Understanding the Problem
When the drive belt on a Samsung DV45H7000GW/A2 wears out or breaks, the dryer drum will not rotate even though the motor runs (or attempts to run). A broken or slipping belt is one of the most common causes of a drum that fails to turn, makes a thumping or squealing noise, or only turns intermittently. Over time belts stretch, crack, or snap due to heat, lint buildup, or age. Replacing the belt is a straightforward repair for a moderately handy person with basic tools. You’ll typically remove the top and front panels to access the drum, inspect the belt and related parts (idler pulley, drum rollers/bearing), and either re-thread a new belt or replace additional worn components. Always disconnect power before starting and verify the model and part number to ensure compatibility.
Common Symptoms
Dryer motor runs but drum won’t turn, loud thumping or squealing, burning rubber smell, drum turns intermittently or slips under load.
Common Causes
- Worn or broken drive belt
- Idler pulley seized or worn (causes belt to slip or rub)
- Worn drum rollers or rear drum bearing increasing friction and wearing the belt

Helpful Repair Tip
Confirm a broken belt by opening the dryer door and turning the drum by hand — if it spins freely without resistance while the motor runs (or you hear the motor but the drum doesn’t turn), the belt is likely broken or slipped off. Also look for visible belt fraying, cracks, or a missing section.
Frequently Asked Questions
How do I know if only the belt needs replacing or if other parts are bad too?
Start by inspecting the belt for breaks, fraying, or glazing. If the belt is intact but the drum is hard to turn by hand or you hear grinding or rumbling noises, check the idler pulley and drum rollers/rear bearing—these increase friction and will wear belts quickly. It’s common to replace the belt plus the idler pulley and rollers as a kit if those components show wear, since they’re easy to access while replacing the belt.
Can I replace the belt myself and how long does it take?
Yes — replacing the belt is a doable DIY job if you have basic tools (screwdrivers, socket set) and follow safety steps (unplug dryer). Typical time is 45–90 minutes depending on your skill and whether you replace rollers/pulley too. Follow a step-by-step guide for your exact model or take photos during disassembly to help with reassembly. If you’re uncomfortable working with appliances, a professional technician is recommended.
