When I turn on my Maytag Atlantis dryer, it makes a horrible screeching/squeaking noise. I have taken off the front panel and tried to see where the sound is coming from, but cannot determine where. Below the drum is a spring/idler where it then attaches to the spring wire harness. I think the vibration of the dryer operation is causing this all to make the noise. How do I gain access to this area and fix the noise problem?
Thanks in advance.

It is in the bearing for the drum. You need to clean it and change the bearing. Read the following:
You will have to clean the drier out thoroughly. Every air duct will have to be removed and scraped and washed out to remove baked on lint deposits which is like concrete lining. This will burn so the manufacturer has installed the safeties to keep from having a house fire. Driers were the number one cause of fires at one time. Look at: http://www.youtube.com/watch?v=MMP7BW1lLs4 to see how. Also: http://www.youtube.com/watch?v=iBiRw-KElC4 ; http://www.youtube.com/watch?v=yFTZGgVisCI
When you finish cleaning the drier it is best to also replace the belt, too, because you do not want to have to disassemble it again, and if the belt is over two years old you should replace it.

Note that on most of the videos it does not show them washing out the parts, but this is important because it's the only way to really get the parts clean, just don't get motor wet or the capacitor if it has one. Vacuum out motor. I would move the drier out to your garage to have plenty of space to work. You also want to check your vent and clean it, also. The job is really easier than it sounds. There is no shortcut that will work; it has to be cleaned well. Before you re-assemble it make sure to use white lithium grease (high-temp grease) and grease all bearings. Just vacuuming out the dryer a little does little good. You also want to check the vent and clean it out. When you are done you will have a new dryer and it will dry like new again. You want to clean it like this every two years or every year with many children. In addition to cleaning it you will have to change the drum bearing which you can see on YouTube. DrTom4444
