LG Dryer bE — Drum drive belt broken or off

LG Dryer · Error code bE

What bE Means

bE (sometimes shown BE) indicates the drum is not rotating. The dryer typically detects this via motor RPM feedback and shuts down, since tumbling without rotation can scorch the load and damage the heater.

Symptoms

  • bE on display shortly after start
  • Motor hums or runs but drum does not turn
  • Loud thumping noise then bE
  • Belt visible at bottom of cabinet

Common Causes

1
Broken drum belt

Belt snapped from age, overload, or jammed item.

2
Belt slipped off idler/motor pulley

Idler spring fatigued and belt jumped a pulley.

3
Seized idler pulley or drum bearing

Rear drum bearing or idler pulley locked up, jamming rotation.

4
Failed drive motor

Motor cannot spin under load.

How to Fix It

  1. Unplug the dryer and pull it forward.
  2. Remove the top and front panels to access the drum belt.
  3. Inspect — if broken or off, route a new belt around the drum, under the idler, and around the motor pulley per the diagram on the cabinet.
  4. Spin the drum by hand and feel/listen for rough drum-bearing rotation; replace the rear drum bearing/felt seal if rough.
  5. Inspect the idler pulley — replace if it does not spin freely or wobbles.
  6. Reassemble and run a No-Heat Fluff cycle to confirm proper drum rotation before adding a load.
