Asko T720 clothes dryer - thumping noise like the drum is damaged and shakes when going.
The drum of the dryer is usually turned by a motor-and-belt assembly. There are two very clear signs that the belt is malfunctioning: You can easily spin the drum by hand when the dryer is off, or you hear a heavy thumping sound coming from the drum when the dryer is running. Here's how to test and replace the drum belt:
Step 1: Locate the belt by removing the back or front service panel. Depending on the type of dryer you own, you may have to prop up the drum to keep it from sagging. Don't let the drum hang; the bolts that hold it in the cabinet could be damaged. Don't remove any more parts than necessary.
Step 2: Identify the belt. The old belt may be threaded around the idler pulley and motor drive shaft. Draw a diagram showing how the pulley is installed so you'll be able to replace it properly. If the old belt is worn or frayed, but not broken, leave it around the drum as a pattern for positioning the new belt; cut the old belt and remove it when the new belt is in position.
Step 3: Remove the old belt from the pulleys and stretch the replacement belt into place. The new belt must extend around the dryer drum and the pulleys. The trick is to align the belt on the drum with the pulleys -- the ribs on the new belt go against the drum.
Step 4: Once the belt is aligned, turn the drum by hand, if possible, to make sure the belt is tracking. You may have to reassemble part of the cabinet to do this.
