Dryer Squealing or Drum Not Spinning? Idler Pulley 279640 – Fix Belt Tension Fast
A loud squealing, grinding, or thumping noise from your dryer — or a drum that stops turning mid-cycle — is almost always caused by a worn or seized idler pulley. In most Whirlpool, Maytag, Kenmore, and KitchenAid dryers, the idler pulley 279640 maintains constant tension on the drive belt. When the pulley bearing wears out, the belt slips, squeals, or snaps entirely — leaving clothes wet and the drum locked. ⚡ One of the most common failure points in Whirlpool-platform dryers. Part 279640 is the direct-fit OEM and premium XPart replacement that restores proper belt tension, eliminates noise, and gets your dryer running quietly again.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your dryer powers on and the motor runs — you can hear it attempting to turn
- ✔ The drive belt is intact — not snapped or completely off the drum
- ✔ The drum support rollers spin freely — not seized or flat-spotted
- ✔ The motor itself is not seized — it hums or runs when the drum is unloaded
- ✔ ONLY problem is squealing, grinding, belt slippage, or drum that won’t turn under load
Not sure? Send us your model number — we’ll confirm before you order.
🔧 Common Symptoms
- Dryer squealing loudly — most common search: “Whirlpool dryer squeaking noise”
- Grinding or thumping sound during tumble cycle
- Drive belt slipping off the drum or idler arm
- Drum stops turning mid-cycle but motor continues to run
- Dryer drum won’t turn at all — belt intact but no tension
- Visible wear, cracking, or wobble on the idler pulley wheel
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this idler pulley restores normal drum rotation and eliminates noise immediately.

While the idler pulley is out, inspect the drive belt and drum support rollers — these three components wear together and a new pulley on a worn belt will squeal again within months. Replacing all three at the same time is the professional standard and eliminates the most common dryer noise callbacks.
⚙️ Installation
Skill Level: Moderate — 30–60 minutes. Unplug the dryer before beginning. Remove the front panel and lift the drum out to access the idler pulley mounted on the motor bracket at the base of the cabinet. Unhook the drive belt from the old pulley, swap the pulley on the idler arm, and re-route the belt around the drum, idler pulley, and motor pulley in the correct serpentine path. Reassemble the cabinet, plug in, and run a test cycle to confirm quiet operation and proper drum rotation.
💡 Pro Tip
The drive belt routing around the idler pulley and motor shaft is easy to get wrong on reassembly — an incorrectly routed belt will snap within minutes of running. Take a clear photo of the belt path before removing the old pulley. It takes 5 seconds and saves 30 minutes of troubleshooting.
