I have an Amana dryer - model#ALG443RAW and need to replace the belt.
How do I do this? Is it better to have a repair person do it or is it simple enough to do myself?

Remove the cabinet front by removing the 2 screws at the lower front of unit. Swing the bottom out and remove the 2 clips at the top.Once removed the belt will be at the back side of the unit. It goes around the drum the motor and the idler pulley. Not hard to do if you are fairly handy.
