Understanding the Problem
The drive belt on an LG DLG2102W dryer wraps around the drum and motor pulley. When it wears, frays, or snaps the drum won't turn or will slip, causing loud thumping, burning rubber smell, or no tumbling at all. Below are practical diagnostic and repair steps you can follow. 1) Confirm the symptom - Try to turn the drum by hand (with the dryer off and unplugged). A healthy belt will provide firm resistance; a snapped belt will let the drum spin freely or flop. - Listen during a cycle: a loud thump, squeal, or rubbing noise often indicates a damaged belt or seized idler. - Look inside the cabinet and behind the back panel for visible belt damage (fraying, missing sections, or rubber shards in the lint trap area). 2) Tools and preparation - Tools: screwdriver set (Philips and flat), nut driver or socket set (1/4", 5/16" or 5/16/7/16 common), putty knife (to release top clips if needed), work gloves, flashlight. - Parts: replacement drive belt (order by model/serial — see parts list below), optionally idler pulley and drum rollers if worn. - Safety: unplug dryer. For gas models, shut off gas supply and ensure ignition components are cool before working. 3) Basic diagnosis (quick checks) - Unplug the dryer. Remove the lint screen and feel for small rubber bits — evidence of a shredded belt. - Access the drum: depending on model you may remove the top and front panel, or the rear panel. For DLG-style LG dryers the front panel/top may need removal to access the belt and idler. - Inspect belt path: check the belt for cracks, glazing, missing teeth (if ribbed), or complete break. Check idler pulley for free spin and no wobble. Inspect drum roller bearings for roughness. 4) Replacing the belt (typical step-by-step) - Step 1: Unplug the dryer and shut off gas if applicable. - Step 2: Remove the lint screen, then remove the screws along the top near the lint area if required and lift off the dryer top (or use the putty knife to release clips). - Step 3: Remove the front panel: disconnect door switch connector if present, remove retaining screws, and lift the front away to expose the drum. - Step 4: Slide the drum forward slightly to access the belt and idler. If belt is intact but loose, note its routing: around the drum, then under and around the idler, and around the motor pulley. - Step 5: Release tension on the idler pulley and remove the old belt (if snapped, pull off drum). Inspect idler pulley and rollers; replace if they are noisy, seized, or have excessive play. - Step 6: Route the new belt: feed the belt under the idler and around the motor pulley, then loop it around the drum following the original rib pattern inward toward the drum surface. Most LG dryers have the ribbed side of the belt contacting the motor pulley and idler — match the old routing. - Step 7: Seat the belt in the drum grooves and rotate the drum by hand to confirm proper tracking and tension. The idler should keep the belt snug against the motor pulley. - Step 8: Reassemble the front panel and top, reconnect the door switch, replace screws and the lint screen. - Step 9: Plug dryer back in, restore gas if applicable, run a short test cycle to confirm drum spins smoothly without noise. 5) Additional checks if drum still won’t turn - Check motor: if belt is intact and tensioned but motor does not turn or hums, test motor and centrifugal switch. Also check thermal fuse and door switch for open circuits (use a multimeter if comfortable). - Inspect drum support rollers and glides: a seized roller can lock the drum even with a good belt. Safety note: Always unplug the dryer (and shut gas off for gas models) before working on the machine. If you’re unsure about gas connections, thermostat, or electrical testing, hire a qualified technician.

Frequently Asked Questions
How much does it cost to replace the dryer belt on a DLG2102W?
Parts for a replacement drive belt typically cost between $15–$40 depending on whether you buy OEM or aftermarket. If you replace idler pulley or rollers as preventative maintenance, add $10–$50 each. Labor for a service call varies by region but expect $80–$150 if you hire a technician.
Can I run the dryer with a damaged belt until I have time to replace it?
No. Running the dryer with a damaged or partially shredded belt risks further damage to the drum, motor, and other components, and can create a burning-smell/fire hazard. Turn the dryer off and replace the belt before using it again.
