What You Need to Know Before You Start
A dryer belt wraps around the drum and turns it when the motor runs. When the belt breaks or frays, the drum stops spinning even though you hear the motor running. You can replace it yourself in about an hour with basic tools — a screwdriver, a socket wrench, and needle-nose pliers — without calling a technician.
The hardest part is not the replacement itself but getting to the belt. On most dryers, you have to remove the front panel or the rear panel to reach it. Which one depends on your model. Check your dryer's manual or search the model number online to find out which direction your belt runs and where it sits. This matters because some belts wrap around a pulley at the bottom, others around a drum roller at the top, and the order you remove parts changes based on that.
Before you start, unplug the dryer from the wall outlet. Do not skip this step. A dryer motor can turn on unexpectedly while you are working inside, and your fingers can get caught.
Key Takeaways
- Unplug the dryer completely before opening it — the motor can turn on while you work inside.
- Check your dryer's manual or model number to learn whether you remove the front or rear panel first.
- The belt usually costs between $30 and $60 and takes about an hour to replace once you have the panel off.
- When you reinstall the belt, make sure it sits flat in the groove of the pulley or roller — a twisted belt will break again quickly.
- If the drum rollers or idler pulley feel rough or damaged while you have the panel open, replace those too, because they wear out at the same time as the belt.
Locate the Belt and Decide Which Panel to Remove
Open your dryer door and look at the seam where the front panel meets the cabinet. If you see a gap or a lip that the panel sits under, you will remove the front panel. If the front panel looks flush and sealed, you will remove the rear panel instead. The manual for your model will confirm this, but the visual check usually works.
Once you know which panel comes off, look up the belt routing diagram for your model online or in the manual. Take a photo of it with your phone. The diagram shows you how the belt wraps around the drum, idler pulley, and motor pulley. You will need this photo when you thread the new belt back in, because getting the path wrong means the drum will not turn.
Order your replacement belt before you start. Belts are model-specific, so search "[your dryer model number] belt" and buy the exact part. Having it on hand means you are not stuck with an open dryer waiting for delivery.
Remove the Front or Rear Panel
If you are removing the front panel: Open the dryer door fully. Look along the top edge of the front panel, inside the door opening. You will see two or three screws holding the panel to the cabinet. Remove them with a screwdriver. Then look at the bottom corners of the front panel — there are usually two clips that hook into slots on the cabinet. Gently pull the bottom of the panel toward you, then lift it up and away. Set it aside where it will not get scratched.
If you are removing the rear panel: Unscrew the four corner bolts that hold the rear panel to the cabinet. Use a socket wrench that fits your dryer's bolt size — usually 1/4 inch. Lift the panel straight up and set it down flat so you do not bend it.
Once the panel is off, you will see the drum, the belt wrapped around it, and the pulleys underneath or beside it. The belt will look like a dark rubber loop, often frayed or broken at this point. Do not touch the heating element or any electrical connections — they are not part of this job.
Remove the Old Belt and Pulleys
Before you touch the belt, take a second photo of how it sits on the pulleys and drum. You will reference this when you install the new one.
Locate the idler pulley — a small wheel that keeps tension on the belt. It is usually near the bottom of the drum or to one side. The idler pulley has a spring attached to it. Use needle-nose pliers to unhook the spring from its anchor point on the cabinet. The spring will pull back, and the tension on the belt will release. Now you can slide the old belt off the drum and pulleys by hand.
While you have the panel open, spin the idler pulley and the drum rollers (the wheels that support the drum) by hand. They should spin freely and quietly. If either one feels rough, gritty, or does not spin smoothly, note it. These parts wear out at the same time as the belt, and replacing them now saves you from opening the dryer again in a few months.
If you need to replace the idler pulley or rollers, remove them now by unbolting them from the cabinet. Keep the bolts in a small cup so you do not lose them. Install the new parts before you put the belt on.
Thread the New Belt Onto the Drum and Pulleys
Lay the new belt on a flat surface and look at it. One side is smooth, the other has grooves or ribs. The grooved side faces the pulleys. The smooth side faces the drum. This matters — a belt installed backward will slip and break.
Starting at the top of the drum, drape the belt over the drum so it hangs down on both sides. The belt should sit in the center of the drum, not bunched to one side. Now thread the belt under and around the pulleys in the exact order shown in your routing diagram. Go slowly. If you skip a pulley or thread it in the wrong direction, the drum will not turn when you plug the dryer back in.
Once the belt is threaded, use your fingers to make sure it sits flat in the groove of each pulley. A twisted belt will slip and wear out fast. The belt should look like a smooth loop, not kinked or folded anywhere.
Reattach the Idler Pulley Spring and Test the Drum
The idler pulley spring is what keeps the belt tight. Use needle-nose pliers to hook the spring back onto its anchor point on the cabinet. You may need to pull the spring slightly to reach the anchor — this is normal. The spring should be taut but not so tight that you cannot move it by hand.
Spin the drum by hand. It should turn smoothly and easily. If it feels stiff or catches, the belt is not threaded correctly or the spring is too tight. Stop and check the routing diagram again. Do not plug the dryer in until the drum spins freely.
Once the drum spins smoothly, reinstall the front or rear panel by reversing the steps you used to remove it. Tighten all screws and bolts firmly but do not over-tighten — you can crack the plastic or strip the threads.
Plug In the Dryer and Run a Test Cycle
Plug the dryer back into the wall outlet. Close the door and run the dryer on the air-dry or low-heat setting for 5 to 10 minutes. Listen and watch. The drum should turn steadily. You should not hear squeaking, grinding, or the belt slipping. If the drum does not turn or you hear noise, unplug the dryer when ready and recheck the belt routing.
If everything sounds and feels normal, run a full drying cycle with a small load of damp clothes. The belt should hold up without slipping. A new belt usually feels tighter than the old one, so do not be alarmed if the dryer sounds slightly different for the first few uses.
Frequently Asked Questions
How do I know if my dryer belt is actually broken?
If the drum does not turn when you run the dryer but you hear the motor running, the belt is broken or slipped off. Open the dryer door and try to spin the drum by hand. If it will not budge, the belt is either broken or the idler pulley spring is too tight. If the drum spins easily by hand but not when the dryer is on, the belt has slipped off the pulleys.
Can I replace just the belt, or do I have to replace the rollers too?
You can replace just the belt if the rollers spin smoothly and quietly. But if they feel rough or gritty when you spin them by hand, replace them at the same time. Worn rollers will damage the new belt quickly, and you will be back inside the dryer in a few months.
What if the belt keeps slipping even after I install the new one?
The idler pulley spring is probably too loose. Check that the spring is hooked securely onto its anchor point and that it is pulling the idler pulley toward the belt. If the spring looks damaged or stretched, replace it. A weak spring cannot hold the belt tight enough to grip the pulleys.
Do I need to replace the drum seal or felt while I have the panel open?
The drum seal and felt are separate from the belt and do not need to be replaced unless they are visibly torn or the drum is making a loud scraping noise. If you see damage, you can replace them while the panel is open, but it is not required for the belt replacement.
How long does a new dryer belt usually last?
A new belt typically lasts three to five years with normal use. If you replaced worn rollers or the idler pulley at the same time, the belt may last longer because it is not fighting against damaged parts.
