LG DLEX3470V dryer Parts

The LG DLEX3470V dryer typically sold new for about $1,200 MSRP; your actual price depends on the retailer, finish, promotions, and whether you’re buying new, open-box, or used. For model identification details, check the DLEX3470V owner's manual.

Prices vary a lot by condition and seller. Use these ranges as a practical shopping guide:

• New (when available): often near MSRP, sometimes lower during promotions
• Open-box: usually discounted versus new
• Used: depends heavily on age, hours of use, and local demand
• Delivery/haul-away: can add to the total
• Installation parts: venting, cord, and clamps may be extra

A dryer’s “real” cost is the purchase price plus any immediate fixes or setup needs.

• Confirm the exact model number DLEX3470V on the rating label
• Verify it heats and tumbles smoothly (no squeal or thump)
• Check airflow; poor venting can cause long dry times
• Inspect wear items like the drum belt and rollers if it’s used
• Budget for common maintenance parts if performance is questionable

Paying a little more for a properly functioning dryer can prevent repeat service calls and premature wear on key components like the belt, idler pulley, and heating system.

Most LG dryers, including model DLEX3470V, typically last 10 to 15 years with normal household use and basic maintenance. Lifespan is driven less by the brand name and more by airflow (lint and venting), load size, and how quickly worn parts are replaced; see the DLEX3470V owner's manual for care and cleaning guidance.

• Vent restriction (lint buildup, crushed duct, long duct runs) increases heat and wear
• Overloading strains the drum support system and belt
• Skipping lint cleaning reduces airflow and can overheat components
• High-heat cycles all the time accelerate wear on thermostats and the heating system
• Delayed repairs (squeals, thumps, burning smell) often turn small issues into major ones

• Clean the lint screen every load; wash the screen film off periodically if you use dryer sheets
• Check airflow at the outside vent hood; strong, steady exhaust matters
• Clean the vent duct at least yearly (more often with pets or heavy use)
• Keep the dryer level to reduce vibration and drum wear
• Stop using the dryer if you hear loud squealing or grinding; inspect wear parts

A dryer that is venting poorly can run hotter and longer, which shortens the life of the heating system, thermostats, motor, and drum support parts. Good airflow and prompt replacement of wear items usually deliver the full 10 to 15 year service life.

The most common problem we see with LG dryers like model DLEX3470V is poor drying performance: clothes take too long to dry or the dryer does not heat properly. In most cases, restricted airflow (lint buildup in the venting) is the root cause; failed heating or safety components are the next most common.

• Clogged or crushed exhaust vent, blocked exterior hood, or lint buildup in the blower housing
• Heating system issues (electric models): open heating element or a thermostat that is tripping
• Overheating protection opening due to airflow restriction (high-limit thermostat)
• Moisture sensor bars coated with residue, causing Auto cycles to end early
• Drum not tumbling normally (belt, idler pulley, rollers), which reduces drying efficiency
• Door switch or control sensing issues that interrupt operation

1. Clean the lint screen and confirm strong airflow at the outside vent while the dryer runs.
2. Inspect the vent path for kinks, long runs, or heavy lint; clean the full duct to the exterior.
3. If the drum turns but there is no heat, test the heating circuit components.
4. If Auto cycles end too soon, wipe the moisture sensor bars with rubbing alcohol.
5. If you hear squealing, thumping, or the drum will not turn, inspect the belt and drum support parts.

Airflow problems do more than slow drying; they also raise operating temperatures, which can trip thermostats and shorten the life of parts like the heating element, belt, and drum support components.
