DIY steps
- Before starting, ensure your safety by unplugging the dryer from the power outlet and wearing protective gloves. Locate the dryer's rear panel, which you'll need to remove to access the drum belt. Use a screwdriver to remove the screws holding the panel in place.
- Next, locate the idler pulley and remove the screw holding it in place. Gently pull the pulley away from the belt to release the tension. Remove the old belt from the pulley and the drum.
- Take the new drum belt and wrap it around the drum, ensuring it's properly seated in the grooves. Reattach the idler pulley and re-tighten the screw. Make sure the belt is properly aligned and not twisted.
- Reassemble the dryer by replacing the rear panel and reattaching it with the screws you removed earlier. Plug in the dryer and test it to ensure the drum is rotating smoothly and the belt is not slipping.
- Verify that the dryer is working correctly by running a test cycle. Check for any unusual noises or vibrations, which could indicate a problem with the new belt or other components.
- Finally, clean up any mess or debris from the repair, and dispose of the old belt responsibly.
