A dryer belt replacement takes about an hour and costs $15 to $50 for the part

The drum belt in your dryer wraps around the drum and pulley to spin it when the motor turns on. Over time—usually two to five years depending on use—the belt wears thin, frays, or snaps. When it breaks, the drum stops turning even though you hear the motor running. Replacing it is a straightforward repair you can do yourself with basic tools: a screwdriver, a socket wrench, and the replacement belt ordered for your exact dryer model.

The belt sits inside the dryer cabinet, so you will need to remove the front or rear panel to reach it. The exact steps depend on your dryer's design, but the principle is the same: unplug the machine, open the cabinet, remove the old belt from the drum and pulley, thread the new one on, and reassemble. Most people finish in 45 minutes to an hour.

Key Takeaways

  • Always unplug the dryer before you start, and wait at least 30 minutes for the drum to cool if you have just run a cycle.
  • Order the replacement belt using your dryer's model number, which is on a sticker inside the door frame or on the back panel.
  • The belt is accessed from either the front or rear depending on your model; check your manual or search your model number online to find which.
  • The new belt threads around the drum and over the idler pulley in a specific path; take a photo of the old belt before removing it so you can match the routing.
  • If the drum does not turn smoothly after reassembly or the belt slips, the idler pulley or drum rollers may also need replacement.

Finding your dryer model number and ordering the right belt

The model number is printed on a sticker inside the dryer door frame or on the back panel near the power cord. Write it down or take a photo. Search that model number plus the word "belt" on the manufacturer's website or on appliance parts retailers like Sears Parts Direct, AppliancePartsPros, or PartSelect. The belt for a Whirlpool dryer is different from a GE dryer, and even within the same brand, different models use different belts.

When you find the part, verify it matches your model number exactly before ordering. The belt usually costs between $15 and $50. Many retailers ship within two to three business days. While you wait, unplug the dryer and leave it unplugged until you are ready to work.

Unplugging and cooling the dryer safely

Unplug the dryer from the wall outlet before you touch anything inside. If your dryer is hardwired (connected directly to the electrical panel with no plug), turn off the circuit breaker for the dryer and leave it off while you work. Wait at least 30 minutes after running a cycle so the drum cools down and you do not burn your hands.

Do not skip this step. The drum can retain heat, and the electrical components inside can cause serious injury if the machine is still powered.

Removing the front or rear panel to access the belt

Check your dryer's manual or search your model number online to find out whether the belt is accessed from the front or rear. Front-access dryers (common in newer models) require you to remove the front panel. Rear-access dryers require you to pull the dryer away from the wall and remove the rear panel.

For a front-access dryer, look for screws along the top edge of the front panel, usually hidden under a trim piece. Remove those screws, then gently pull the panel toward you. You may need to disconnect a door latch assembly—take a photo before you disconnect anything so you remember how it goes back together.

For a rear-access dryer, pull the machine away from the wall, unplug it if you have not already, and remove the screws holding the rear panel. Slide the panel off carefully.

Removing the old belt and threading on the new one

Before you touch anything, take a clear photo of how the old belt is routed around the drum and the idler pulley. The belt path matters, and this photo is your reference.

Locate the drum (the large cylinder in the center) and the idler pulley (a smaller wheel that keeps tension on the belt). Loosen the tension by hand or with a wrench, depending on your model. Slide the old belt off the drum and pulley. If the belt is broken, you may need to remove pieces.

Thread the new belt onto the drum first, then route it over the idler pulley, matching the path shown in your photo. The belt should sit flat and centered on both the drum and pulley—no twists or bunching. Tighten the idler pulley back to its original position. The belt should have slight give when you press it with your thumb; it should not be so tight that the drum is hard to turn by hand.

Reassembling the dryer and testing the repair

Reconnect any wiring you disconnected (door latch, thermal fuse, etc.) by matching your photos. Slide the front or rear panel back into place and tighten all screws. Make sure the panel sits flush and does not rattle.

Plug the dryer back in or turn the circuit breaker back on. Run the dryer on a short cycle (air dry or low heat for 10 minutes) with no clothes inside. Listen and watch: the drum should turn smoothly and quietly. If the drum does not turn, the belt may not be routed correctly or may be too loose. If you hear squeaking or the belt slips, the idler pulley may be worn and need replacement as well.

When to call a professional instead

If you open the dryer and the drum rollers (the wheels that support the drum) are visibly cracked or flat, or if the idler pulley is cracked or does not spin freely, those parts also need replacement. Replacing them requires the same disassembly, but adds another 30 to 45 minutes and another $30 to $80 in parts. Many people choose to have a technician handle multiple repairs at once.

If the drum still does not turn after you install the new belt and route it correctly, or if the belt slips when ready, stop and call a technician. Continuing to run the dryer may damage the motor or other components. A service call usually costs $100 to $200, but it is cheaper than replacing the entire dryer.

Frequently Asked Questions

How do I know if the belt is actually broken?

If the drum does not turn when you start the dryer but you hear the motor running, the belt is likely broken or slipped off. Open the dryer and look at the belt—if it is frayed, cracked, or missing pieces, it needs replacement. If the belt looks intact but is very loose, it may have slipped off the pulley.

Can I reuse the old belt if I put it back on?

No. If the belt broke or slipped, it has lost its grip and elasticity. Reusing it will fail again within days or weeks. Always install a new belt.

What if I cannot find my dryer model number?

Check inside the door frame, on the back panel, under the lint trap, or on the side walls inside the drum. If you still cannot find it, take a photo of your dryer and bring it to an appliance parts store—staff can often identify the model by sight or help you search the manufacturer's website.

Do I need to replace the idler pulley at the same time as the belt?

Not always. If the pulley spins freely and has no visible cracks, it can stay. However, if it is cracked, does not spin, or if the new belt slips when ready after installation, the pulley needs replacement too. Many technicians replace both at once to avoid a second service call.

How long does a new belt last?

A new belt typically lasts two to five years depending on how often you use the dryer and whether other parts like the idler pulley or drum rollers are in good condition. If those parts are worn, they will wear out the new belt faster.
