Safe first steps, before the call. Nothing here needs a tool.
If you smell gas: don’t touch any switch or plug, leave, then call the gas company or 911 from outside.
No gas smell? Note what the noise sounds like and when it happens, then stop the dryer and switch off its breaker, or unplug it if the plug is dry and you can reach it without moving the dryer.
Take a photo of the dryer and any code on the display, without opening anything.
Everything else about this problem
Is it an emergency?
Is a loud noise from an LG dryer an emergency?
Usually not an emergency. A grinding, rattling or humming that has just started most often comes from a fan, motor, belt or loose panel. Stop using it and cut the power if the noise comes with a burning smell, smoke or sparks; if it runs on gas and you smell gas, leave and call the gas company or 911 from outside.
Symptoms & causes
Loud noises from an LG dryer can manifest as squealing, grinding, thumping, or rattling sounds, often intensifying during the drum's rotation. These noises commonly stem from worn-out mechanical components such as the idler pulley, drum rollers, or a failing drive motor. Foreign objects caught in the blower wheel or between the drum and housing can also produce significant noise.
Tools & parts
Essential tools for checking and repairing loud LG dryer noises include Phillips and flathead screwdrivers, nut drivers, and possibly pliers for various fasteners. Specific replacement parts often needed are an LG drum roller kit, an idler pulley assembly, or a new drive belt. A shop vacuum is also useful for cleaning out accumulated lint and debris during the repair process.
Safety first
Always ensure the LG dryer is completely disconnected from its power source by unplugging it or turning off the dedicated circuit breaker before attempting any inspection or repair. Be cautious of sharp metal edges inside the dryer cabinet and the potential for electrical shock if power is not properly isolated. Allow the dryer to cool down completely if it has recently been in operation, as internal components like the heating element can remain very hot.
When to call a pro
If the dryer's main drive motor is emitting a loud grinding or humming noise and struggling to turn the drum, it often indicates internal bearing failure which is a complex and costly repair best handled by a professional. Persistent error codes on the control panel, especially those related to motor or sensor malfunctions on advanced LG models, typically require a technician's testing tools and expertise. Severe damage to the blower wheel housing or a deeply lodged foreign object that is difficult to access without specialized tools might also warrant professional intervention.
Questions people ask
Why does my LG dryer make a squealing noise?
A squealing noise in an LG dryer often indicates a worn idler pulley or failing drum rollers that need lubrication or replacement. These components support the drum and belt, and wear can cause friction and high-pitched sounds.
What causes a thumping or banging sound in my LG dryer?
Thumping or banging usually points to worn drum rollers or glides, or potentially a foreign object caught between the drum and the housing. Inspect the drum support system and carefully check for any loose items.
Can a loose drive belt cause loud noises?
Yes, a loose or frayed drive belt can slip and cause squealing or thumping noises as it struggles to turn the drum. Inspect the belt for cracks, fraying, or proper tension, and replace it if it shows signs of wear.
