I was told yesterday that the blower motor had a broken bearing and that the blow fan is out of alignment. My sister also bought her Lennox furnace in 1996 (installed by the same heating and cooling company) and had the same problem last year. Have you heard of some "defect" in their 1996 models that might be on a recall? A man at my work said those motors should last at least 10 years. Please advise. Thanks.
