Understanding the Problem
If your Samsung DV45H7000GW/A2 dryer stops tumbling, makes squealing or thumping noises, or runs but the drum doesn’t turn, the drive belt is one of the most likely culprits. The drive belt wraps around the drum and connects it to the motor and idler pulley; over time the belt can stretch, crack, fray, or break, or it can slip off the pulley assembly. A failed belt prevents the drum from turning even though the motor may be running. Replacing the belt is a common DIY repair for this model. Before replacing the belt, inspect the idler pulley and drum rollers because a seized or worn pulley or roller can rapidly wear a new belt. Also check for obstructions inside the dryer and verify the motor is running (you may hear it) to confirm the belt is the actual cause.
Common Symptoms
Dryer runs but drum does not tumble; loud squealing or rubbing noises; visible frayed, glazed, or snapped belt; intermittent tumbling; burning rubber smell.
Common Causes
- Drive belt worn, cracked, or snapped from normal wear
- Belt slipped off the idler pulley or motor shaft due to looseness or misalignment
- Worn/drum rollers or seized idler pulley creating excess drag and causing belt failure

Helpful Repair Tip
Open the front access (or remove the top/back depending on your model) and manually spin the drum. If it turns freely and the motor runs but the drum won’t turn during a cycle, the belt is likely broken or has slipped. Compare the old belt’s length/profile or the OEM part number stamped on it to ensure you order the correct replacement.
Frequently Asked Questions
Can I replace the dryer belt myself, and what tools do I need?
Yes — replacing the belt on a Samsung DV45H7000GW/A2 is a common DIY job for someone comfortable with basic appliance repair. Typical tools: Phillips and/or Torx screwdrivers, socket set or nut driver (usually 7/16" or 11/32"), work gloves, and optionally a putty knife to release clips. Always unplug the dryer and turn off the gas (if gas model) before starting. Follow step-by-step instructions: remove the top/front panel to access the drum, loosen the idler and motor tension to remove the old belt, route the new belt around the drum and pulleys, reassemble and test.
How much does a replacement belt cost and how long will the repair take?
A replacement belt typically costs between $10 and $40 depending on OEM vs aftermarket and where you buy it. If you already have the tools and basic skills, the repair usually takes 30–60 minutes. If you discover worn rollers or a bad idler pulley those parts add cost and time (another 30–60 minutes to replace). Always verify the exact part number for your model before ordering.
