Quick answer: A dryer drum that won't spin is most often caused by a broken drive belt — the drum turns freely by hand with almost no resistance when the belt is snapped. The second most common cause is a worn drum roller or bearing. Both are repairable; drive belt replacement is a realistic DIY job on most Samsung, LG, Whirlpool, and GE dryers.
When a dryer runs — heating, making noise — but the drum sits completely still, laundry backs up fast. The good news is that drum-not-spinning faults almost always come from mechanical components that have a clear lifespan, and most can be diagnosed without any specialized equipment. This guide covers the seven most common causes on Samsung, LG, Whirlpool, and GE dryers, along with repair costs in the Toronto and GTA area for 2026.
The drive belt is a long, thin rubber loop that wraps around the drum, the motor shaft, and the idler pulley. When it snaps — which it will eventually after years of heat and tension — the motor runs freely but the drum sits still. This is by far the most common reason a dryer drum stops turning.
The quick test: Open the dryer door and try rotating the drum by hand. If it spins easily with almost no resistance — almost like it is floating — the drive belt is broken. A drum with an intact belt and functioning rollers should offer moderate resistance.
Which brands are most affected: Drive belt failures are common across all major brands. On Samsung front-loaders, the belt path is slightly more complex than on older top-loaders. LG DLE and DLGX series dryers, Whirlpool WED series, and GE GTD models all use similar rubber multi-rib belts with expected lifespans of 8–12 years.
Fix: Remove the front panel (or rear panel on some GE models), lift the drum slightly, slip the broken belt off, and route the new belt around the drum, under the idler pulley, and onto the motor pulley. OEM belts cost $15–$30. Budget 1–2 hours for a first-timer. When replacing the belt, inspect the idler pulley and drum rollers at the same time — if one component is worn, the others often are too.
Most dryers support the rear of the drum on two or four rollers (sometimes called drum support rollers or drum glide rollers). When these rollers wear out — their rubber surface flattens or the axle bearing fails — the drum can seize or drag severely enough that the motor cannot turn it, even with the belt intact.
Symptoms before failure: Worn drum rollers almost always announce themselves first. A rhythmic thumping, squealing, or grinding noise during operation that matches the speed of drum rotation is the classic warning sign. If you ignored that noise for a few months, a completely seized drum is the likely result.
How to confirm: With the belt removed, spin each roller by hand. Rollers should spin freely and smoothly. Any roller that wobbles, has flat spots, or does not spin freely needs replacement. On most dryers, rollers come in kits of 2 or 4 — always replace the full set, not just the obviously worn one.
Fix: Drum roller replacement requires removing the front panel and drum, pressing the old rollers off their axle shafts, and pressing new ones on. The repair is physically demanding and fiddly for first-timers. A roller kit typically costs $25–$50 for OEM parts. Labour is the main expense here.
The drive motor powers both the drum (via the belt) and the blower fan. When a motor fails, the dryer may produce a humming sound as the motor tries to start but cannot, or it may be completely silent. Some motors have a thermal overload protector that cuts out when the motor overheats — in that case, the dryer may work fine after a 30-minute rest period before failing again.
How to distinguish motor failure from a belt issue: With the belt intact, if you can hear the motor humming but the drum will not turn even when you try to push it manually during operation, the motor may be seized. If the dryer is completely silent when you press Start — no hum, no movement — the motor may have failed entirely or the start capacitor has died.
Fix: Motor replacement is a significant repair. The motor is typically mounted to the base of the cabinet, with the blower fan attached to one shaft and the belt to the other. Replacing it requires full cabinet disassembly. Given the part cost ($80–$150 for OEM) plus labour, weigh the repair cost against the age of the appliance before committing.

(437) 747-6737 Book OnlineDryers will not start — and therefore will not spin — if the door switch does not confirm the door is fully closed. A door latch or door switch that has cracked, worn out, or lost proper spring tension can prevent the control board from energizing the motor, even when the door appears fully closed.
How to confirm: Open and firmly close the dryer door. Listen for a solid click from the latch. If you press Start and nothing happens — no sound, no drum movement, no heat — but the display or indicator lights work, the door switch is a prime suspect. You can test the switch with a multimeter set to continuity: with the door closed (switch actuated), it should read continuity. With the door open, it should read OL.
Fix: Door switches on most dryers are accessible by removing two or three screws from the door frame interior. The part itself costs $10–$25. This is one of the simpler DIY dryer repairs available.
The idler pulley keeps tension on the drive belt. It is a spring-loaded arm with a wheel at the end. When the pulley wheel's bearing fails, the pulley seizes — which either snaps the belt immediately or creates so much friction that the motor cannot turn the belt under load. A squealing or grinding noise that gets worse over time is the typical precursor.
How to confirm: With the dryer unplugged and the front panel removed, spin the idler pulley wheel by hand. It should rotate smoothly and freely. Any grinding, wobbling, or seizing means it needs replacement. On most models, the idler pulley is held in place by a single screw or clip and can be swapped out in minutes once you have access.
Fix: The idler pulley part itself costs $15–$35. When replacing the pulley, always replace the drive belt at the same time — a worn pulley accelerates belt wear. If both components are near end of life, replacing them together saves a second labour call later.
The front of the drum rests on plastic or felt glides (also called drum slides or drum pads) that allow it to rotate smoothly against the front bulkhead. When these glides wear through — which happens gradually over thousands of cycles — the bare metal drum drags against the plastic or metal bulkhead, creating friction that can slow or stop drum rotation.
Worn glides produce a scraping, squeaking, or thumping noise before the drum stops. On Samsung and LG front-load-style dryers, glide wear is more common than on traditional top-loading designs due to the larger drum circumference and higher contact pressure.
Fix: Replacing drum glides requires removing the front panel, drum, and the old glide clips or felt strips from the front bulkhead. A glide kit costs $20–$40. The labour involved in full drum removal makes this a moderately complex repair best done alongside any belt or roller work to maximize value from the disassembly.
The main control board sends the start signal to the motor relay. If that relay fails in the open position, the motor never receives power and the drum never moves — even if every mechanical component is in perfect working order. Control board failure is the least common cause of a non-spinning drum but should be considered after all other components have been tested.
On newer Samsung and LG dryers with digital displays, a control board fault often — but not always — produces an error code. If the display lights up normally, accepts button input, but nothing happens when you press Start, and the door switch tests good, the motor circuit on the control board may have failed.
Fix: Control board replacement requires accurate diagnosis to confirm the board — not the motor start capacitor or wiring harness — is at fault. Boards cost $100–$200 for OEM parts. This diagnosis and repair is best handled by a technician.

The door switch and drive belt are the two most approachable DIY repairs on this list. Drum rollers, idler pulley, and drum glides are manageable for experienced DIYers since they require full disassembly but no specialized tools beyond a screwdriver set and multimeter. Motor and control board replacement should go to a technician.

When to replace instead of repair:
The most common cause of a dryer that runs — you can hear the motor hum — but the drum does not turn is a broken drive belt. The belt wraps around the drum and the motor pulley; when it snaps, the motor spins freely but the drum stays still. A worn idler pulley or drum rollers can also prevent spinning even with an intact belt.
Open the dryer door and try to turn the drum by hand. If it spins with very little resistance — almost no tension — the drive belt is almost certainly broken. A functioning dryer drum with an intact belt should offer moderate resistance when turned manually. You can confirm by removing the front or rear panel and visually inspecting the belt path around the drum.
Yes, drive belt replacement is one of the more accessible DIY appliance repairs. On most Samsung, LG, Whirlpool, and GE dryers, you need to remove the front panel, lift the drum slightly, slip the old belt off, route the new belt around the drum and idler pulley, and reassemble. The part costs $15–$30. Budget 1–2 hours if you have not done it before.
Worn drum rollers typically produce a loud thumping, squealing, or grinding noise during operation before they fail completely. The sound tends to be rhythmic and coincides with drum rotation. If you noticed these sounds before the drum stopped turning, drum rollers or the axle bearings are the most likely culprits.
Drive belt replacement runs $130–$200 all in (parts and labour) in the Toronto area. Drum roller replacement is $150–$230. Motor replacement is the most expensive at $250–$400. Nick's Appliance Repair charges a $65 diagnostic fee that is credited toward the repair, so you pay nothing extra for diagnosis when we do the work.
A humming motor with a stationary drum almost always means a broken drive belt. The motor is running but has nothing to turn. Less commonly, a seized drum bearing or a jammed foreign object — a coin or button — can lock the drum while the motor runs. Check the drum interior for obstructions before disassembling anything.
