Many XXV owners are having trouble with their distribution blowers. I have changed many . I believe the problem is that it's too hot where the motor sits and the bearings don't last long. The same blower in a free standing accentra lasts longer. I have made a weldment specifically for the XXV. I use it to attach a different blower that mounts on the outside of the stove. Email me if you want one. I don't sell them online. [email protected]
