From time to time a dryer's drum can fail either by jamming up, a technical error with the machine or from a broken dryer belt. In most cases a broken dryer belt is the cause and can be replaced without calling out a technician or engineer In other instances the cause could be an opened or unlocked dryer door, debris inside the dryer or the incorrect setting for the dryer. Old dryers are more likely to have snapped dryer belts as the belt can become worn over time and prone to breaking.
Ensure the dryer is not overloaded with saturated clothes as this will cause the belt to slip. If the dryer is overloaded, remove the clothes and allow the dryer belt to dry off for 1 to 2 hours. Check that the dryer door is also fully closed as the drum will not move unless the door is locked.
Move the drum with your hand. If the drum moves freely with very little force applied then you may have a broken belt; in this case move to step 3. If the drum is seized and does not move then it is recommended you contact a technician or professional; the dryer may have a more serious fault.
Unplug the dryer from the socket and move it away from the wall. Remove the top panel of the dryer by leaning the dryer towards you and unscrewing the four screws at the corners of the panel. Samsung dryers normally require the screws to be fully removed before the panel can be lifted - the actual location and amount of screws will vary depending on your Samsung model but should be visible. Place the panel aside once unscrewed and lifted away from the dryer.
Remove the front panel of the dryer. Lean the dryer towards you and remove the screws holding the front panel in place before gently lifting the panel away. Again, the amount of screws in place will vary depending on your Samsung model.
Locate the dryer drum, a large barrel in the middle of the dryer with a thin rubber ring around it. The rubber ring is the dryer belt which may need replacing. Rub along the dryer belt to find any holes, snaps or tears. If there seems to be no fault with your dryer belt call a technician or professional. If there is a fault you can move to step 7 to replace the belt.
Remove the old belt from the dryer. Firmly pull the belt away from the drum and pull the belt out; because the belt is already damaged it should be easier to remove from the gears and drum edges.
Slide the new belt under the dryer drum and then around the drum. Ensure the belt is not twisted and locate the pulley wheel which is usually located at the back of the dryer and resembles two gears. Place the belt through the middle of the two gears and over the larger, higher gear and then below the smaller, lower gear. Your belt will resemble an "S" shape if installed correctly.
Reassemble the dryer, plug the dryer back in and refer to your manual to place your dryer into "test" mode to test the performance of the drum.
