A dryer that runs but does not tumble almost always has a broken belt, and learning how to replace a dryer belt yourself saves $150 to $250 in appliance repair bills. The belt itself costs $5 to $20, and the job takes 30 to 60 minutes with basic hand tools. This is one of the most accessible appliance repairs a homeowner can tackle, and it works the same way across most major brands including Whirlpool, Maytag, Samsung, LG, and GE.
Signs Your Dryer Belt Is Broken
The most obvious symptom is a dryer that heats and runs but the drum sits motionless. You might hear the motor humming without any tumbling sound. Some dryers with a broken belt will not start at all because they have a belt-switch safety feature that prevents the motor from running when the belt is absent.
Before the belt snaps completely, it often gives warning signs. A thumping or squealing noise during operation indicates a fraying or stretched belt slipping on the drum. If you open the dryer door and the drum spins freely with almost no resistance when you push it by hand, the belt has already broken. A properly belted drum has noticeable resistance because the belt wraps around the motor pulley and idler assembly.
Finding the Right Replacement Belt
Dryer belts are not universal. You need the correct length, width, and rib count for your specific model. Locate your dryer’s model number on the tag inside the door frame or on the back panel. It looks something like MEDB765FW or DLEX7250W. Search that model number on parts retailers like RepairClinic.com, PartSelect.com, or Amazon to find the exact belt.
- Whirlpool/Maytag/Kenmore (most models): 341241 or equivalent, 92-1/4 inch, 4 ribs
- Samsung: 6602-001655, 91-1/2 inch, 5 ribs
- LG: 4400EL2001A, 79-1/8 inch, 4 ribs
- GE: WE12M29, 89-1/2 inch, 4 ribs
Order the belt before disassembling anything. Having the part in hand means you finish the repair in one session instead of leaving a torn-apart dryer sitting in your laundry room for days.
Tools You Need
This repair requires minimal tools. A 1/4-inch nut driver, a Phillips screwdriver, a flat-head screwdriver or putty knife, and a smartphone for reference photos cover nearly every dryer model. No special appliance tools are necessary.
Unplug the dryer from the wall outlet before starting. If it is a gas dryer, also turn off the gas supply valve behind the unit. Never work on a plugged-in appliance, even if you are only accessing mechanical components. Pull the dryer away from the wall far enough to work comfortably behind and beside it.
Accessing the Drum — Top-Access Dryers
Most Whirlpool, Maytag, and Kenmore dryers use a top-access design. Insert a putty knife into the seam between the top panel and the front panel, about 2 inches from each corner. Press inward to release the spring clips, then lift the top panel and prop it up like a car hood. Take a photo of the belt routing before removing anything.
Disconnect the door switch wiring harness, then remove the screws holding the front panel — typically two at the top corners. Lift the front panel off the two bottom support tabs and set it aside. The drum is now fully exposed. Reach underneath the drum, release tension on the idler pulley by pushing it toward the motor, and slip the old belt off. If the belt is already broken, pull the remnants off the drum and out of the pulley assembly.
Accessing the Drum — Front-Access Dryers
Samsung, LG, and some GE models use a front-access design. Remove the screws securing the top panel (usually two at the rear), slide the top panel toward the back, and lift it off. Remove the screws holding the front panel and disconnect the door switch connector. The front panel lifts off to expose the drum.
On Samsung dryers, the front panel is heavy because it includes the entire door assembly. Support it as you remove the last screws to prevent it from falling forward. LG models have a similar layout but often include a lint duct housing attached to the front panel that must be removed first. Photograph each step so you can reverse the process confidently during reassembly.
Installing the New Belt
Loop the new belt around the drum with the ribbed side facing the drum surface and the flat, smooth side facing outward. Position the belt in the wear track — the slightly polished band on the drum’s exterior where the old belt sat. The belt wraps around the full circumference of the drum with the seam at the bottom.
Reach under the drum and thread the belt through the idler pulley and around the motor pulley in a zigzag pattern. On most models, the belt wraps under the idler pulley and then around the motor pulley in a Z or S configuration. Your reference photo from earlier shows the exact routing. If you did not get a photo, the manufacturer’s parts diagram (available free on RepairClinic.com) shows the correct path.
Spin the drum by hand one full rotation to verify the belt tracks straight without riding up or twisting. The belt should sit flat in the wear groove with no visible twist. If it rides to one side, the belt is not seated properly in the idler assembly — release tension and reposition it.
Reassembly and Testing
Reverse the disassembly steps to put the dryer back together. Reattach the front panel, reconnect the door switch harness, lower the top panel, and snap or screw everything into place. Confirm all clips, screws, and connectors are secured before plugging the dryer back in.
Plug in the dryer, push it back into position, and run a test cycle on air-dry (no heat) for five minutes. Listen for smooth, quiet operation. The drum should spin evenly without thumping, squealing, or vibration. If you hear a rhythmic slapping sound, the belt may have a twist — unplug and recheck the routing.
Once confirmed, run a full heated cycle with a load of towels to verify everything works under normal conditions. Knowing how to replace a dryer belt means you can fix this common failure in under an hour, and the repair typically lasts another 8 to 12 years before the next belt wears out.
