Does it thump once per drum turn?
Suspect drum rollers, roller shafts, or a flat spot. The sound usually repeats at a steady drum rhythm.

LG Front Load Gas Dryer Making Noise? Match the Sound
Stop for gas odor, burning smell, scraping metal, or a dropped drum. If the noise is steady, match rhythm: thump means rollers, startup squeal means idler or belt, and lower-front rattle means lint path or blower.
Watch the timing. A thump at the same spot each drum turn usually points to a roller; first-minute squeal usually points to the idler or belt.
Use the sound, timing, and drum feel before ordering parts. Unplug the dryer before opening panels, and avoid disturbing the gas line.
Don’t start with: gas burner parts. Most dryer noises are mechanical, not fuel-system failures, and gas odor means stop instead of opening the cabinet.
If it thumps once per turn,look at drum rollers and flat spots.
If it squeals at startup,inspect the idler pulley and belt path with power off.
Do this first
- Unplug the dryer before removing any panel, belt, roller, or blower cover.
- If you smell gas, shut the dryer off, leave the area if needed, and call the gas utility or a qualified technician.
- Do not move a gas dryer far enough to strain the connector; close the gas shutoff first if safe and needed.
- Stop for burning smell, scorched lint, scraping metal, a drum that drops, or a damaged power cord.
- Let the dryer cool before reaching near the drum, burner area, or blower housing.
- Keep hands clear of the belt and drum path during any test run.
60-second noise sorter
Does it squeal or chirp at startup?
Suspect the idler pulley or belt path. Stop if the belt is frayed or the drum stops turning.
Does it scrape from the front or rear rim?
Inspect the felt seal, glide, and drum support area with the dryer unplugged.
Does it rattle near the lint screen or blower?
Look for coins, screws, lint chunks, or blower wheel damage before buying roller parts.
Does it rumble loudly with vibration?
Check leveling, load size, drum support, and blower wheel before replacing a control or gas part.
Any gas odor or burner boom?
Stop. Gas odor or unusual ignition is not a noise repair; use the gas utility or a qualified technician.
The sound points to the part area
Listen before opening the dryer. A steady thump, high squeal, scrape, or lint-path rattle leads to different parts.
Before you buy anything
Before buying rollers, an idler pulley, belt, felt seal, blower wheel, or motor, identify the noise pattern and copy the full model number. Keep the dryer unplugged for cabinet checks, and stop for gas odor, burned wiring, or rough ignition.
What is probably happening
Most LG front-load gas dryer noises are mechanical. Good clue: the dryer heats normally, but the sound repeats with drum rotation or comes from the lint/blower area.
- A thump once per drum revolution usually points to a worn drum roller or flat spot.
- A squeal that is worst at startup usually points to the idler pulley, belt path, or drum support friction.
- A scraping sound near the front or rear rim points toward a felt seal, glide, or drum support area.
- A rattle near the lint screen or lower front can be debris in the blower housing or a damaged blower wheel.
- Gas odor, rough ignition, or delayed burner lighting is a stop condition, not a roller or belt clue.
What not to do first
A noisy dryer can get worse if you run it until the belt breaks or the drum drops.
- Do not keep running the dryer if metal is scraping, the drum wobbles, or the belt smells hot.
- A thump, squeal, or scrape does not point to gas burner parts; gas odor or rough ignition means stop and call service.
- Do not move the dryer hard against the gas connector just to hear the noise better.
- Do not replace all moving parts at once unless a kit matches your model and multiple parts are visibly worn.
- Do not open the cabinet with power connected.
- Do not ignore lint buildup around the blower; it can cause rattles and heat risk.
Result map by sound
Run only a short listening test if the dryer is not scraping, smelling hot, or showing gas odor.
| Sound | Likely area | Next move |
|---|---|---|
| Thump once per drum turn | Drum rollers or roller shafts | Unplug the dryer and inspect rollers for flat spots, wobble, or rough rotation. |
| Sharp squeal or chirp | Idler pulley or belt path | Inspect idler pulley spin, belt wear, and belt routing before ordering. |
| Scrape from front or rear rim | Felt seal, glide, or drum support | Stop if metal is contacting metal; inspect the seal and support area with power off. |
| Rattle near lint screen | Loose object, lint chunk, or blower wheel | Check accessible lint path and blower housing; use service if cabinet access is beyond safe DIY. |
| Boom, gas odor, or rough ignition | Fuel or burner safety issue | Stop using the dryer and call the gas utility or a qualified technician. |
Check the drum support path
The drum rides on support parts. A good clue is a sound that repeats with drum rotation, not blower speed.
- Unplug the dryer and remove only the panels your model procedure requires.
- Turn each roller by hand and feel for wobble, grinding, flat spots, or a seized shaft.
- Inspect the idler pulley for rough spin, loose bracket, or belt dust nearby.
- Look for belt cracks, missing ribs, frayed edges, or a polished path that shows slipping.
- If the drum edge has been scraping, inspect the felt seal and glide area before running another load.
Check the blower and lint path
A rattling dryer is not always a roller. Good clue: the noise is lower front, near the lint screen, or changes with airflow.
- Remove loose lint from accessible areas around the lint screen housing and blower inlet.
- Look for coins, screws, buttons, or zipper pulls that slipped past the lint screen.
- Spin the blower wheel by hand only when power is disconnected and the wheel is accessible.
- If the blower wheel is cracked or loose on the motor shaft, match the replacement by model.
- Stop for scorched lint, melted plastic, or wiring damage around the lower cabinet.

Front drum seal or glide
Helps when: The drum edge scrapes and the felt seal is torn, bunched, worn through, or leaving lint at the rim.
Skip it when: The scrape is actually a loose object in the blower or a roller support problem.

Why is my LG front-load gas dryer making a thumping noise?
A thump that repeats once per drum turn usually points to a worn drum roller, flat spot, or roller shaft. Unplug the dryer before checking, and stop if the drum looks low or metal is scraping.
What causes a squealing LG gas dryer?
A sharp squeal at startup often comes from the idler pulley, belt path, or dry support parts. Unplug the dryer before checking the belt or idler.
Can a gas dryer noise be a burner problem?
Most thumps, squeals, scrapes, and rattles are mechanical. Gas odor, delayed ignition, or a boom is different; stop using the dryer and call the gas utility or a qualified technician.
Should I replace rollers and belt together?
Only if inspection supports it or a model-specific kit includes the worn parts. If one roller is flat-spotted, check the idler and belt while the cabinet is open.
What if the dryer rattles near the lint screen?
Look for loose objects, lint chunks, or blower wheel damage in the accessible lint path with power disconnected. Do not reach near the blower while the dryer is powered.
Can I keep running the dryer while it is noisy?
Not if it scrapes, smells hot, thumps hard, or the drum looks off-center. Continuing can break the belt, damage the drum support, or create a lint heat risk.
What part fixes a scraping dryer drum?
A torn felt seal, worn glide, or damaged support can scrape. Inspect the drum rim and seal area before buying parts because blower debris can sound similar.
Do I need to move the dryer to hear the noise?
Keep movement minimal. For basic listening, you usually do not need to move the connector; do not pull the dryer far enough to strain it, and use a qualified technician if the connector must move.
What should I copy before ordering dryer noise parts?
Copy the full model number, the sound pattern, and the worn part dimensions or layout. Roller shafts, idler brackets, belt length, and seal positions vary.
