Dryer drum drive belt. This slender belt wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor pulley. If the drum will not turn when the dryer is turned on the belt is likely broken.

When your Samsung dryer drum stops turning but the motor still runs, the drive belt has snapped. It's one of the most common dryer repairs and one of the easiest to fix yourself. The belt wraps around the drum and idler pulley — when it breaks, the drum won't rotate no matter how hard the motor tries.
Most Samsung dryers benefit from replacing the idler pulley at the same time you replace the belt. The pulley keeps tension on the belt, and if it's worn, a new belt will slip or fail prematurely. Repair Clinic carries OEM Samsung dryer belts matched to your exact model number, ensuring the correct width, length, and rib count for proper fit and performance.
Find your Samsung dryer model number on the rating plate inside the door or on the back of the unit. Enter it above to see the correct Samsung dryer belt and idler pulley assembly for your machine.
Samsung dryer belts vary in length, width, and rib count depending on the model series. A belt that's too short won't fit; one that's too long will slip. The safest way to get the exact belt is to enter your full model number (found inside the dryer door or on the back panel) into Repair Clinic's model lookup. We'll show you the exact OEM belt assembly for your machine. If you have the old belt, you can measure it, but model number lookup is always more reliable.
Yes, almost always. The idler pulley maintains tension on the belt. If the pulley is worn — and it usually is by the time the belt breaks — a new belt alone will slip or fail quickly. Replacing both at the same time is the right call and saves you from taking the dryer apart twice. Idler pulleys are inexpensive and come as part of an assembly on Samsung models.
A broken belt is unmistakable: the drum won't turn even though the motor runs and you hear humming. You can also open the dryer cabinet (usually the front panel) and visually inspect the belt around the drum — a snapped or frayed belt is easy to spot. If the drum spins freely by hand with no resistance, the belt is definitely gone or severely damaged.
Universal belts exist, but they're a gamble. Samsung dryer belts have specific dimensions and rib profiles that affect how the belt seats on the drum and pulley. A mismatched belt will slip, wear faster, or not fit at all. An OEM Samsung belt is only slightly more expensive than a universal option and help ensure the correct fit. Enter your model number to find the exact part.

On Samsung dryers, look for the model number on the back panel or inside the door opening, usually on a rating plate or identification label. You may need to open the door fully and check the frame around the opening, or pull the dryer forward to view the rear panel. Copy the complete model number, including letters, numbers, and any characters after a slash, then type it into the model number search to pull up the parts matched to your unit. The model number filters Repair Clinic's full Samsung dryer parts catalog, not just belts, so you can narrow the results to parts designed for your specific machine. You order with confidence knowing the fit is right.
