LG Dryer Tips & Maintenance Guide
55 tips from certified technicians — keep your LG dryer running safely and efficiently for 10–15 years.
Maintenance
Routine care that keeps your LG dryer running at peak performance.
Clean the lint filter after every single load
This is the single most important maintenance habit. A clogged filter restricts airflow, increases drying time, raises energy costs, and is the leading cause of dryer fires. Lift it out and clean by hand or with a vacuum.
Wash the lint filter with water once a month
Fabric softener and dryer sheet residue coats the mesh and restricts airflow even when the filter looks clean. Scrub with a soft brush under warm water monthly, then let it dry completely before reinserting.
Wipe the moisture sensor regularly
The two metal sensor bars inside the drum (behind the lint filter) collect fabric softener residue over time. This causes inaccurate drying times or the dryer shutting off too early. Wipe with a dry cloth or cotton ball dipped in rubbing alcohol.
Clean the full exhaust duct at least once a year
Lint accumulates throughout the entire duct length — not just at the opening. Use a dryer vent cleaning kit with a rotating brush. If your duct run exceeds 9 feet, clean it more frequently. Extended drying times are the first sign of a clogged duct.
Inspect the door gasket for wear
Check the door seal for tears, lint buildup, or hardening. A damaged gasket allows heat to escape, reducing efficiency. Clean it with a damp cloth and replace if you notice visible cracks or the door doesn't seal tightly.
Lubricate moving parts every 6 months
Drum rollers, idler pulley, and bearings benefit from periodic lubrication with manufacturer-approved lubricant. This prevents squealing, reduces motor strain, and extends the life of internal components. Use only non-flammable lubricants.
Schedule professional service once a year
Annual professional maintenance — cabinet opened, drum removed, interior cleaned of accumulated lint — directly reduces fire risk and extends the unit's lifespan. Lint buildup deep inside the cabinet is invisible from the outside.
Check the exhaust duct material
If your duct is plastic or foil accordion-style, replace it with rigid metal ducting. Plastic ducts sag, trap lint at low points, and are a leading cause of dryer fires. Rigid metal has smooth walls that allow airflow and resist lint buildup.
Check the outdoor vent flap seasonally
The flap should open freely when the dryer runs and close completely when it stops. Check it for lint blockage, bird nests, or debris — especially after fire season and winter. A stuck flap traps hot air inside and creates a fire hazard.
Make sure leveling legs are properly adjusted
The unit should sit flat and stable — not rock or vibrate on the floor. Uneven legs cause excessive vibration that accelerates wear on the drum bearings, rollers, and motor. Adjust all four legs and check with a level.

Fire Safety
Dryers cause ~16,000 home fires per year in the US. These tips keep your home safe.
Never run the dryer when you leave home or go to sleep
If a fire starts while no one is present, the damage can be catastrophic. Always run the dryer only when someone is home and awake. This single rule prevents most dryer fire fatalities.
Never dry clothes soaked in flammable chemicals
Gasoline, cooking oil, paint thinner, acetone — even after washing, the residue can remain in the fabric. The heat of the dryer can ignite these chemicals. Hang such items outside to air dry completely before machine drying.
Keep 36 inches of clear space around the dryer
Never store boxes, cleaning supplies, clothing, or paper products near the dryer. Lint is highly flammable and any nearby combustibles can ignite. The laundry area should be kept clean and uncluttered at all times.
If you smell burning — stop immediately
Turn off and unplug the dryer at once. Do not continue running it. A burning smell indicates lint buildup, a failing component, or electrical issue. Call a technician to inspect the unit for fire hazards before using it again.
Never operate the dryer without the lint filter installed
Running the dryer with the filter missing allows lint to travel directly into the exhaust duct and internal components — dramatically increasing fire risk. Always confirm the filter is seated before starting a cycle.
Have working smoke alarms in and near the laundry room
Install a smoke detector in or adjacent to the laundry area and test it monthly. Dryer fires often start inside the duct system and produce smoke before open flame — an alarm gives you critical early warning.
Check the duct isn't kinked or crushed behind the unit
When the dryer is pushed close to the wall, the flexible duct section at the back can kink or compress. This blocks airflow completely — the same as a clogged vent — and creates a serious fire and overheating risk. Leave adequate clearance.
Never dry mop heads in the dryer
Mop heads often contain cleaning chemical residue that can ignite under dryer heat. Always air dry mop heads outside or in a well-ventilated area. This applies to any item that has been in contact with cleaning agents.

Fabric Care
What to dry, what to air-dry, and how to protect your clothes.
Always read the care label before drying
The care label is the definitive guide for each garment. Some items marked "dryer safe" still require low heat. Some items say tumble dry but mean low heat only. Two minutes reading labels prevents permanent fabric damage.
Never put wool, cashmere, or silk in the dryer
Heat causes wool fibers to contract permanently — often shrinking garments to unwearable sizes in a single cycle. Silk loses its luster and texture under heat. Always lay these items flat on a rack to air dry.
Don't dry activewear and sportswear on high heat
Elastic fibers in workout clothes are slowly destroyed by heat. After several cycles, your favorite gear loses its stretch permanently. Use low heat or the delicate cycle, or air dry activewear on a rack.
Never put bath mats with rubber backing in the dryer
Rubber backing can melt, separate, and create a fire hazard inside the drum. Hang bath mats in a sunny spot to air dry. For rugs with latex or foam backing, always air dry — never machine dry.
Don't dry clothes with sequins, beads, or metal embellishments
The tumbling action and heat can dislodge decorations, damage the drum interior, and snag other garments. Always air dry embellished items flat, away from direct sunlight.
Never put footwear in the dryer
The heat separates rubber soles from uppers, melts adhesive, and deforms performance fabrics. Stuff damp shoes with newspaper to absorb moisture and air dry away from heat and sunlight.
Use delicate/low-heat for linen, rayon, and cotton knits
Natural linen can shrink significantly on high heat. Rayon and Lycra lose shape and pill. Cotton knits stretch out of shape when tumbled hot. Low heat takes a few minutes longer but preserves the garment's original fit and feel.
Sort laundry by fabric weight before drying
Dry towels and heavy cotton separately from lightweight synthetics. When mixed, light items over-dry and get damaged while heavy items stay damp. Separating by weight gives every garment the exact drying time it needs.
Shake and untangle clothes before loading the dryer
Tangled clothes trap moisture pockets and dry unevenly. Taking a few seconds to separate and shake each item before loading reduces drying time and prevents wrinkles from setting in twisted fabric.
Put socks in a mesh laundry bag
All your socks go in a zipped mesh bag before washing — the bag goes in the dryer too. When you take it out, all socks are still paired. Simple system, zero lost socks.
Energy Savings
Simple habits that cut your electricity bill and extend the dryer's lifespan.
Always use Auto Dry instead of a timed cycle
The moisture sensor automatically stops the cycle the moment clothes are dry — not a minute longer. Timed cycles over-dry, which wastes energy, damages fabric fibers, and creates static cling. Auto Dry is better in every way.
Use the highest spin speed in the washer first
The more water extracted in the wash cycle, the less work the dryer has to do. Maximizing the washer's spin speed can cut dryer time by 20–30% — this is the cheapest energy-saving upgrade available.
Dry loads back to back
The drum is already hot from the previous load — starting the next load immediately takes advantage of residual heat. Waiting hours between loads means the dryer has to heat up from cold each time, using significantly more energy.
Use low heat when you're not in a rush
Modern LG dryers dry most loads on low heat just as effectively as high heat — it takes slightly longer but uses measurably less energy and is far gentler on fabric fibers. High heat is for towels and heavy cotton only.
Use the cool-down cycle
If your LG dryer has a cool-down or wrinkle-care cycle, use it. It finishes drying clothes using only the heat already in the drum — zero additional energy for the final minutes of the cycle.
Add a dry towel to cut drying time
Toss one clean, dry bath towel in with a wet load. The towel absorbs extra moisture and can reduce drying time by up to 20 minutes. Remove the towel after 15–20 minutes and continue the cycle with the original load.
Don't underload — wait for a full load
Running the dryer for 3 items uses nearly the same energy as a full load. Wait until you have a reasonable load — aim for about two-thirds of the drum capacity. Too full restricts airflow; too empty wastes energy per garment dried.
If your dryer takes longer than usual to dry — it's likely a vent or sensor issue. We can fix it same day.
Steam Function
How to use LG's steam cycles correctly — and what to do if water is leaking.
Does your LG dryer have a steam function?
LG steam dryers inject hot steam into the drum to refresh fabrics, remove wrinkles, and sanitize without a full wash cycle. The steam system connects to your home water supply via a dedicated hose, or uses a manual refillable reservoir depending on the model.
✅ When steam is useful
Use Steam Fresh to refresh lightly worn clothes
Dress shirts, blazers, trousers, and jackets that don't need a full wash can be freshened in 20–30 minutes with the Steam Fresh cycle. It removes odors and reduces wrinkles without water, detergent, or a full drying cycle.
Use Steam Sanitary for pillows and non-washable items
Throw blankets, stuffed animals, pillows, and dry-clean items can be sanitized with the Steam Sanitary cycle. High-temperature steam kills 99.9% of common bacteria and dust mites without water or chemicals.
Steam reduces static cling during regular cycles
Even on standard dry cycles, LG's steam generator injects a small burst of steam in the last 15 minutes to reduce static. If clothes feel slightly damp at the end of a normal cycle — this is normal, not a malfunction.
❌ When NOT to use steam
Never use steam on wool, silk, nylon, or lace
Steam heat permanently damages delicate fabrics — causing shrinkage, discoloration, and texture loss. The Steam Fresh and Steam Sanitary cycles are designed for cotton, cotton-polyester blends, and common knits only.
Don't use steam on freshly washed wet clothes
Steam cycles are designed for dry clothes only. Loading damp or wet items will result in clothes that are still wet at the end of the cycle. The cycle works by refreshing — not drying — so start with completely dry garments.
Don't overload the steam cycle
Maximum 3–5 garments for Steam Fresh. When the drum is too full, steam can't circulate between items and the cycle won't work effectively. Group similar fabrics together for best results.
Remove dryer sheets before using steam
Fabric softener residue on dryer sheets can cause temporary staining when combined with steam heat. Always remove any dryer sheets from the drum before selecting a steam cycle.
🔧 Steam maintenance tips
Fill the reservoir with regular tap water only
Use regular filtered tap water — not distilled, not reverse osmosis. Distilled water lacks the minerals that the water level sensor needs to detect the fill level. The steam feeder must be filled to the MAX line before starting.
Clean the steam reservoir regularly
Mineral deposits from tap water gradually clog the steam nozzle and reduce output. Rinse the reservoir with a mild white vinegar solution every few months to dissolve calcium buildup and keep steam generation strong.
⚠️ Water leaking from your steam dryer?
Water coming from a steam dryer is always abnormal and should be addressed immediately. Here's how to identify the source:
Turn off the water supply immediately. Disconnect the hose from both ends and reconnect firmly. Check for cracks in the hose and replace rubber washers at both ends. If leaking continues, the wall faucet or water pressure may be too high — call a plumber.
Stop the dryer immediately. This usually indicates a faulty water inlet valve, cracked steam generator housing, or damaged spray nozzle inside the drum. Do not continue running the unit — call a technician for diagnosis.
On ventless/condensing models, a blocked or kinked drain hose prevents condensate from draining. Check that the drain hose trails naturally to the drain without kinks. The drain height should be no more than 1 meter (3.3 ft) from the dryer's base.
Internal steam generator leaks, inlet valve failures, and condensate pump issues require professional diagnosis. Our technicians serve LA County, Orange County, and Ventura County — same day.
(323) 990-7550Pro Hacks
Clever tricks from laundry professionals that most people don't know.
Ice cubes remove wrinkles without an iron
Clothes came out wrinkled? Toss 2–3 ice cubes in the drum with the dry clothes and run on high heat for 5 minutes. The melting ice creates steam that relaxes fabric fibers — no iron required. Works best on cotton and blends.
Crumpled aluminum foil eliminates static
Ball up a sheet of aluminum foil and toss it in the dryer with any load. It neutralizes static buildup on synthetic fabrics naturally. One ball lasts for months — a completely free alternative to dryer sheets with no chemical residue.
Wool dryer balls — better than dryer sheets
Wool or rubber dryer balls separate clothes, improve airflow, reduce static, shorten drying time, and add softness — without leaving residue on the moisture sensor like fabric softener does. They're reusable for hundreds of loads.
Fold clothes immediately while still warm
Remove clothes from the dryer the moment the cycle ends and fold or hang them right away. Clothes stay wrinkle-free for much longer when folded warm. Leaving them in the drum for even 15 minutes sets in wrinkles that are hard to shake out.
Tennis balls fluff pillows and comforters
Add 2–3 clean tennis balls when drying pillows, comforters, and fluffy coats. They bounce around and break up clumps, redistributing the filling evenly for a properly fluffy result. Dryer balls work the same way.
Over-drying is the #1 cause of static cling
Static builds up when fabric loses all its moisture. Using Auto Dry prevents this automatically. If you use a timed cycle, set it slightly shorter than you think you need — clothes can finish air drying for the last few minutes outside the drum.
Sounds, Smells & Warning Signs
What different symptoms mean and when to call a technician.
Grinding or squealing — stop and call immediately
Mechanical noise almost always means worn drum rollers, a failing idler pulley, or a worn drum bearing. Continuing to run the dryer spreads damage to the motor, belt, and drum. Catching it early means a $200–350 repair instead of $500+.
Thumping sound — check for foreign objects first
A rhythmic thumping often means a coin, button, or small object bouncing in the drum or caught in the drum seal. Check pockets before every load. If the drum is empty and thumping continues, it's likely worn drum rollers.
Clothes taking longer than usual to dry
Extended drying times are the first and most reliable symptom of a clogged exhaust duct. Check that the outdoor vent is blowing air freely while the dryer runs. If not — the duct needs cleaning. Don't ignore this symptom.
Check pockets before every single load
Coins damage the drum and create thumping. Pens leave permanent ink stains. Gum and candy melt onto the drum interior. Lip balm and chapstick grease the drum and transfer to all clothing. 30 seconds checking pockets prevents all of these.
Always check inside the drum for pets before starting
Cats and small pets are attracted to warm, enclosed spaces. They can climb inside through an open door while you're not watching. Before starting any cycle, look inside the drum. This is not a joke — it happens more often than people expect.
