I have a two year old Big-E. There seems to be a great deal of heat lost since it was new. I cleaned the blowers. Replaced the convection blower with the "new blower" from Breckwell. For lack of technical terms the new blower seems to have less force. I have heard of other blowers that might fit. Does anybody have any comment on these aftermarket blowers? Any model numbers? What should be the air temp coming out with the stove set at 3? I am in need of any information that may be out there. Please Help!
