Understanding the Problem
If your Samsung DV45H7000GW/A2 dryer tumbles slowly, makes thumping or squealing noises, or the drum won't turn at all while the motor runs, the drum (drive) belt is a likely culprit. The belt wraps around the drum and connects to the motor pulley and idler; over time it can stretch, crack or snap, causing the drum to stop turning or to slip under load. Replacing the belt is a common homeowner repair. It requires removing the dryer front or top/rear access panels depending on the model, releasing the tensioner/idle pulley, slipping the old belt off the drum and motor pulley, and routing a new belt around the drum and pulleys before reassembling. While replacing the belt, inspect the idler pulley, drum rollers and motor for wear — if any of those components are damaged or seizing, the new belt can fail prematurely.
Common Symptoms
Drum won't turn or tumbles intermittently, loud thumping or squealing noises during operation, burning rubber smell, or dryer runs but no tumbling.
Common Causes
- Worn, stretched, cracked or snapped drum (drive) belt
- Seized or worn idler pulley or motor pulley causing excessive belt wear
- Worn drum rollers or bearing creating extra drag and prematurely wearing the belt

Helpful Repair Tip
To confirm the belt is the problem, unplug the dryer and try to rotate the drum by hand through the door. If the drum turns freely and you can see a loose or broken belt behind it, the belt is the faulty part. If you hear grinding or the drum is stiff, also inspect the rollers and idler pulley.
Frequently Asked Questions
How long does it take to replace the dryer belt on a DV45H7000GW/A2?
For a competent DIYer with basic tools, belt replacement typically takes 45–90 minutes. Time depends on whether you also replace rollers or the idler pulley. Always unplug power before beginning and follow the model-specific service instructions or manual.
How much will a replacement belt cost and do I need other parts?
The belt itself (OEM or quality aftermarket) typically costs between $15–$50. If the idler pulley or drum rollers are worn, replacing those at the same time is recommended; combined parts may range $30–$120 depending on OEM vs aftermarket. Labor cost at a repair shop varies, but expect an additional service fee if you don't do it yourself.
