This dryer is making a very high pitched screeching noisy.It heats and works but makes this noise.What could be wrong with this thing?Can some one help me in the repair of this dryer?Thanks for your time.

The two most common things that make these dryers noisy are bad drum support rollers, or a bad idler pulley that keeps tension on the dryer belt. For this dryer we sell a kit that includes all four drum rollers, idler pulley, and belt.
