AEM407L Speed Queen Dryer

Wasn't the belt!! Changed it anyway. Should have come here earlier. That mistake added several days to the repair waiting for a second batch of the right parts. Became a pro at taking the dryer apart and reassembling, though! Easy job, just take your time and mark your wires, if you need to.
Followed other people's excellent instru ... Read more ctions. Clean out all the dust bunnies. Schematics were a great resource. Those and the prices made me a repeat customer.
The shaft of the Idler Lever wheel was the cause, but decided, since I had it apart, to spend a little more money and replace both Drum Support Rollers and the Roller Bracket and Shaft Assembly. They showed some wear, and the parts were very inexpensive. Make sure you have snap ring pliers with prongs that are smaller than the standard 0.40 to save some aggravation with the Drum Rollers. $5 tool. Total parts were less than $60. Probably saved $150+ in labor. Quieter than ever now. Thanks!

Remove front panel, lint basket, motor mounts,exhaust hood, front drum brackets. Then slip serpentine belt around drum, pressure w/ tension idler pulley and slip around drive motor spindle. Replace all parts in reverse order (a two person job).
Vacuumed inside of dryer (full of lint.)

First I read all of the other stories about this problem so I would have the correct parts. At $6 a roller, decided to get all 3 & a belt. Pulled the lower panel off (2 bolts), then the door (2 bolts). Marked the door switch wires. Took 2 bolts out of the top & tilted it back. I found this the easiest way to access the drum. Mark 2 wires ... Read more before disconnecting them from the top. All bolts are 5/16". Removed the plastic piece that connects the lint trap to the blower (3 screws). Have to access these from inside the drum. Removed the belt, then the drum. The bad roller was the belt tension roller. Can't get to the snap ring from the front of the dryer for this roller. The 2 rollers in the back you can get to without removing the drum completely. Very easy to replace all rollers with the drum out. Also very easy to re-assemble. Buy or borrow a good set of snap ring pliers. Make sure you diagram the proper belt route if you don't have a picture. I printed a picture off this web site. Have someone hold the drum up so you can get the belt on, otherwise the entire repair is a 1 person job. Went back together in about 10 minutes. Total cost $40.00 parts & shipping.
