What You Need to Know Before You Start

A clothes dryer belt is a rubber loop that wraps around the drum and turns it when the motor runs. When it wears out or snaps, the drum stops spinning even though you can hear the motor running. Replacing it is a job most homeowners can do in 30 to 45 minutes with basic tools — no special skills required, though you do need to be comfortable working inside an appliance.

The belt sits inside the dryer cabinet, underneath the drum. To reach it, you'll remove the front or rear panel (depending on your dryer model), slide the drum out partway, and swap the old belt for a new one. The hardest part is usually getting the cabinet open without breaking the clips that hold it together.

Before you begin, unplug the dryer from the wall outlet. This is not optional — the motor can start unexpectedly and cause serious injury. If your dryer is gas-powered, also turn off the gas supply at the valve behind the unit.

Key Takeaways

  • You must unplug the dryer and, for gas models, turn off the gas supply before opening the cabinet.
  • The belt is a rubber loop under the drum; you access it by removing either the front or rear panel and sliding the drum forward or backward.
  • You need the correct belt model for your dryer — check the model number on the back or inside the door frame and order the exact replacement.
  • The entire job takes 30 to 45 minutes and requires only a screwdriver, a putty knife or flat tool, and possibly a socket wrench.
  • If the drum rollers or idler pulley are also worn, replacing them at the same time prevents a second repair soon after.

Find Your Dryer Model Number and Order the Right Belt

Dryer belts are not universal. A belt for a Whirlpool will not fit a GE, and even within the same brand, different models use different belt widths and lengths. Ordering the wrong one means a wasted trip and another day without a dryer.

Locate your dryer's model number — it is usually printed on a sticker inside the door frame, on the back panel, or on the side wall inside the cabinet. Write down the full model number and search for "[your brand] [model number] dryer belt" on the parts website for your manufacturer, or on a general appliance parts site like Repair Clinic or PartSelect. These sites will show you the exact belt and often the idler pulley and drum rollers as well, so you can see what else might need replacing.

Order the belt before you start the repair. If you open the dryer and find the idler pulley is also cracked or the drum rollers are worn flat, you will want to replace those too — they often fail around the same time as the belt. Having all three parts on hand means you do the job once instead of twice.

Remove the Dryer Cabinet and Access the Belt

Unplug the dryer. If it is gas, turn the gas valve to the off position. Wait a few minutes for any residual heat to dissipate.

Most dryers open from the front — you remove the front panel to reach the drum. Some older or commercial models open from the back. Check your manual or look at the seams: if you see a line of screws or clips running horizontally across the front below the door, it is a front-access dryer.

For a front-access dryer, open the door and look for two screws at the top corners of the opening, just inside the frame. Remove these screws. Then use a putty knife or flat screwdriver to gently pry the bottom edge of the front panel away from the cabinet — there are usually plastic clips holding it in place, and they will pop free with light pressure. Once the bottom is loose, lift the panel up and away. Set it aside where it will not fall or get stepped on.

For a rear-access dryer, remove the screws holding the rear panel to the cabinet and lift it away. You will now see the back of the drum and the belt wrapped around it.

Remove the Old Belt and Install the New One

On a front-access dryer, you will see the drum sitting in the cabinet. The belt is wrapped around the outside of the drum and also around the idler pulley (a small wheel that keeps tension on the belt) and the drive pulley (which is connected to the motor). To access the belt, you need to slide the drum forward slightly — usually just two to three inches is enough.

Look for the idler pulley, which is a spring-loaded wheel usually located near the bottom front of the cabinet. You will see a spring attached to it. Gently pull the idler pulley away from the drum to release the tension on the belt. This is easier if you have a helper, but you can also use a clamp or a block of wood to hold the pulley in place while you work.

With the tension released, slide the old belt off the drum, the idler pulley, and the drive pulley. It will come free in one piece. Discard it.

Take the new belt and thread it onto the drive pulley first (the pulley connected to the motor). Then wrap it around the drum, and finally loop it around the idler pulley. The belt should sit snugly in the grooves of each pulley. Release the idler pulley and let the spring pull it back into place — the belt should now be under tension.

Slide the drum back into its original position. The belt should not slip or bunch up. If it does, pull the drum forward again and adjust the belt position on the pulleys.

Reassemble the Dryer and Test It

Slide the front panel back into place, aligning the top edge first and then pressing the bottom edge down until the clips snap into place. Install the two screws at the top corners of the door opening. For a rear-access dryer, straightforward screw the rear panel back on.

Plug the dryer back in. If it is a gas dryer, turn the gas valve back to the on position and listen for the igniter to click when you turn on the heat.

Run the dryer on a short cycle with no clothes inside. Listen for any unusual noises — a squeaking sound usually means the idler pulley is worn and should be replaced next time. The drum should spin smoothly and stop when you open the door. If the drum does not spin at all, the belt may not be seated correctly on the pulleys; unplug the dryer and check the belt position again.

When to Call a Professional

If you open the cabinet and find that the idler pulley is cracked, the drum rollers are worn flat, or the drive pulley is damaged, you can replace these parts yourself using the same process — they are held in place with screws or clips. However, if the motor is not running at all, or if you hear a grinding noise from inside the motor housing, the motor itself may be damaged and will need professional service.

If you are uncomfortable working inside the dryer cabinet, or if you do not have a helper and cannot safely manage the idler pulley tension on your own, a repair technician can do this job for $150 to $300 including the part. It is worth paying for peace of mind if you are not confident.

Frequently Asked Questions

How do I know if the belt is actually broken?

If the drum does not turn but you can hear the motor running, the belt is either broken or has slipped off the pulleys. Open the dryer and look at the belt — if it is frayed, cracked, or missing entirely, it is broken. If it is still there but loose, it may have slipped and can sometimes be repositioned without replacement.

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

You can replace just the belt if it is the only thing that is damaged. However, if the idler pulley is also worn (you will see cracks or a flat spot on the wheel), replacing both at the same time prevents the new belt from wearing out quickly. Check the pulley while you have the cabinet open.

What if the belt keeps slipping off after I install it?

The belt is slipping because the idler pulley is not holding tension correctly. This usually means the pulley is worn or the spring is broken. You will need to replace the idler pulley. Do not run the dryer with a slipping belt — it will overheat and damage the drum.

How long does a dryer belt usually last?

A dryer belt typically lasts five to seven years with normal use. If you dry heavy loads daily, it may wear out sooner. Once it breaks, it cannot be repaired — it must be replaced.

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 the clothes will not dry. The motor will run and generate heat, which can damage the heating element or create a fire hazard. Do not use the dryer until the belt is replaced.
