LG Dryer Drum Not Spinning — Troubleshooting Guide

A drum that refuses to turn is one of the most obvious dryer failures — clothes sit in a stationary drum and come out wrinkled and still damp. On LG dryers, the most common cause of this symptom is a broken drive belt, followed by worn drum rollers or a failing idler pulley. In less common cases, the motor itself or the inverter board has failed.

Step 1 — Check for an Error Code

Check the display for error codes. E13 (motor overload) and FE (fan/motor fault) are the most relevant codes for a non-spinning drum. AE indicates an inverter board communication fault, which is specific to LG dryers with brushless DC motors. If no code is displayed and the dryer seems to start normally but the drum doesn't move, a broken belt is the most likely cause.

Step 2 — Check the Drive Belt

The drive belt (part 4400EL2001F) is a long, thin rubber belt that wraps around the entire drum, over the idler pulley, and around the motor pulley. When it snaps — which it eventually will with normal use — the motor runs freely but the drum stays still. You can often hear the motor humming without the drum turning. Open the dryer cabinet and look for the belt lying at the bottom of the drum housing or wrapped around the motor. A broken belt is an inexpensive fix ($15–$30) and a DIY-friendly repair.

Step 3 — Inspect Drum Rollers and Idler Pulley

Even if the belt is intact, worn drum support rollers or a seized idler pulley create so much drag that the motor cannot turn the drum efficiently. You will often hear a thumping, squealing, or grinding noise before the drum stops turning entirely. With the dryer unplugged, try spinning the drum by hand — it should rotate with smooth, moderate resistance. Heavy resistance or grinding when you spin it by hand confirms worn rollers or a seized pulley. Replace drum rollers as a set when one fails.

Step 4 — Listen for Motor Behavior

If the dryer is completely silent when you start a cycle (no hum, no click), the motor is not receiving power — check the door switch and the thermal fuse first. If you hear the motor humming but the drum doesn't move, the belt is broken or the motor capacitor has failed. If the motor briefly attempts to start then shuts off, the motor is experiencing thermal overload — this often follows a roller or pulley failure that has been creating excess drag for some time.

When to Call a Technician

If the belt, rollers, and pulley all check out but the drum still won't spin, the motor or inverter board has likely failed. Motor replacements cost $150–$300 in parts — at that price point it's worth getting a technician's diagnosis to confirm before purchasing, since inverter board failures (AE code) can produce identical symptoms at a fraction of the cost.
