my blendtec designer675 motor is smokinng and out of warranty of 7 years. Any suggestions to fix it? Thanks!
Jayshree Patel could be worn out brushes. If they are worn they can arc which will leave a burning smell as well as some smoke. Of course, if the smoke is excessive you do not want to use your blender and replace the motor since it would be a bigger issue, like some of the windings on the motor breaking down etc. Adding images to an existing question
