Complaint: 10 year old dryer is noisy and getting worse.
Unplugged the dyer cord and removed the front of the dryer. It was obvious what the problem was after looking at the blower wheel.
The blower wheel was being thrown off balance from all that lint packed in it.
Solution: Clean all the lint out of the blower wheel and the rest of the dryer. Also check the dryer vent to make sure it was clear of any lint and did not have any kinks or other restrictions.
