LG Dryer Repair in Toronto — Drum not spinning

• Broken or stretched drive belt is the number-one LG not-spinning call: the motor runs and the blower spins, but the drum sits dead or free-wheels with a thump. LG uses the 4400EL2001A poly-V drum belt across the DLE/DLG/DLEX line. The diagnostic is to open the top and spin the drum by hand — if it turns free with zero resistance, the belt has snapped or jumped the idler. We thread the new belt over the drum and back onto the idler and motor pulley, and because a belt that stretched almost always rode wrong over a tired idler, we inspect the idler in the same pass.
• Seized or worn idler pulley is the second classic and usually the reason the belt let go: the spring-loaded idler keeps tension on the 4400EL2001A belt, and when its bearing dries out and seizes (typically after the chirp/squeal that tracks drum speed), the belt slips off the motor pulley and the drum stops. We carry both the pulley-only 4560EL3001A and the complete 4561EL3002A idler assembly (arm + tension spring), and on a not-spinning call with idler wear we replace belt + idler together so the machine doesn't come straight back.
• Drive motor failure — LG 4681EL1008A (supersedes 4681EL1002A/B, 4681EL1006A/F, 4681EL1008B/H/K; current LG supersession EAU30126201). Signature is a motor that hums or buzzes on start but won't turn the drum, or one that runs a few minutes then trips its internal thermal overload and only resets after it cools. Before condemning the motor we always rule out a bound roller, a seized idler, and a jammed blower wheel first, because a dragging drive train fakes a dead motor on this platform far more often than the windings actually fail. A hum with the belt off and the drum turning free by hand is what actually points at the motor.
• Worn drum support rollers binding the drum: LG drums ride on support rollers (original bushing-style 4581EL2002A, now superseded by the upgraded ball-bearing 4581EL2002L low-noise kit). When the roller bushings dry out and stop spinning freely, the drum drags, the motor overloads, and it presents as 'ran a minute, then quit turning' or a loud rumble that ends in no-spin. We replace rollers as a set, not one at a time, because a flat-spotted roller means its mate is worn too and a binding roller also chews the belt. The hand-spin test with the belt pulled separates this from a motor or control fault — stiff or noisy rotation means rollers.
• Rear felt drum seal worn through (4036EL3001A) letting the drum shift and scrape until it binds: once a roller bearing has run too long it scores the shaft and chews the rear felt seal, the drum drops out of true, scrapes the back panel, and the added drag can stall the motor. We check and renew the 4036EL3001A seal whenever the back panel is already off for a roller or belt job, so the not-spinning complaint doesn't come back as a scrape-then-stall.
• No-spin that is really a no-start in the motor circuit: on LG the drum only energizes when the door circuit closes, so a failed door switch (6601EL3001A) leaves the drum dead with the console still lit and the cycle counting down — this can throw the dE door error. We listen for the door 'click' and meter the switch for continuity before pulling panels, so we're not chasing a sub-$40 switch the long way. We also confirm the displayed code: dE is the door circuit and CL is child-lock (a held-key setting, not a fault), both of which un-book a 'won't run' call without parts.
• Heat-pump compact condo models (DLHC Dual Inverter HeatPump units like the DLHC1455W) are a separate not-spinning story: the drum drive and the compressor/circulation loop are different systems, so a DLHC that won't tumble is triaged by model/serial before quoting — belt, idler and rollers on these compacts are not the vented DLE stock, and we confirm availability before promising a same-visit fix rather than assuming the 4400EL2001A / 4581EL2002L vented parts fit.

LG drum not spinning in Toronto — the local specifics

• The recurring LG-in-Toronto not-spinning pattern is the belt-and-idler pair: the idler bearing dries out and squeals for a while in our dry-heated winter laundry rooms, then it seizes and the belt slips or snaps and the drum free-wheels — so we treat a not-spinning LG as a belt + idler job by default and inspect the rollers in the same opening, because replacing the belt alone over a tired idler is what brings these machines back. On higher-mileage units the binding-roller-then-motor-overload presentation is the other recurring story we see.
• We roll to LG not-spinning calls carrying the 4400EL2001A drive belt, the 4561EL3002A idler assembly (arm + spring) and 4560EL3001A pulley, the 4581EL2002L ball-bearing drum roller kit, and the 4036EL3001A rear felt seal so a belt/idler/roller fix is one visit; we keep the 6601EL3001A door switch on the van for the 'console lit, drum dead' / dE no-start, and confirm a 4681EL1008A drive motor by model/serial before dispatch when the hand-spin test points past the drive train.
