The drum must be removed to service the electric heaters, or to remove the blower or motor, to replace the rear drum bearing.
In certain models, you will also need to remove the front drum support glides to get the drum out. you should be able to lift and slide the dryer drum straight outward. While the machine is open, vacuum out all accumulated lint. Be careful not to knock any wires loose.
Older models have a circlip (“E”- ring) holding the rear drum shaft in place and a small drum bearing inspection plate in the center of the rear of the dryer to access this circlip. (See Figure GE-3) If you have an inspection plate, remove it now. Later models do not have this inspection plate, nor the circlip.
Inside the inspection plate, you will see the drum support shaft and an “E-“ring holding it in place. Remove the “E-“ring with a small screwdriver. If you have a magnet, you may also be able to use it to avoid dropping the ring inside the dryer. There are spacer shims between the bearing and the “E-“ring. There are more shims inside the bearing, between the bearing and the drum. Some are nylon and some are metal. Note how they come off, and make sure you put the shims back on the same way they come off.
