Samsung Dryer Repair in Toronto — Drum not spinning

• Snapped or stretched drive belt (#6602-001655): the motor runs and the blower pushes air but the drum free-wheels by hand — RepairClinic lists this exact part as the fix for a Samsung dryer that won't spin (symptoms: Noisy, Drum Not Spinning, Won't Start). On this platform the belt almost never fails alone; we inspect the idler in the same visit because a seized pulley is what burned it.
• Seized idler/tension pulley (DC93-00634A): when the pulley wheel locks up it drags the belt across a stationary surface until the belt overheats, glazes and snaps. Samsung and the parts channel sell the idler and belt 6602-001655 together as a kit for precisely this reason — replacing only the belt on a bad idler just buys a second breakdown.
• Worn drum support rollers (DC97-16782A): the original sleeve-bearing rollers develop flat spots and bind, so the drum becomes hard to turn by hand and the motor stalls or the belt slips rather than spin a dragging drum. We fit the upgraded sealed ball-bearing DC97-16782E rollers — RepairClinic and the parts channels flag the noisy / won't-turn symptom set as the trigger for this part.
• Failed drive motor (DC31-00055G; genuine OEM supersessions DC31-00055H / DC31-00055D, PS4204647): the classic 'hums but won't spin' Samsung. With a confirmed-good belt and free-turning drum, a humming motor that won't start the drum has a failed start winding or seized motor bearing — we confirm voltage to the motor before condemning it, since a binding roller mimics the same hum.
• Door switch not closing the circuit (DC64-00828A): a Samsung that lights up and beeps but won't start the drum is very often the door switch, not the motor. We test the switch for continuity on the latch before pulling the cabinet — RepairClinic lists won't-start / no-tumble as the door-switch symptom, and it's the cheapest of the not-spinning causes to rule out.
• Belt-broken vs. belt-thrown diagnosis: because Samsung routes the belt over both the motor pulley and the idler, a belt that 'jumped the track' presents identically to a snapped belt (drum free, motor runs). We verify belt routing and idler-arm spring tension on reassembly so the new 6602-001655 doesn't walk off again.
• Start/control logic vs. mechanical: before any teardown we confirm the cycle actually starts (Time Dry, hold Start, timer counts down) and rule out Child Lock — Samsung's own troubleshooting calls these out — so we never sell a belt or motor on a dryer that was only locked out at the panel.

Samsung drum not spinning in Toronto — the local specifics

• The recurring Samsung pattern in Toronto is the belt-and-idler pair, not the belt alone: drums that free-wheel by hand almost always trace back to a seized DC93-00634A idler that cooked the 6602-001655 belt, so we plan the visit to replace both and inspect the rollers. The second most common not-spinning call is the 'hums but won't turn' DV42/DV45 — usually worn DC97-16782A rollers binding the drum before it's ever the DC31-00055G motor.
• To every Samsung not-spinning call we bring the paired belt 6602-001655 + idler DC93-00634A, the upgraded ball-bearing roller set DC97-16782E, and we keep door switch DC64-00828A and drive motor DC31-00055G on the van so a humming-motor or won't-start-no-tumble diagnosis still closes in one trip.
