Above the blower, the blue wire kept burning and got shorter and shorter to the point that the metal above the black little box got burned as well. It has been doing that since I first bought it while on the guarantee. So the heat does not come any more but the blower still work. Who can I talk to to replace the broken part. I want a phone number and please e mail me back. Nicole at nicrondeau@yahoo.ca Cornwall, Ontario, Canada.
