The clothes was getting stuck on the tumbler

First I removed the 2 screws on the back. These 2 screws hold the top cover. I also used a flat screw driver to press the 2 locks that hold the top cover, they are located in front and under the top cover . Then I removed the 2 screws that hold the front cover. After removing the front cover I replaced the drum glider and the seal-basket lower. Now my dryer is working perfectly...
