You could argue that dryers are the most underrated appliance purchase — everyone obsesses over the washer and then picks whatever dryer matches. But a bad dryer over-dries clothes, wastes energy, and shortens fabric life. The LG DLEX4000W and Samsung DVE45R6100C are the front-runners in the $700–$900 electric dryer category, and the differences between them are worth knowing before you commit.
LG DLEX4000W
The LG DLEX4000W has more accurate moisture sensing and better fabric care; the Samsung DVE45R6100C is quicker on large loads and slightly cheaper.

Sensor Drying: The Feature That Actually Matters
Both machines advertise sensor drying, but Consumer Reports has consistently found LG's sensor accuracy ahead of Samsung's in blind testing. The LG DLEX4000W's sensor stops the cycle more precisely — clothes come out damp-dry rather than either bone-dry-and-hot or slightly damp. Over thousands of cycles, that precision extends fabric life meaningfully.
Samsung's DVE45R6100C sensor works well on average loads but shows more variance on very large loads — a drum stuffed with thick towels can fool the sensor into stopping early. This is a known limitation that Samsung has addressed only partially across model generations.
Both machines have 'Damp Alert' features that notify you when clothes are at ironing-ready moisture levels. LG's implementation is more consistent in Consumer Reports' testing.
Capacity, Cycles, and Steam
Both the LG DLEX4000W and Samsung DVE45R6100C offer 7.4 cu ft drums — the standard large-capacity size for American households and plenty of space for a king comforter. LG's drum has a slightly larger door opening, which makes loading and unloading bulky items easier, though this is a minor ergonomic point.
LG includes a steam refresh cycle that can de-wrinkle a dress shirt in about 20 minutes without a full dry cycle. Owners on r/Appliances call this one of the most genuinely useful dryer features — skip the ironing for lightly worn items. Samsung offers a similar 'Steam Sanitize+' feature on this model.
Cycle count: LG offers 14 preset cycles to Samsung's 10. The practical difference is small since most people use 3–4 cycles regularly, but LG's 'Delicates' and 'Activewear' presets are better calibrated.
Noise, Smart Features, and the App Experience
LG rates the DLEX4000W at 55 dBA, and real-world owner reports align with that figure. Samsung's DVE45R6100C is slightly quieter at ~52 dBA — both are unobtrusive in a closed laundry room but audible in an adjacent living space.
LG's ThinQ AI app integration is more feature-rich: you get cycle notifications, remote start, and the Smart Diagnosis tool that sends error codes directly to LG support without you having to describe the problem. Samsung's SmartThings integration is comparable in basic functionality but historically less reliable for maintaining persistent background connections.
Neither machine requires any smart features to work well — the app is genuinely optional, not mandatory. But LG's implementation is the more polished product.
Reliability and Total Cost
Yale Appliance data shows LG electric dryers have a lower service rate than Samsung's across their respective front-load-paired models. The DLEX4000W specifically shows up well in first-year service data. Samsung's DVE45R6100C is reliable but trails LG on this metric.
The LG DLEX4000W MSRP is $799. Samsung's DVE45R6100C lists at $749. Both go on sale regularly, and you can often find either under $650 during holiday sales. The $50 price difference is not a meaningful factor at this quality level.
Over a 10-year ownership horizon, LG's energy efficiency advantage and sensor accuracy genuinely matter — expect slightly lower electricity bills and clothes that last longer. That's the buy-it-once argument for paying the small premium.
LG DLEX4000W Strengths
- More accurate moisture sensing per Consumer Reports — stops cycles at the right moment more consistently
- Steam refresh cycle de-wrinkles lightly worn items in 20 minutes
- Lower service rate in Yale Appliance reliability data for matched LG pairs
Samsung DVE45R6100C Strengths
- Slightly quieter operation at ~52 dBA vs LG's 55 dBA
- Lower MSRP ($749 vs $799) with competitive sale pricing
- Steam Sanitize+ cycle kills 99.9% of bacteria and viruses — useful for gym clothes and children's items
LG DLEX4000W Weaknesses
- Rated 55 dBA — slightly louder than Samsung on spin cycles
- Door hinge occasionally reported as stiff by owners in the first 6 months of use
- LG app has known issues maintaining connection on 2.4 GHz-only routers
Samsung DVE45R6100C Weaknesses
- Sensor accuracy varies on large dense loads — thick towels can trigger premature stop
- Higher first-year service rate than LG's matched model per Yale Appliance data
- SmartThings app connectivity drops reported more frequently than LG's ThinQ
Best For
- a: Fabric-conscious households, anyone pairing with an LG washer for matched reliability, or buyers who want precise sensor performance
- b: Budget-focused buyers, households with small children who need Steam Sanitize, or anyone who prioritizes quiet operation
FAQ
Do I have to buy the same brand washer and dryer?
No — any dryer can pair with any washer electrically. However, stacking requires brand-matched models and a specific stacking kit. If you're stacking, buy the same brand. Side-by-side installations can mix brands freely.
Is 7.4 cu ft big enough for a king comforter?
Yes, for most king comforters. Very thick down comforters may need a commercial dryer at a laundromat for best results, but standard cotton-fill or synthetic king comforters dry well in a 7.4 cu ft drum. Don't overstuff — items need space to tumble.
How often should I clean the lint trap?
After every load — always. Both machines have standard slide-out lint screens that take 5 seconds to clean. Beyond that, vacuum the lint trap housing every 6 months and have the exhaust duct cleaned every 2–3 years to prevent fire risk.
