Replace Your Dryer’s Drive Belt to Stop the Thumping Noise

  1. Disconnect the dryer from the wall. Unplug the power cord from the electrical outlet — safety first, people. Then, pull the dryer away from the wall so you can easily access every part of it.

Pro Tip: Take pictures as you go along so you can remember what everything looked like before you took it apart. Trust us — you’ll need them when you’re putting Humpty back together again.

  1. Remove the lint screen, housing and all. The lint screen comes out with a firm tug but you’ll need a screwdriver to get the housing out. Unscrew the screws holding it in place so you can pull the top of the dryer away from the sides.

  2. Remove the top dryer panel. Slide a putty knife under the right and then the left front-facing edges of the panel. You’ll hear the top make a pop and the panel will swing open so you can prop it up. No worries if the panel pops off entirely — just place it to the side.

  3. Unplug the door switch wire harness. Look for a white plug that’s connecting a side panel to the front panel of the dryer. Psst...If you’re having trouble finding it, look carefully at the corners of the dryer panels. Unplug it so you can pull the panels apart.

  4. Remove the front panel mounting screws and pull off the front panel. Use a nut driver to take out the screws that attach the front panel to the side panels. These are located along both inside corners of the machine. Then pull the front panel out, away from the drum, and up. Ta-da — it’s unhooked from the bottom panel.

  5. Check the drive belt. This thin strip of rubber goes around the entire drum and creates the friction needed to keep the drum spinning. Over time, it wears out and cracks. Especially if the support rollers aren’t functioning smoothly. If it looks damaged, grab a pair of scissors and cut it free. If it’s just misaligned, you can adjust its position. ( should loop over the the dryer’s drum, under a pulley and around another pulley.)

  6. Remove the dryer drum. Grasp the front end of the dryer drum and pull it forward, sliding it out of the dryer housing. You’ll need to balance it as you pull so it’ll slide out easily. While everything’s out, take the opportunity to clean, it’ll help your dryer run more efficiently.

  7. Get a replacement belt. Head over to your local hardware store with pictures of your dryer and your old dryer belt. Don’t forget to jot down the make and model of your dryer so you can easily find the correct parts.

  8. Install the new belt. With the drum still out, install the new dryer belt by wrapping it around the drum. Slide the drum back into the dryer housing and wrap the belt under the idler pulley and around the drive pulley (you took a picture of what it looked like before, right?). Double check that everything aligns correctly and fits in the proper grooves.

  9. Put the dryer back together again. Don’t be afraid to use your photo references. Replace the front panel, wire harness and lint screen. Finish the job by plugging the dryer back in and repositioning it against the wall.
