Went to cut a sign today and right as sign started to but I got the check cut motor error. checked and had no luck. Tried the motor test and motor would not spin. Checked brushes and found this. Would this be a reason motor is not working! I am not the electric motor inclined kind of person! I was able to order a set IN STOCK from sears parts today (CB001 Carbon Brush 001) I hope these are the right set. Carvrwright said they won't even know when they are going to get any until late next week! (was even thinking about upgrading the cutting motor but they don't have any of those either!
