Quick Summary
- Main symptom: Dryer runs and heats but drum does not spin
- Difficulty: Intermediate — requires disassembling the front panel
- Time: 60–90 minutes
- Belt cost: $15–$40 depending on brand and model
- Call a tech if: You are uncomfortable disconnecting wiring or routing the belt around the idler pulley
If your dryer turns on, you can hear the motor running, and heat is coming out — but the drum is completely still — a broken drive belt is almost certainly the culprit. The dryer belt is a long, thin rubber belt that wraps around the drum and connects to the motor via a spring-loaded idler pulley. Over time, the belt stretches, frays, and eventually snaps.
Replacing a dryer belt is a manageable intermediate repair. It requires disassembling the front panel of the machine, but no special tools beyond a screwdriver and a nut driver. This guide covers the signs of a broken belt, the tools and parts you need, step-by-step replacement, and when to hand the job to a certified technician.
Signs Your Dryer Belt Is Broken
The following symptoms point specifically to a failed drive belt:
- Drum not spinning at all — the motor hums and the dryer heats up, but the drum is completely stationary when you open the door. This is the signature broken-belt symptom.
- Thumping or slapping noise — a worn or stretched belt will slap against the inside of the cabinet before it fully breaks. This warning sign can appear days or weeks before the belt snaps.
- Clothes still damp after a full cycle — if the drum spins only intermittently due to a partially slipping belt, clothes will not tumble properly and will come out wet.
- Burning rubber smell — a belt that is slipping against the drum or motor pulley can produce a faint rubber smell. Do not ignore this — it means the belt is on its way out.
Quick test: Open the dryer door and try spinning the drum by hand. A drum with a broken belt will spin very freely with almost no resistance. A drum with an intact belt will have moderate resistance from the motor and idler pulley tension.
What You Need
Brand-Specific Notes Before You Start
While the general process is similar across brands, each has minor quirks:
- Whirlpool / Maytag / KitchenAid: The top panel lifts on spring clips released with a putty knife. The front panel is secured by two screws inside the top opening. Very common repair — parts are widely available.
- Samsung: Some models require removing the rear panel instead of the front. Check your model before starting. The idler pulley spring tension can be high — use caution when routing the belt.
- LG: Front-access design similar to Whirlpool. The belt routing passes under the drum and around the motor pulley in a figure-eight pattern on some models.
- GE / Hotpoint: Often accessed from the front. The drum may need to be tilted forward rather than slid out.
- Bosch / European models: Usually accessed from the rear or top. These are more complex and are generally better handled by a technician.
Step-by-Step: Dryer Belt Replacement
Unplug the dryer and shut off gas (gas models)
Pull the power plug from the wall. For gas dryers, close the shut-off valve on the supply line. Never work on a live appliance. Pull the dryer out from the wall so you have room to work around it.
Remove the lint screen and open the top panel
Pull the lint screen out. On most Whirlpool-platform dryers, slide a putty knife into the seam between the top panel and the front of the cabinet about 2 inches from each corner. Press inward to release the spring clips, then hinge the top panel up and lean it against the wall behind the dryer.
Remove the front panel screws and disconnect the door switch
With the top open, look inside the top corners of the front panel for two Phillips or hex screws. Remove them. Carefully lift the front panel away from the cabinet. Before setting it aside, photograph the door switch wiring harness, then unplug it. Set the front panel safely to the side.
Locate and remove the broken belt
Look at the bottom of the drum cabinet — you will see the idler pulley (a spring-mounted wheel) and the motor pulley. The old belt (or the remains of it) will be wrapped around the drum and looped under the pulleys. Unroute the belt from the pulleys and slide it off the drum. Note the routing path — you will mirror it with the new belt.
Route the new belt around the drum
Drape the new belt around the middle of the drum with the ribbed side facing the drum surface. Reach down and loop the belt under the idler pulley first (pressing the pulley arm toward the center to release tension), then loop it around the motor pulley. The belt should be taut when you release the idler pulley spring. Give the drum a manual spin to confirm the belt stays in place and tracks properly.
Reassemble the dryer
Reconnect the door switch wiring harness (plug clicks in). Lift the front panel into position — the bottom edge hooks into the bottom frame first, then press the top into the cabinet opening and reinstall the two screws. Fold the top panel back down until both spring clips snap in. Reinsert the lint screen.
Test the dryer
Plug the dryer back in (and open the gas valve on gas models). Start a timed dry cycle. The drum should spin smoothly, evenly, and quietly. Run it for at least 5 minutes to confirm no slipping, thumping, or squealing — which would indicate the belt is not routed correctly or the idler pulley also needs replacement.
While you have it open: Inspect the drum support rollers (the small wheels the drum rests on) and the idler pulley for wear. If the rollers are flat-spotted or the idler pulley is stiff or noisy, replace them at the same time. Parts are inexpensive and it saves a second disassembly later.
When to Call a Certified Technician
Dryer belt replacement is a reasonable DIY project for mechanically inclined homeowners. However, we recommend calling a technician if:
- You are not comfortable disconnecting and reconnecting wiring harnesses
- Your dryer is a rear-access model (common on some Samsung and European brands) and you cannot locate clear disassembly instructions for your exact model
- The belt replaced correctly but the drum still does not spin — this points to a failed motor or capacitor, which requires a technician
- You find damaged wiring, a cracked drum, or significant rust inside the cabinet during the repair
- The dryer is under warranty — DIY repairs can void manufacturer coverage
Our certified technicians cover all major brands across the GTA. A dryer belt replacement, including labour and parts, typically costs $150–$250. We carry common parts on the truck, so most repairs are completed in a single visit. $89 diagnostic fee — waived with repair.

In most cases we can book your appliance repair the same day or the next day in the Greater Toronto Area, and the majority of repairs are completed in that single visit.
The clearest sign is the dryer running normally — motor humming, heat working — but the drum not spinning at all. You may also hear a thumping or slapping noise before the belt fully breaks, caused by a fraying or loose belt slapping inside the cabinet.
Most dryer belts last 8 to 12 years under normal use. High-volume households doing 10+ loads per week may see belts wear out sooner. The belt is one of the most common dryer wear parts along with drum support rollers and idler pulleys.
No. If the belt is broken the drum will not spin and your clothes will not dry. Running the dryer without a spinning drum can also overheat the heating element, potentially causing other damage. Stop using it until the belt is replaced.
The belt itself costs $15 to $40 depending on brand. Professional installation typically runs $150 to $250 including parts and labour. A technician will often inspect the idler pulley and drum rollers at the same time, since replacing worn rollers when the belt is already off saves a second service call.
It is rated intermediate difficulty. You need to disassemble the front panel of the dryer, which requires comfort working with appliance components. If you are unsure about disconnecting wiring harnesses or routing the belt around the idler and motor pulleys, a certified technician is the safer choice.
Yes — belts are model-specific. Using the wrong belt will either not fit or will slip off. Always look up your model number (found on the door frame sticker) and order the OEM or compatible belt for that exact model.
Strongly recommended. The idler pulley endures as much wear as the belt itself. If the pulley is noisy, stiff, or wobbling, replace it while the dryer is already open. The additional part cost is small and it prevents a second service call within months.
