Quick answer

If your LG front load gas dryer is making noise, start by checking for loose objects in the drum and cleaning the lint filter. If the noise continues, inspect the drum rollers or idler pulley, which are common sources of unusual sounds. Turn off the dryer before troubleshooting.

Confirm the symptom

Dryer makes loud noise during operation
Noise is rhythmic or grinding
Noise occurs only when the drum rotates

Tools and prep

Screwdrivers (flathead and Phillips)
Flashlight
Work gloves
Lint brush or vacuum
Owner’s manual
Turn off power at the circuit breaker or unplug the dryer

Step-by-step troubleshooting

Check for Foreign Objects
Do: Inspect the drum and lint filter for loose coins, buttons, or debris.
Observe: Noise stops after removal of objects
Means: Noise was caused by foreign objects
Next: If noise persists, move to next step
Clean Lint Filter and Vents
Do: Clean the lint filter and use a vacuum to clear vent ducts.
Observe: Noise decreases or stops
Means: Clogged vents caused airflow issues
Next: If noise continues, inspect drum rollers
Inspect Drum Rollers
Do: Remove the front panel and check drum rollers for wear or damage.
Observe: Rollers are worn or wobbling
Means: Faulty drum rollers cause noise
Next: Replace damaged rollers
Check Idler Pulley
Do: Locate the idler pulley near the drum and test for smooth rotation.
Observe: Pulley is noisy or stiff
Means: Worn idler pulley needs replacement
Next: Replace the idler pulley
Examine Drive Belt
Do: Check the drive belt for cracks or looseness.
Observe: Belt is damaged or loose
Means: Drive belt issues can cause noise
Next: Replace the drive belt
Test Motor Mounts
Do: Inspect motor mounts for looseness or damage.
Observe: Mounts are loose or broken
Means: Loose motor mounts can cause vibration and noise
Next: Tighten or replace mounts

Common causes

Cause	Likelihood	Difficulty	Part often needed
Foreign Objects in Drum Loose items can hit the drum or drum wall, creating noise.	Common	Easy	None
Clogged Lint Filter or Vents Restricted airflow can cause motor strain and noise.	Common	Easy	None
Worn Drum Rollers Rollers support the drum; worn ones create noise when rotating.	Common	Medium	Drum Rollers
Faulty Idler Pulley The pulley maintains belt tension; wear causes grinding or squealing.	Sometimes	Medium	Idler Pulley
Damaged Drive Belt A cracked or loose belt can slip and create noise.	Sometimes	Medium	Drive Belt
Loose or Broken Motor Mounts Mounts absorb vibration; failure causes excessive noise.	Rare	Hard	Motor Mounts

FAQ

Can I fix the noise without opening the dryer?

Yes, start by removing foreign objects and cleaning the lint filter. If the noise stops, no further action is needed.

How do I know if the idler pulley is bad?

A worn idler pulley may make a grinding or squealing noise when the dryer runs. Spin it manually to check for smooth rotation.

Is it safe to replace parts myself?

Yes, if you follow safety steps like turning off power. However, consult a professional if you're unsure about gas or electrical connections.

Why does my dryer make noise only when drying?

Noise during drying could indicate a clogged vent or motor strain. Check vents and ensure proper airflow.
