The drum support roller holds the drum in place while allowing the drum to rotate on the support wheels. The drum support roller usually makes a scraping or thumping noise when it's damaged. The drum thumps quickly when the drum support roller has a flat spot. It scrapes or squeals when the bearing of the drum support roller is damaged or worn out. Unplug the dryer and open the cabinet to examine the drum support roller before ordering the replacement part. Before you begin, wear work gloves to protect your hands. Unplug the dryer. Pull the lint screen out of the housing in the top panel of the dryer. Use a Phillips screwdriver to remove the 2 screws that secure the lint screen housing to the top panel. Push a putty knife under the lid near the left and right edges of the front of the dryer. Lift the top and prop it securely against the wall behind the dryer. Use a slot screwdriver to release the locking tab on the wire harness plug for the door switch. Use a nut driver to remove the front panel mounting screws from the inside of the cabinet. Pull the front panel forward slightly, and then lift and unhook it from the 2 bottom hangers. Pull the front panel off of the dryer and set it aside. Note the configuration of the belt on the idler pulley and the motor pulley before removing it—you might find it helpful to take a digital picture so that you remember how to reinstall it. Push the idler pulley to the right to release tension on the drive belt. Pull the drive belt off of the idler pulley and the motor pulley. Use the drive belt that you just released from the pulleys to lift the drum up and out of the dryer cabinet. Use a slot screwdriver to pry the triangular washer off the front of the drum support roller. Pull the drum support roller off of the front of the shaft. Push the new drum support roller onto the shaft and secure it with the triangular washer. Place the rear of the drum on top of the support roller that's on the rear panel inside the dryer cabinet. Lift the front of the drum to access the drive motor and idler pulley. Thread the drive belt through the idler pulley. Push the idler pulley to the right and loop the drive belt over the motor pulley. Position the front panel on the hangers at the bottom of the cabinet. Line up the mounting holes and reinstall the screws in the top of the front panel to secure it to the dryer cabinet. Plug the wire harness back into the plug on the door switch. Lower the top panel and snap it into place. Reinstall the screws in the lint duct housing and reinstall the lint screen. Plug the dryer into the wall outlet.
