What you need to know before you start

The drum belt on a Samsung dryer wears out over time and eventually snaps, leaving your dryer unable to tumble clothes. Replacing it is a job you can do yourself with basic tools—no special skills required—and it typically takes 30 to 45 minutes. The belt costs between $30 and $60 depending on your model, and you'll need a screwdriver, a putty knife or flathead screwdriver, and possibly a socket wrench.

Before you begin, unplug the dryer from the wall outlet. This is not optional. Even though you're not working with electrical wiring directly, the drum can still turn unexpectedly and cause injury. Write down your dryer's model number (it's on a sticker inside the door frame or on the back) so you order the exact replacement belt for your machine. Samsung dryers come in two main configurations: vented models that exhaust to the outside, and heat pump models that recirculate air. The belt replacement process is nearly identical for both, but the parts you'll encounter inside may look slightly different. Either way, the steps below will get you there.

Key Takeaways

  • Unplug your dryer before opening it, and keep it unplugged throughout the entire repair.
  • The drum belt wraps around the drum and is held in place by the idler pulley and drum rollers; when it breaks, the drum stops turning even though the motor runs.
  • You will need to remove the front panel or rear panel depending on your model, and the exact steps vary—check your model number against Samsung's parts diagram before you start.
  • Order the belt by model number from Samsung, a parts retailer like AppliancePartsPros or PartSelect, or a local appliance parts shop.
  • If the idler pulley or drum rollers are worn or damaged while you have the dryer open, replacing them at the same time prevents a second repair soon after.

Locate your model number and order the correct belt

Open the dryer door and look for a white sticker on the inside edge of the door frame, usually on the left side. The model number starts with "DV" and is followed by numbers and sometimes letters—for example, DV22N6800HX or DVE45R6100W. Write this down or take a photo.

Go to Samsung's parts website (parts.samsung.com), enter your model number, and search for "belt" or "drum belt." You'll see the exact part number and price. Alternatively, visit AppliancePartsPros.com, PartSelect.com, or call a local appliance parts supplier with your model number. Shipping usually takes 2 to 5 business days, so order before you start the repair if you don't already have the belt on hand.

Remove the front or rear panel to access the drum

This step depends on whether your Samsung dryer is a front-load or top-load design. Most Samsung dryers are front-load, meaning the lint trap is on the front. If your lint trap is on top, you have a different model and should consult Samsung's service manual for your specific machine.

For front-load Samsung dryers, you will remove the front panel. Unplug the dryer. Open the door and remove the lint trap by pulling it straight out. Close the door. At the top of the front panel, there are usually two screws or clips holding the panel in place—look for them just above the door opening. Remove these screws with a screwdriver. Gently pull the front panel toward you and lift it away from the dryer. Set it aside in a safe place where it won't get damaged. You may see a wire or clip connecting the door latch assembly to the front panel. If so, disconnect it by pressing the tab or unclipping it before you fully remove the panel. Take a photo with your phone so you remember how to reconnect it later.

Disconnect the idler pulley and remove the old belt

With the front panel off, you can now see the drum and the components around it. The idler pulley is a small wheel that keeps tension on the belt. It's usually located on the left side of the drum, below the drum itself. The belt wraps around the drum and under the idler pulley.

The idler pulley is held in place by a spring or a bolt. If it's held by a spring, use a putty knife or flathead screwdriver to gently pry the spring off the pulley bracket. If it's held by a bolt, use a socket wrench or screwdriver to remove it. Once the idler pulley is loose, you can lift it away from the drum. Now the old belt should come free. It may be wrapped tightly around the drum, so you may need to rotate the drum slightly by hand to unwind it. Pull the belt off completely and set it aside.

Inspect the idler pulley and the drum rollers (the wheels that support the drum) for wear. If the idler pulley is cracked, has a flat spot, or doesn't spin freely, or if the drum rollers are worn smooth or cracked, replace them now while you have the dryer open. Ordering these parts takes the same time as ordering the belt, and doing both repairs together saves you from opening the dryer again in a few months.

Install the new belt and reconnect the idler pulley

Take the new belt and thread it around the drum, starting at the top and working your way around. The belt should sit in the groove that runs around the drum—it won't stay in place on its own, so guide it carefully as you wrap it. Once the belt is fully wrapped, position the idler pulley back into place and find it with the spring or bolt you removed earlier. If you removed a spring, press it back onto the pulley bracket until it clicks. If you removed a bolt, tighten it snugly but do not over-tighten, as this can strip the threads.

Spin the drum by hand a few times to make sure the belt is seated properly and the drum rotates smoothly. The belt should not slip or make noise. If it does, stop and check that the belt is fully seated in the drum groove and that the idler pulley is tight.

Reassemble the front panel and test the dryer

Reconnect any wires or clips you disconnected from the front panel, using your phone photo as a reference. Align the front panel with the dryer body and push it back into place. find it with the screws or clips you removed at the beginning. Reinsert the lint trap into its slot on the front panel.

Plug the dryer back into the wall outlet. Close the door and run a test cycle on the lowest heat setting with no clothes inside. Listen for unusual noises and watch to make sure the drum rotates smoothly. If the drum turns and the dryer heats normally, the repair is complete. If the drum does not turn or makes grinding noises, unplug the dryer when ready and check that the belt is seated correctly and the idler pulley is tight.

When to call a professional

If you open the dryer and find that the drum rollers or idler pulley are damaged, you can replace those parts yourself using the same process, but if you are not comfortable doing so, a service technician can handle all three repairs in one visit. If the drum does not turn after you install the new belt, or if you hear grinding or squealing noises that don't go away, the problem may be something other than the belt—such as a faulty motor or a broken drum bearing—and you should contact a Samsung service center or a local appliance repair shop.

Some dryers have a thermal fuse that blows if the dryer overheats, and this can prevent the drum from turning even with a new belt. A technician can test for this and replace it if needed. If you're uncertain whether the problem is the belt or something else, it's worth having a professional diagnose it before you attempt further repairs.

Frequently Asked Questions

How do I know if the belt is actually broken?

If the drum does not turn when you start a cycle but you hear the motor running, the belt is broken or has slipped off. Open the door and try to turn the drum by hand—if it won't budge, the belt is likely broken. You can also remove the front panel and look at the belt directly; a broken belt will be snapped in two or frayed.

Can I replace just the belt, or do I need to replace the idler pulley too?

You can replace just the belt if the idler pulley spins freely and shows no cracks or flat spots. However, if the pulley is worn, replacing it at the same time prevents the new belt from wearing out prematurely. Many technicians recommend replacing both together as a preventive measure.

What if I can't find the model number sticker?

Check the back of the dryer near the bottom, or look inside the door frame on both the left and right sides. If you still can't find it, call Samsung customer service with your serial number (also on a sticker somewhere on the dryer) and they can tell you the model number and direct you to the correct belt.

How long does a new belt last?

A Samsung dryer belt typically lasts 3 to 7 years depending on how often you use the dryer and whether you clean the lint trap regularly. A clogged lint trap forces the dryer to work harder and wears the belt faster, so keeping the trap clean extends the belt's life.

Is it safe to use the dryer while waiting for the new belt to arrive?

No. If the belt is broken, the drum will not turn and clothes will not dry. Running the dryer with a broken belt can overheat the motor and cause a fire. Do not use the dryer until the belt is replaced.
