Note: You may want to consider replacing the 2 Drum Support rollers at this time (while your in there)

1. UNPLUG YOUR DRYER FIRST.

2. Using a phillips head screw driver - Remove 2 screws that secure the dryer door hinges to the frame, Lift door very slightly to unhook hinges and pull out door with hinges attached as straight as possible, set aside. Remove the 2 plastic tabs from the opposing side of the door hinge also secured by screws.

3. Remove the front panel (panel is shaped like a football goal post) by tilting out the top ends of the front panel toward you, then lift up to remove panel from the bottom metal retaining tabs.

4. Remove the 2 hexhead screws from the 2 retaining clips (security hooks) that secure the top
of the dryer closed.

5. Systematically remove the hexhead screws from the rest of the front of "shroud" (it holds (suspends) the drum in place between the front and back of the dryer).

*** I didn't disconnect any wires, I carefully swung out each piece that had wires attached, propped up those parts vertically ensuring no strain on the attached wires. Others may want to disconnect wires to avoid breaking or damaging them.

6. Vacuum out any dust/lint that may be present.

7. Draw a quick diagram of how the underside of the belt is threaded on the idler pulley and motor pully first. Release the tension of the belt from the underside of the drum. The easiest way is to push the idler pulley arm away from the belt and slide off the belt from the idler pulley and motor pulley. Slide the drum out.

8. Remove the hexhead screw from the bottom of the idler arm. Disconnect from retaining spring.

9. You may only need to replace just the Idler Pulley Wheel. I recommend replacing as a "unit" the Idler Pulley Wheel, Idler Arm, Ring-E and Idler Shaft Washer(s) - then you can just swap out the old one for the new one.

10. Reassemble

(When reassembling the belt - place around drum first and slide drum in place. Now from the underside-place (drape) belt around the motor pulley (it will be very loose) Now push the idler pulley arm toward the motor pulley, engage the left side of the belt around the idler pulley and slowly allow idler pulley to increase its tension on the belt) You can test manually by rotating the drum by hand to ensure proper movement.)
