While I don't know about your specific dryer, most dryers are set up the same. I just replaced the belt on my Maytag LDE8404ACE. It was easy. The hard part was cleaning out 14 years worth of lint and fuzz that coated everything inside. Here's the instructions:
1. Unplug the dryer or disconnect power.
2. Remove the front panel. There are two screws, each is about 4 inches up from the bottom of the front panel. Unscrew them. Then hold the front panel along the bottom edge and pull it away from the dryer. Once it's away enough, the clamps along the top will pop and disengage from the dryer. Be sure to note the wires connected to the door switch are connected to the dryer. Disconnect them if you need to move the panel away from the dryer.
3. With the front panel off, you should be able to reach inside the dryer to remove the old, broken belt.
4. Remove the tumbler from the dryer. It's held in place by the tumbler front which is secured by 4 screws, 2 on each side. That piece will pull straight out toward you. With the tumbler front out of the way, the tumbler itself will come straight out as well. I recommend taking it out and cleaning the inside of your dryer while it's open. A vacuum hose works great. Also, check the pulley and the back two wheels that the tumbler rests on to make sure they turn easily. If not, you may want to grease them. Also, it's normal for the idler pulley to appear to be loose and wiggle in place. Once a new belt is installed, it's under tension from the spring so any play that exists shouldn't be a problem.
5. put the new belt around the tumbler with the smooth side of the belt against the tumbler. Use the old belt marks on the tumbler to align the new belt. It's easier to hook the belt to the idler pulley and motor pulley from the back. So we'll get to that part in a minute. Just let the belt hang loose for now.
6. Reinstall the tumbler front and secure with the 4 screws you removed earlier.
7. Reconnect the wires to the door switch, if you removed them earlier.
8. Reinstall the front panel, reversing the steps you took to remove it in #2 above.
9. Go to the back of the dryer and remove the access panel along the bottom right hand side.
10. From there, reach in pull the dryer belt around the idler pulley. Then take the belt on the left side of the pulley and move both the belt and the idler pulley to the right, until you can get the grooved side of the belt onto the motor pulley. I've attached a diagram with instructions.
11. Once connected, manually turn the tumbler so that the belt will align and make sure the tumbler turns as easily as it did when you first removed it.
12. If the belt looks good and you've manually turned the tumbler at least one full revolution (to ensure the belt didn't get twisted), then plug the dryer in and turn it on to make sure it works correctly. If so, then re-attach the access panel on the back of the dryer. You're done!
