What You Need to Know Before Starting
A dryer belt wraps around the drum and spins it when the motor turns. When the belt breaks or frays, the drum stops turning even though you hear the motor running. Replacing it yourself takes about 30 minutes and costs $15 to $40 for the belt alone—far less than a service call.
Before you begin, unplug the dryer from the wall outlet. This is not optional. A dryer can still deliver a serious shock even when it is off, and the drum can spin unexpectedly if power reaches it. Leave it unplugged for at least five minutes so any residual charge drains from the capacitor inside.
You will need a Phillips head screwdriver, a flathead screwdriver or putty knife, and the replacement belt for your exact dryer model. Find your model number on a sticker inside the door frame or on the back of the unit, then order the correct belt online or from an appliance parts supplier. Using the wrong belt will cause the drum to slip or wear out quickly.
Key Takeaways
- Unplug the dryer completely and wait five minutes before opening it, because the machine can shock you even when powered off.
- You must remove the front panel or top panel depending on your dryer model—check your manual or search your model number online to see which applies to yours.
- The old belt slides off the drum and idler pulley; the new belt goes on in the same path, routed around the drum first, then under the idler.
- The idler pulley often wears out at the same time as the belt, so inspect it for cracks or a loose center bolt before reassembling.
- Reassemble in reverse order, plug in the dryer, and run it empty for two minutes to confirm the drum spins smoothly before drying clothes.
Locate Your Model Number and Order the Correct Belt
Open the dryer door and look for a white or silver sticker on the inside of the door frame, usually on the left or right side. Write down the full model number—it typically starts with letters like GE, LG, Whirlpool, or Samsung followed by numbers. If you cannot find it on the door frame, check the back panel of the dryer or the top edge under the lid.
Search your model number plus "dryer belt" on a parts website like PartSelect, AppliancePartsPros, or your manufacturer's official site. You will see the exact belt that fits your machine. Order it now so you have it on hand before you start taking the dryer apart. While you wait for delivery, you can watch a video of your specific model to see whether the front or top panel comes off first—this varies by brand.
Remove the Front or Top Panel
Most dryers fall into two categories: those where you remove the front panel (Whirlpool, Maytag, Kenmore) and those where you remove the top panel (GE, LG, Samsung). Check your manual or search "[your model number] belt replacement" on YouTube to see which applies to yours.
For front-panel models: Look along the bottom edge of the front panel for two or three Phillips screws. Remove them. Then look for clips along the top edge—slide a flathead screwdriver or putty knife gently under the top corners to pop the panel free. It will hinge down toward you. Disconnect the door latch wire if there is one (a small wire that runs from the panel to the door switch), then set the panel aside.
For top-panel models: Open the door and look for two Phillips screws on the inside of the door frame, one on each side. Remove them. Then lift the top panel up and toward you—it will tilt back and rest against the wall behind the dryer. You do not need to disconnect anything; just be careful not to strain any wires.
Remove the Old Belt and Inspect the Idler Pulley
Once the panel is open, you will see the drum (a large cylinder) and the idler pulley (a small wheel underneath or to the side of the drum). The belt wraps around both. Reach in and lift the idler pulley arm slightly to release tension on the belt, then slide the old belt off the drum and idler. Set it aside.
Before you install the new belt, inspect the idler pulley. Spin it with your finger—it should turn freely and smoothly. If it is cracked, does not spin, or wobbles side to side, it needs replacement too. A worn idler pulley will wear out your new belt in a few months. If you see damage, order an idler pulley for your model and replace it now using the same process: remove the bolt holding it in place, slide the old one off, and slide the new one on.
Also check the drum felt seal (a felt ring around the front of the drum where it enters the housing). If it is torn or missing, the belt will wear faster. If it looks damaged, note it for a future repair, but you can operate the dryer safely for now.
Install the New Belt
Take the new belt and route it around the drum first, starting at the top. The belt should sit in the groove that runs around the drum's circumference. Feed it all the way around, keeping it centered in that groove.
Once the belt is seated around the drum, route it under the idler pulley. The idler pulley arm will hold tension on the belt automatically once you release it. The belt should now form a loop: around the drum, under the idler, and back to where it started. Check that it is not twisted and sits flat in the drum groove.
If your dryer has a felt seal or glides around the drum, make sure the belt does not pinch them. Spin the drum by hand a few times to confirm the belt moves smoothly without catching.
Reassemble the Dryer
If you replaced the idler pulley, reinstall its mounting bolt and tighten it firmly with your screwdriver—it should not wobble. Then reverse the panel removal process.
For front-panel models: Reconnect the door latch wire if you disconnected it. Align the top corners of the panel with the slots in the housing, then press down firmly until you hear or feel the clips snap into place. Install the Phillips screws along the bottom edge and tighten them snugly—do not over-tighten, as you can crack the plastic.
For top-panel models: Lower the top panel back down and align the screw holes on the inside of the door frame. Install and tighten the two Phillips screws.
Close the dryer door and plug the unit back into the wall outlet.
Test the Dryer Before Using It
Set the dryer to air dry or the lowest heat setting and run it for two minutes with no clothes inside. Listen for unusual noises and watch through the door to confirm the drum spins smoothly. If the drum does not turn, stop when ready, unplug the dryer, and check that the belt is routed correctly around the drum and under the idler.
If the drum spins normally, stop the dryer, let it cool for a minute, and run a normal load. The belt may smell slightly as it settles into place—this is normal and will fade after one or two loads.
Common Mistakes to Avoid
The most common error is routing the belt incorrectly. The belt must go around the drum first, then under the idler pulley. If you route it the other way, the drum will not turn. Double-check the path before you close the panel.
Another mistake is forgetting to unplug the dryer. Even with the door open and the power off, the capacitor inside can hold a charge and deliver a shock. Always unplug it and wait five minutes.
Do not over-tighten the screws when reassembling. Plastic panels crack easily, and you will have a bigger repair on your hands. Tighten until snug, then stop.
If the belt breaks again within a few months, the idler pulley is likely worn and needs replacement. A worn idler forces the belt to work harder and fail sooner. Replacing both at the same time prevents this cycle.
Frequently Asked Questions
How do I know if my dryer belt is actually broken?
If the drum does not turn when you start the dryer but you hear the motor running, the belt is broken or slipped off. If the dryer heats but the drum does not spin, the belt is the problem. A broken belt may also make a squeaking or grinding noise before it snaps completely.
Can I use a belt from a different dryer model?
No. Belts vary in length, width, and the shape of their ends. Using the wrong belt will cause the drum to slip, overheat, or not turn at all. Always order the belt for your exact model number.
What if the idler pulley is worn but I do not replace it?
The new belt will wear out much faster—often within a few months. The worn idler does not hold proper tension, so the belt slips and heats up. Replacing both at the same time costs a little more upfront but saves you from doing this job again soon.
Is it safe to run the dryer right after I install the new belt?
Run it empty for two minutes first to confirm the drum spins smoothly and there are no unusual noises. If everything sounds normal, you can dry clothes on the next load. The belt may smell slightly as it settles—this is normal.
Do I need to replace the felt seal while I have the dryer open?
Not unless it is torn or missing. If it looks intact, leave it alone. A damaged seal will shorten the life of your next belt, but the dryer is safe to use. You can replace the seal later if needed.
