Hi if you really want to have this one serviced the best thing to do is bring in to a Local Best Buy or Sears, they will send it out, and repair it like new. They are fair priced, and they do both do a great job of this;-) I know I worked for both as a repair technician.
Its likely a belt or a pinch roller is to blame for the trouble on this one.
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you and have a great day!
