Samsung Dryer Drum Drive Belt Parts — Models & Compatibility

If your Samsung dryer won't spin, makes high-pitched squealing noises, or the drum sits completely still while the motor runs, the drive belt is usually the culprit. This hub covers the 6602-001655 belt replacement that fits over 50 Samsung and Kenmore dryer models, including the popular DV42H, DV45H, and DV48J series.

Is This the Right Part for Your Model?

Check your model number on the sticker inside the dryer door frame or on the back panel near the power cord. The 6602-001655 belt replaces Samsung part numbers AP4373659, 6602-001314, PS4133825, and 1935594. If your model matches the compatibility list below, this belt will work. Models like the DV42H5000EW/A3, DV48H7400EW/A2, and DV50K8600EV/A3 all use this exact belt.

About This Replacement Part

The drum drive belt wraps around your dryer drum, idler pulley, and motor shaft to spin the drum when the motor runs. Over time, this belt stretches from heat cycles and friction — eventually it snaps or slips off completely. When the idler pulley bearings wear out simultaneously, you'll hear grinding or squealing before the belt fails. One owner described it perfectly: "My Samsung dryer was making a grinding noise when running," which typically means both the belt and idler assembly need attention. The belt itself is a straightforward 30-60 minute repair if you're comfortable disassembling the front panel, though you'll need to remove about half the dryer's exterior panels to access everything. Expect sharp sheet metal edges and plastic clips that break easily on the control panel, so work carefully and keep a towel handy for protection.

Common Failure Scenarios

The belt can stretch over time or break completely, and the idler pulley bearings can wear out causing squealing or grinding noises before total failure. You'll know it's time when the drum won't turn at all, or when you hear metal-on-metal screeching during cycles. Some users report flashing error lights when the belt snaps — the dryer's sensors detect the drum isn't moving and trigger a fault code.

Installation Tips from Real Repairs

• Use a shop vacuum to clean out all the lint while you've got the dryer opened up — especially the duct piece between the lint trap and blower housing
• Check the drum support wheels to make sure they spin freely; seized wheels will kill your new belt prematurely
• Put a dab of high-temperature grease on the idler tensioner plate where metal contacts metal — this reduces wear and squeaking
• Wear work gloves throughout the entire job; the sheet metal edges are razor-sharp
• Consider replacing the complete idler assembly along with the belt, especially if you heard grinding noises before failure

Tools You'll Need

Screwdrivers (Phillips and flathead), adjustable wrench, socket set, pliers, and work gloves. The entire repair takes 30-60 minutes for most DIYers, and the difficulty level is rated easy if you follow a video guide.
