Understanding the Problem
If your Samsung DV45H7000GW/A2 dryer drum won’t turn, spins intermittently, makes a thumping or squealing noise, or emits a burning rubber smell, the drum belt is a likely culprit. The belt wraps around the drum and connects it to the motor; over time the belt can stretch, crack, fray, or break. When that happens the motor may run but the drum won’t turn, or the belt may slip and cause noise and reduced drying performance. Replacing the belt is a common, straightforward repair for this model and can usually be completed with basic hand tools in 30–60 minutes. Before replacing the belt, inspect the drum support rollers, idler pulley, and motor pulley — worn rollers or a seized idler can wear a new belt prematurely. Always disconnect power before starting the job and follow safe disassembly steps to avoid damage to the cabinet or wiring.
Common Symptoms
Drum not turning while motor runs, loud thumping or squeal during operation, burning rubber odor, intermittent tumbling, or drum slipping under load.
Common Causes
- Belt wear and fatigue leading to cracking, fraying, or breakage
- Idler pulley or motor pulley worn or seized causing belt slip or rapid wear
- Drum rollers or bearings worn, causing extra drag and premature belt failure

Helpful Repair Tip
Unplug the dryer and manually rotate the drum. If you feel a loose or dangling belt, see visible fraying, or the drum spins freely with no resistance, the belt is broken or slipped. Also check the idler pulley and drum rollers for roughness — they often fail with belt problems.
Frequently Asked Questions
How do I know which belt fits my DV45H7000GW/A2 dryer?
Check the appliance model tag (usually inside the door opening or on the back) and use that full model number when searching parts. Many suppliers list compatibility; if an exact OEM number isn’t shown, measure the old belt (circumference/length and rib count) — a common replacement spec for many Samsung front-load dryers is a 1540 H7 6-rib belt, but you should confirm fit for DV45H7000GW/A2 before buying.
Can I replace the belt myself and how hard is it?
Yes — replacing the drum belt on the DV45H7000GW/A2 is a moderate DIY job that typically requires a screwdriver, nut driver, and sometimes a socket set. Time is usually 30–60 minutes. Important steps: unplug the dryer, remove the top and front or rear access panels per your model’s service sequence, release the idler to remove the old belt, route the new belt around the drum and pulleys correctly, then reassemble. If you’re uncomfortable with disassembly or working near the motor and electrical components, consider hiring a qualified technician.
