Instructions

Do not proceed until you are confident that you understand all of the steps and are capable of completing the repair. Some repairs should only be performed by a qualified technician.

This video shows a gas dryer. For an electric dryer, skip the step for shutting off the gas.

Step 1: Shut off the power

Unplug the dryer. If you have a gas dryer, shut off the gas.

Step 2: Remove the lint screen

Pull the lint screen out of the housing in the top panel of the dryer.

Step 3: Remove the lint screen housing screws

Use a Phillips screwdriver to remove the 2 screws that secure the lint screen housing to the top panel.

Step 4: Raise the cabinet top

To release the clips that lock the top of the dryer in place, 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. 

Step 5: Disconnect the door switch wire harness

Use a slot screwdriver to release the locking tab on the wire harness plug for the door switch. Disconnect the wire harness. 

Step 6: Remove the front panel

Use a 5/16" 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.

Step 7: Remove the drum

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 of it so you know 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. Pull the drum out of the dryer and set it aside. 

 Tip: Use the drive belt that you just released from the pulleys to lift the drum up and out of the dryer cabinet.

Step 8: Remove the drum support roller

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. 

 Tip: While the cabinet is open, vacuum the dust and lint from inside the dryer cabinet.

Step 9: Install the new drum support roller

Push the new drum support roller onto the shaft and secure it with the triangular washer.

Step 10: Reinstall the drum

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. Referring to the digital picture of the configuration, thread the drive belt through the idler pulley. Push the idler pulley to the right and loop the drive belt over the motor pulley. 

Step 11: Reinstall the front panel

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.

Step 12: Reconnect the door switch wire harness

Plug the wire harness back into the plug on the door switch. Make sure the locking tab engages properly.

Step 13: Reassemble the dryer

Lower the top panel and snap it into place. Reinstall the screws in the lint duct housing and reinstall the lint screen.

Step 14: Restore power to the dryer

Plug the dryer into the wall outlet. If it's a gas dryer, turn on the gas supply to the dryer.
