This problem, as devastating as it may seem isn’t difficult to repair in most cases. First, let’s take a look at the causes. As your dryer wears, the drum seals also wear out creating a gap for clothes to get stuck in. As the size of the gap increases, so does the likelihood of clothes getting stuck or the dryer ripping your clothes. The fix for this is replacing the drum seal(s). The gap is between the drum lip and the bulkhead in the front that supports the drum, and in the rear where the support rollers are located.
Replace the drum seals
Of all the reasons for torn or stained clothes, the most common problem is worn out drum seals. Depending on the type of dryer you have, the drum seals could be on the front and back of the drum. Whirlpool and some GE dryers often use Mylar strips in place of the front drum seals to help stop the gap from starting in the first place. If you’re replacing fiber seals, you’ll need to glue them on using a high temperature adhesive. Find out if the type of seal you purchase includes a tube of this adhesive.
Worn support rollers
While worn rollers can cause the problem, it’s not as common as the drum seals. When rollers wear out they usually squeak or start to wobble. In either case the symptom is hard to miss. For good measure, if you end up replacing the drum seals you might want to replace the support rollers as well.
Some dryers, usually GE and Maytag use Mylar and fiber pads to help support the dryer drum and are located on the front bulkhead. When these wear out a gap is created like that mentioned above, in addition to the added noise during operation.
The dryer drum has baffles installed on the inside of the drum to make spinning the clothes easier and more effective for drying. Over time, these plastic baffles can warp from heat and use causing yet another gap for clothes to get caught in. Carefully check the mating surfaces of the baffles to be sure there are no gaps present. Also check if they’re loose. Sometimes as they push the heavy, wet clothes around the drum they tilt ever so slightly and allow garments to get caught. As a side note, this is the same reason coins and small objects get caught in the baffles and contribute to that rhythmic sound emanating from your dryer.
