Close the dryer door so that it latches and pull the dryer out from the wall so you can move behind the appliance. Unplug the power cord from the wall outlet behind the dryer and close the gas valve knob, if you have a gas dryer.
Lift the lint screen cover on the top of the dryer and pull the lint screen out of its slot to remove the two screws underneath. Set aside the screws and lint screen. If your lint screen is inside the dryer door, skip this step.
Insert a flat-blade screwdriver in the left and right corners of the dryer front panel at the top, in the narrow gap where the panel meets the top of the dryer. Pry up the top of the dryer gently, taking care not to pull loose any wiring.
Pull out the metal clip on the top-left and -right corners of the front panel, using pliers. Removing the clips disengages the front panel completely from the dryer top.
Extract the screws on the left and right edge of the front panel and the kick panel below the front panel. Save the screws for reconnecting later.
Pull forward from the top of the front panel to disengage the part from the cabinet, then set aside. You can now access the front of the dryer drum, motor, drive belt and other parts in the front of the appliance.
