Samsung Dryer Drum Support Roller & Axle Parts — Models & Compatibility

If your Samsung dryer sounds like it's chewing gravel every time you run a load, the drum support roller is probably shot. This hub covers DC97-16782A — the rear drum support roller and axle assembly that keeps your dryer drum spinning smoothly. Compatible with over 100 Samsung dryer models from 2009 to present, this part replaces several older numbers including DC97-16782C and DC97-07523A.

Is This the Right Part for Your Model?

Check your model number on the inside of the dryer door or on the back panel near the bottom. This roller fits models starting with DV2, DV3, DV4, and DV5 series numbers. If your model matches any in the list below and you're hearing grinding, thumping, or squealing during operation, you've found your problem part.

About This Replacement Part

The DC97-16782A is Samsung's rear drum support roller assembly — the component that bears most of your drum's weight as it spins. Over time, the roller bearings wear out from heat and friction, creating that characteristic grinding noise that gets worse with every load. This assembly includes both the roller wheel and axle, so you're replacing the entire wear point. Samsung used this same basic design across their entire dryer lineup from 2009 through current models, which is why one part number covers so many machines. Most techs replace both the rear roller (this part) and the front idler pulley at the same time since they wear at similar rates.

Common Symptoms

You'll know this roller needs replacement when your dryer develops a rhythmic thumping or grinding noise during operation. The sound typically gets worse as the drum heats up and the worn bearing expands. Some dryers will also vibrate more than usual or the drum might not spin freely when you rotate it by hand with the power off.

Installation Overview

Replacing this roller requires removing the dryer's front panel to access the drum assembly. You'll need to release the drive belt tension, lift the drum forward, and swap out the roller on its rear mounting bracket. The job takes about 45 minutes if you've done it before, closer to 90 minutes for a first-timer. Have a putty knife ready to release the panel clips and a socket set for the mounting bolts.
