How to remove the drum of GE brand dryers :

Opening the cabinet and removing the drum of GE dryer models
Note:
Disconnect the power source to your dryer before you begin to remove the drum. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel.

Pull your dryer out from the wall. Behind it, on the bottom, you will find a lower panel that will give you access to the unit's belt tensioner (also known as an idler pulley arm). Remove the screws holding this panel in place, and then remove the panel itself. Reach inside and release the belt tension by removing the belt from the motor pinion.

Older GE dryer models have a small drum bearing inspection plate in the center of the back of the dryer. This drum bearing inspection plate provides access to the dryer's circlip (also known as an e-ring). This clip holds the rear drum shaft in place. Newer models do not have this circlip or the drum bearing inspection plate.

If yours is an older GE model with an inspection plate, remove the plate now. It will be held in place with a single screw. With the plate removed, you will be able to see the drum support shaft and the e-ring (circlip) holding the shaft in place. Use a small screwdriver to remove the e-ring. You may also want to use a magnet to keep the circlip from falling into the dryer. You will also find several metal and nylon shims between the bearing and the e-ring, inside the bearing, and between the bearing and the drum. Take careful note of how they come off so that you will be able to put them back on again in the right order.

Now remove the front panel of the dryer. There are a couple of different ways this is accomplished. Whichever method you use is dependent upon your model. Some older models have two spring catch clips under the cabinet top, one on the left side, and one on the right side of the front. Use a putty knife, or some other flat and thin object to wedge in under the cabinet top. Release both spring catches and lift the cabinet top off the dryer. In some newer models, there will be screws joining the cabinet front panel to the cabinet top. You will have to open the door in order to find these screws. Once they are found, remove them and then slide the cabinet top forward and lift it off the unit.

Next, there are two screws located in the bottom of the front panel, one in each corner. Loosen these, but do not remove them just yet. Locate and remove the two screws at the top inside of the dryer's front panel. Again, there is one screw in each corner. Proceed to remove the other two screws you have just loosened. Disconnect the door switch wires and then lift the front panel off your dryer. With the front panel removed, lift the drum and slide it out of the dryer.

NOTE: In some models, you will have to remove the dryer drum glides before you can remove the drum. Also, now that the interior of your dryer is completely exposed, it might be a good time to vacuum out all of the dust and lint that has built up in there.
