A damaged or worn dryer belt can affect the dryer’s heating and keep the dryer from tumbling clothes. The best way to fix the problem is to replace the belt. Contact the dryer’s manufacturer or an appliance store to order a replacement belt compatible with your dryer. Consult the owner’s manual before making any major adjustments.
Disconnect the dryer unit from its socket. Locate the lint screen on the top of the dryer or inside the door. If a latch isn't available, use a Phillips screwdriver to remove the screws that secure the screen in place.
Slide a putty knife between the dryer's front panel from its top corners to loosen it up. Lift the panel to expose the release clip on the side panel of the dryer's cabinet. Twist the release clockwise to unlatch the foot panel.
Place a phone book or wooden block inside the foot panel and underneath the drum so it can support the front panel once it is removed. Only loosen the screws at the bottom of the front panel on the dryer's sides. Remove the screws inside the cabinet that hold the front panel and dryer sides in place.
Lean the front panel out from the dryer enough to have extra room when you replace the belt. Slip the new belt over the top part of the drum.
Slide a replacement belt over the faulty belt on the drum; be sure that the grooved parts of the new belt are facing down. Slip the old belt from underneath the new one.
Push the idler pulley toward the motor. Loop the rest of the belt around the dryer motor's pulley.
Reinstall the front panel. Rotate the drum counterclockwise a few turns with your hands to make sure it is tracking in correct. Reconnect the dryer to the power socket. Turn the dryer on for a test run.
