there are 4 rollers in this dryer, and YES they are probably the problem. This is in reality a whirlpool under the LG label and is very easy to repair. remove the top then you access the screws that hold the front panel on from the inside...they are on the top corners inside the unit....be sure to unplug the dryer first...thanks and have a happy and safe 2010
