A dryer belt replacement takes about an hour and costs $15 to $50 in parts

When your dryer stops tumbling but the motor still runs, the belt has usually snapped or worn through. You can replace it yourself with basic tools — a screwdriver, a putty knife or flathead screwdriver for prying, and sometimes a socket wrench depending on your model. The belt itself costs $15 to $50 new, and the job involves removing the front or rear panel, sliding out the drum, and threading the new belt around the drum and idler pulley.

Most dryers follow the same sequence, though the exact steps vary by brand. Gas dryers and electric dryers use the same belt replacement process; the difference is only in how you handle the gas line if you need to move the unit. If you are not comfortable working inside an appliance or your dryer is still under warranty, a service call runs $150 to $300 in labor alone.

Key Takeaways

  • Unplug the dryer completely before opening it, and let it cool for at least 30 minutes if it has been running.
  • Most dryers require you to remove the front panel first, then lift out the drum to access the belt underneath.
  • The new belt threads around the drum and over the idler pulley, and the idler pulley itself often needs replacing at the same time.
  • After reassembly, run the dryer empty for 5 to 10 minutes to confirm the drum turns smoothly before drying clothes.

Gather your tools and the correct replacement belt

Before you start, order the right belt for your dryer model. The belt number is printed on the old belt itself, or you can find it in your owner's manual or by searching your dryer's model number online. Belts are not universal — a belt for a Whirlpool will not fit a Maytag, and a belt for a 27-inch dryer will not work in a 29-inch model.

You will also need a Phillips or flathead screwdriver (check your manual for which), a putty knife or old butter knife for prying panels, and possibly a socket wrench or nut driver if your model uses bolts instead of screws. Many dryers also have a thermal fuse that blows when the dryer overheats; if your dryer stopped heating as well as tumbling, the fuse may have blown and should be replaced at the same time. A thermal fuse costs $10 to $20 and takes 10 extra minutes to swap.

Disconnect the dryer and remove the front panel

Unplug the dryer from the wall outlet. If it is a gas dryer, you do not need to disconnect the gas line for a belt replacement — just make sure the unit is unplugged. Wait at least 30 minutes for the drum and heating element to cool, especially if the dryer was running recently.

Most dryers have the front panel held on by screws along the bottom edge and sometimes along the top. Open the dryer door and look underneath the lip where the door closes; you will usually see two or three screws there. Remove them, then gently pull the front panel toward you. It may take some wiggling. Some models have clips instead of screws — if the panel does not budge, check the sides and top for release tabs or clips before forcing it.

Once the front panel is off, you will see the drum sitting inside. The drum is held in place by a bearing or felt seal at the back and a roller or glide at the front. You do not need to remove these yet — first, you need to see the belt, which runs underneath the drum.

Lift the drum and remove the old belt

Reach into the dryer and lift the front of the drum upward. It should lift out of the front rollers or glides. Tilt it back slightly and pull it toward you. The drum may be heavy and awkward; take your time and do not force it. Once it is out, you will see the belt wrapped around the back of the drum and looped over the idler pulley on the left side of the cabinet.

Slide the old belt off the drum and idler pulley. While you have the drum out, inspect the idler pulley — it should spin freely when you flick it with your finger. If it does not spin, or if it is cracked or worn flat on one side, replace it now. An idler pulley costs $20 to $40 and takes 5 minutes to swap; doing it now saves you from opening the dryer again in a few months.

Also check the felt seal or bearing at the back of the drum. If it is torn or worn away, it should be replaced, though this is a more involved job. If the seal looks intact, you can proceed with just the belt.

Install the new belt and idler pulley

If you are replacing the idler pulley, remove the bolt or screw holding it in place and slide the old one off. Install the new pulley the same way, making sure it sits flush against the bracket. The pulley should spin freely by hand.

Thread the new belt around the drum, starting at the top center and working it around the back. The belt should sit in the groove that runs around the drum — it will not stay centered on its own, so guide it as you work. Once the belt is wrapped around the drum, loop it over the idler pulley on the left side. The idler pulley should be positioned so the belt sits on top of it and pulls the pulley slightly toward the drum.

Double-check that the belt is seated in the drum groove all the way around and is not twisted. A twisted belt will wear quickly and may slip off the pulley.

Reinstall the drum and front panel

Lift the drum and guide it back into the dryer, tilting it slightly so the front edge sits on the front rollers or glides. Lower it gently until it is centered and level. The drum should sit about 1/4 inch back from the front opening — if it is too far forward or too far back, the door will not close properly.

Slide the front panel back into place and secure it with the screws you removed earlier. Make sure all screws are tight, but do not over-tighten them — you can crack the plastic. Close the dryer door and plug the unit back in.

Test the dryer before using it normally

Run the dryer on air-dry or low heat for 5 to 10 minutes with nothing inside. Listen for any unusual noises — squeaking, grinding, or thumping usually means the belt is not seated correctly or the drum is not centered. If you hear noise, unplug the dryer, remove the front panel again, and check that the belt is in the groove and the drum is level.

If the drum turns smoothly and quietly, the belt is installed correctly. You can now dry clothes normally. The new belt will need a few loads to settle in; it may feel slightly stiff at first, but this is normal.

Frequently Asked Questions

Can I replace just the belt, or do I have 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 now costs $20 to $40 and takes 5 minutes — waiting until it fails means opening the dryer again soon. Many people replace both at once to avoid a second repair.

What if the drum does not turn after I put the belt on?

The belt is probably twisted or not seated in the drum groove. Unplug the dryer, remove the front panel, and check that the belt runs straight around the drum without any twists. Also confirm the idler pulley is positioned correctly and the belt is looped over it, not under it.

How long does a new dryer belt usually last?

A dryer belt typically lasts 3 to 5 years with normal use. Belts wear faster if the dryer runs frequently or if the idler pulley is worn and puts extra stress on the belt. Replacing the idler pulley when it wears can extend the life of the new belt.

Is it safe to run the dryer if the belt is making noise?

A squeaking or squealing belt usually means it is slipping on the pulley, often because the idler pulley is worn. Running the dryer this way can damage the belt further and overheat the motor. It is safer to replace the belt and idler pulley before the belt breaks completely.

Do I need to replace the thermal fuse when I replace the belt?

Only if the dryer stopped heating as well as tumbling. If the dryer was still heating but just not tumbling, the thermal fuse is fine. If you are unsure, a thermal fuse costs $10 to $20 and takes 10 minutes to replace, so many people do it while they have the dryer open.
