers out, it seems to light regularly...for the next week or so. I did notice tonight that the seal around the intake by the fan motor was damaged and was blowing air down towards the first burner. After cleaning the blowers and placing a finger over that draft, it lit right up. So, advice, clean the blowers (you can do this yourself). If that doesn't work, check for internal drafts.Unregistered said:I am having problem with my Luxaire furnace it will not light it only blows cold air.
