Hotpoint NVL333EY Electric dryer blows thermal fuse

I had the same thing happen, I replaced the thermal cutoff and made sure no lint build up. It lasted a week then blew again. I then replaced it again and got to thinking why it would blow. I then took apart the exaust inside the dryer running fron the drum to the motor and right before the motor was a build up of lint ane particals that was almost like compressed sawdust which was blocking half of the line. I cleaned this out and it seemed to work much better.
