First check the tumblers inside the drum to make sure that none of them are loose. AFter that you'll need to gain access to the inner workings of the machine.
There are 4 different designs that used on these dryers and each one has its own specific way to access the element, blower, fuses. etc In this FAQ I will describe each design and method to access for each one. ---------------Design 1: This design for this dryer has the heating components located in the front of the machine, which means to gain access you'll have to lift the top and remove the front. You can visually verify this specific type because the lint screen is located inside the dryer requiring you to open the door to gain access to it. As with any do itself repair, always unplug the machine before you start. Here's the method of access listed in numerical order. 1) Remove the lower kick plate by pressing in the two clips, one on each side located in between the upper and lower portion of the front In doing this you'll gain access to the element, located on the right hand side facing, the high limit and thermostat fuse located on the element, the cycling thermostat, located on the blower housing, and thermal fuse, located next to the cycling thermostat. In gas models the gas coils and ignitor may be located on the left hand side facing. If changing the belt, rollers or motor, continue to step two. 2) Lift the top by placing a flat head screwdriver in between the front and the top of the dryer and pry it upwards. In some cases there are two metal clips, one on the left and one on the right, that need to be pushed forward to lift the top up. 3) With the top up and the kickplate removed take the door springs off, one on each side, and remove the door by taking out the 4 screws one upper left and right, one lower left and right, off and don't forget to disconnect your door switch-----------------Design 2 : In this design the heating components are located in the rear of the machine. All you have to do is get behind the dryer, remove the 9 1/4" screws and remove the panel. The element eill on the right had side with the two fuses located on it, the cycle and thermal fuse will be on the lower left on the blower housing. To access the belt, rollers etc, remove the lint trap on top, take out the two screws that are underneath it and using a flat head screwdriver pop the top up. Next, located the two screws that are on the upper left and right inside front of the machine that hold the front. Remove these and then you'll be able to lift and pull the dryer front completely off.--------------Design 3 : In this design the components are located in the front of the machine, but to access them you'll follow the method used in design 2 for accessing the belt, rollers, etc.take out the two screws that are underneath it and using a flat head screwdriver pop the top up. Next, located the two screws that are on the upper left and right inside front of the machine that hold the front. Remove these and then you'll be able to lift and pull the dryer front completely off. The set up will be like design one.--------------- Note: The best way to determine if your dryer is desgin 2 or 3, remove lint trap and pop the top. When you've got this done, you'll be able to look in between the inside rear wall and the rear panel and see if the element, fuses atc are there. If not it will be design 3---------Design 4 : HE, HE2, Duet, etc the way you take the top off is a little different. For these machines, there are 3 to 4 screws located on the top back side you'll need to remove, and then the dryer top can be slid back and removed. From there you'll remove the kickplate in come cases by taking the 3 or 4 screws off located at the bottom of the kickplate. With that removed you will be able to remove the front, but only after you remmove the control panel. The In some cases the components will be located in the rear like the second design
