Dryer Squealing or Drum Not Turning? Samsung Belt & Roller Kit DC97-16782A – Fix Drum Drive Failure Fast
If your Samsung or Kenmore (Samsung-built) dryer is squealing, thumping, or the drum has stopped turning entirely, a worn drive belt, failed drum support rollers, or a seized idler pulley is the most common cause. In most Samsung dryers, these three components wear together — when one fails, the others are close behind. When the belt breaks or rollers seize, the drum stops rotating, the motor runs unloaded, and continued operation risks burning out the motor. ⚡ Replacing the full kit now prevents a secondary motor failure that costs 3–5× more. Kit DC97-16782A is the complete OEM maintenance set — drum support rollers (DC97-16782A), idler arm and pulley assembly (DC93-00634A), and drive belt (6602-001655) — that restores full drum rotation and eliminates noise immediately.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Dryer powers on and motor runs normally
- ✔ Drum is not turning, or turns with loud squealing, thumping, or grinding
- ✔ Power supply and door switch confirmed OK
- ✔ ONLY problem is drum drive failure — not a heating or electrical fault

🔧 Common Symptoms
- Loud squealing or squeaking throughout the entire cycle
- Rhythmic thumping or banging as drum rotates
- Drum completely stationary — motor runs but drum does not spin
- Drive belt visibly broken or lying loose inside the drum cabinet
- Dryer stops mid-cycle due to drum resistance tripping thermal cutoff
- Uneven drum rotation or wobble felt through the door
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing the full belt and roller kit restores normal operation immediately.

While the drum is out, inspect the drum felt seal (DC97-07509B). A worn or cracked felt seal allows lint to bypass the drum and accumulate around the motor and heating element — a fire and reliability risk. Replacing the seal during the same service call adds minimal time and eliminates a common callback. Also check the moisture sensor bars inside the drum for buildup.
⚙️ Installation
Skill Level: MODERATE — 60–90 minutes. Disconnect power before servicing. Remove the top panel and front panel to access the drum. Lift the drum to release belt tension and slide the old belt off the motor pulley. Replace all rollers and the idler pulley at the same time — never replace only the belt on a noisy dryer. Reinstall the belt in the correct Z-wrap pattern around the drum, idler, and motor shaft. The idler spring provides correct tension automatically — do not overtighten.

💡 Pro Tip
The standard OEM rollers use a sleeve bearing that wears out again within 2–4 years under heavy use. Our XPart (Ball Bearings) variant includes upgraded ball-bearing drum support rollers that last significantly longer and run quieter. If you're already doing the repair, the incremental cost of the upgrade is minimal compared to a second disassembly. Choose the XPart (Ball Bearings) option above for the longest-lasting repair.
