What You Need to Know Before You Start
A dryer belt is the rubber loop that spins the drum and dries your clothes. When it breaks or wears thin, your drum stops turning even though the motor runs. You will hear the motor humming but see the drum sitting still. Replacing the belt yourself takes about 30 minutes and costs $15 to $40 for the part, compared to $200 to $300 for a service call.
The belt wraps around the drum and connects to a pulley and idler wheel. When the belt frays, snaps, or loses grip, the whole system fails. The good news: this is one of the most straightforward dryer repairs, and you do not need special tools beyond a screwdriver and a socket wrench.
Before you begin, unplug the dryer from the wall outlet. This is not optional. Even though you will not be working near the heating element, the motor can still turn on and injure your hands. Leave it unplugged for the entire job.
Key Takeaways
- Always unplug the dryer before opening it, and keep it unplugged for the entire repair.
- The belt wraps around the drum, idler wheel, and pulley—all three must be in good condition for the new belt to work.
- You will need to remove the front or rear panel depending on your dryer model, which takes 5 to 10 minutes.
- The new belt costs $15 to $40 and should be the exact model number match for your dryer.
- If the idler wheel or pulley is cracked or worn, replace it at the same time to avoid another breakdown in a few months.
Find Your Dryer Model Number and Order the Right Belt
The model number is on a sticker inside the door frame or on the back panel. Write it down exactly as it appears. Search online for "[your model number] dryer belt" and order the replacement. Do not guess at the belt size—a belt that is too loose will slip, and one that is too tight will strain the motor.
While you wait for the belt to arrive, inspect the idler wheel and pulley through the front or rear access panel. The idler wheel looks like a small wheel with a spring attached; the pulley is a grooved wheel the belt rides on. If either is cracked, worn flat on one side, or makes noise when you spin it by hand, order a replacement for that part too. Replacing them now costs $10 to $30 extra but saves you from taking the dryer apart again in three months.
Remove the Front or Rear Panel
Most dryers have either a front-loading or rear-loading design. Check your manual or look at the access panel—if you see screws on the front, you will remove the front panel. If the screws are on the back, you will remove the rear panel. Front-panel dryers are more common in newer models.
For a front-panel dryer, locate the screws along the bottom edge of the front panel. Remove them with a Phillips or flathead screwdriver—usually four to six screws. Gently pull the panel toward you and set it aside. You will now see the drum, belt, idler wheel, and pulley.
For a rear-panel dryer, unscrew the rear access panel the same way. You may need to remove the lint trap housing first. Once the panel is off, you will see the belt wrapped around the back of the drum.
Remove the Old Belt
The belt wraps around the drum in a figure-eight or spiral pattern, depending on your model. Look at how it sits before you touch anything—take a photo with your phone if it helps you remember the path. The belt also wraps around the idler wheel and pulley.
To remove the belt, you must first release tension on the idler wheel. The idler wheel has a spring attached that keeps the belt tight. Push the idler wheel away from the drum to loosen the belt, then slide the belt off the drum, pulley, and idler wheel. The old belt will come free in your hand.
Inspect the idler wheel and pulley while they are exposed. Spin the pulley by hand—it should turn smoothly and quietly. Spin the idler wheel—it should also turn freely. If either one is cracked, flat-spotted, or makes a grinding sound, replace it now before you install the new belt.
Install the New Belt
Lay the new belt on a flat surface and look at its shape. Most belts have a slight curve or twist. Thread the belt around the drum first, following the same path the old belt took. If you took a photo, use it as a guide. The belt should sit in the grooves on the drum, not on top of it.
Once the belt is around the drum, guide it around the pulley. The pulley sits at the bottom of the drum and the belt should nestle into its grooves. Then wrap the belt around the idler wheel. The idler wheel will spring back toward the drum as you do this, creating tension on the belt. This tension is what keeps the belt from slipping.
Spin the drum by hand to make sure the belt moves smoothly and does not slip or bunch up. If it does, stop and reposition the belt. The belt should be centered on the drum and pulley, not riding on the edge.
Reassemble the Dryer and Test
Once the belt is seated correctly, replace the front or rear panel and tighten all screws. Do not over-tighten—snug is enough. Plug the dryer back into the wall outlet.
Run the dryer on a short cycle with no clothes inside. Listen for grinding, squeaking, or thumping sounds. The drum should spin smoothly and quietly. If you hear noise, unplug the dryer when ready and check that the belt is seated correctly on the pulley and idler wheel.
If the drum spins smoothly and silently, the repair is complete. Run a full cycle with a small load of damp towels to confirm the dryer heats and dries normally. The belt should not slip or make noise under load.
Common Mistakes to Avoid
The most common mistake is threading the belt in the wrong path around the drum. The belt must follow the grooves—if it rides on the flat surface between grooves, it will slip and wear out quickly. Take time to match the old belt's path before you install the new one.
Another mistake is not releasing the idler wheel tension before removing the old belt. If you try to force the belt off without moving the idler wheel, you may damage the wheel or pulley. Always push the idler wheel away first.
A third mistake is replacing only the belt and ignoring a worn idler wheel or pulley. If the idler wheel is flat-spotted or the pulley is cracked, the new belt will wear out in weeks. Inspect both parts and replace them if they show damage.
Finally, do not over-tighten the panel screws when you reassemble. Over-tightening can crack the plastic housing and cause leaks or electrical problems. Tighten until snug, then stop.
Frequently Asked Questions
How do I know if the belt is the problem and not something else?
If the drum does not turn but the motor runs and you hear humming, the belt is almost certainly broken or slipped off. If the dryer does not heat, the problem is the heating element or thermostat, not the belt. If the drum turns but makes grinding or squeaking sounds, the idler wheel or pulley may be failing.
Can I use a belt from a different dryer model?
No. Belts vary in length, width, and thickness by model. Using the wrong belt will either slip off or be too tight and strain the motor. Always match the model number exactly.
What if the idler wheel or pulley is damaged—do I have to replace it?
If the idler wheel is cracked or the pulley is flat-spotted, yes, replace it. A damaged wheel or pulley will wear out the new belt in a few weeks. Replacing both at the same time costs less in parts and labor than doing the job twice.
How long does a new dryer belt last?
A new belt typically lasts 3 to 5 years with normal use. Lint buildup and high heat can shorten its life. Cleaning the lint trap after every load and vacuuming the vent duct once a year helps the belt last longer.
Do I need to replace the felt seal around the drum at the same time?
The felt seal is a separate part that sits between the drum and housing. If it is torn or worn, lint will escape and clog the vent. You can replace it at the same time as the belt, but it is not required. If lint is escaping around the drum, replace the seal.
