We have one, maybe 5 years old.
Problem: Noise and vibration. Loud when started and quieter after running a while.
Cause: The dryer is a conventional drum setup, with two support rollers in the back and the front running on plastic sliders and felt seals. The belt wraps around the drum to turn it and goes through some pulleys, one of which spins the air blower. This pulls air from the front of the drum below the door and sends it out to the exhaust. The back of the drum has an air duct where hot air is sucked in with a duct to a hot air "stove" on the bottom of the dryer floor to the right of center. The problem was that the blower blades were packed with lint. The cause of this is (1) wife like cotton flannel sheets, (2) the lint filter does not catch all of that lint.
Unplug the dryer!!!!!!!!!!!!!!!!!!
The door must first be removed. There are two #2 Philips screws, which are counter sunk and longer. There are to plastic parts on the opposite hand with shorter screws that are flat as to not crack the plastic. These are the only bright chrome screws that you will find.
With those four screws removed, pull out the tops of the front panel. Swing out and lift off of the spring clips at the bottom. To refit you will have to press down on the front panel to depress those spring clips. You can then put one foot on the bottom door frame to make that easier. Note the spring clips and holes at the top. Shift the front panel slightly to the door hinged side... note the slots that the hinge inserts into and the need for this alignment so the hinge can be inserted and the holes not occluded.
With the front panel out of the way: Remove two long bright screws at the bottom of the door opening that are now exposed. These are the only screws of this type that you will find. Now start removing screws around the door frame section. These are black phsophated and are best removed with a 5/16" nut driver. Two are short, get a marker pen and put dots at the locations where you find them. Two of these screws will also release the thick "hooks" that secure the top of the dryer. Remove these and note that the dryer can now be lifted at the front. You can now remove the drum front section.
Note: when doing the above: locate the screws that do though cutouts of the door frame that do not secure it. Leave these in place as these secure the front of the drum.
Note: There is a light and a clip securing wires. Note wire routing. The lamp holder has a securing clip as part of the plastic. You can depress that and remove the lamp housing and bulb as a unit. With that removed, the door frame can be moved with its attached wires. I found that I could rotate it top to bottom and set to one side to the right and wires did not need to be removed.
Remove the two screws holding the front drum section and set this aside. You will want to clean its rubber seal and inside with a tooth brush or whatever and vacuum out.
The blower is not exposed front, bottom and left of center. It has serveral 1/4" screws that need a 1/4" nut driver to remove. There is one more to the right and behind a bit back of the thermostat wires. Remove the blower cover and set aside with wires intact. Clean with a brush.
The plastic blower wheel is not exposed. This needs to be cleaned. In my case many of the "slots" were choked with lint. Use fingers, brush to clean the wheel and blower scroll case.
Vacuum inside of dryer, blower, lint box duct and bottom ledge of the front panel.
Inspect the surface of the outside of the drum that rubs on the felt seals at the front and rear. This can have deposits from things that should not have gone through the dryer. I needed to clean mine and Windex on a cloth worked well. Most of this problem will be at the front seals. You can rotate the drum by turning the blower wheel while using the other hand to push back the roller and otherwise keep it on the rollers on the back. I also wiped these seal contact areas with a bit of Armour-All which is a good lubricant for plastic and painted surfaces such as this.
Now put back together. Get the lamp remounted with the same wire routing and secured with the clip. Get the drum front up agaist the blower and secure its two screws that do not attack the door frame.
Cause of problem. The blower blades are curved which causes lint to build up on them. While this is a good design for moving air, it is quite inappropriate for blower moving dust and lint. This looks like it is something that needs to be done a perventatuve maintenance.
