Hello,
What is the model number? If your lint screen is accessed from the top of the dryer you have to flip the door open and remove the 2 screws. Then place a putty knife between the top and front panels and push in on the 2 clips to lift the top. Once the top is raised you should see 2 screws inside the front panel that will get the front panel off. Now you can access the belt.
