Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Type — COMPACT VENTLESS HEAT-PUMP
- A compact 4.2 cu. ft. VENTLESS heat-pump dryer (DLHC) for small spaces — recirculates and reheats air, no exhaust duct. 'Not drying' is a condenser/lint or full-tank question, never a blocked vent. It dries at low temperature (clothes warm, not hot) and takes longer than a vented dryer, which is normal.
- Compact + condenser maintenance
- Small drum means small loads — overloading badly hurts drying because heat-pump drying needs room to tumble. Clean the lint filters every load and the condenser regularly; buildup is the top cause of gradual drying loss.
- Install & power
- Ventless and compact, so it installs almost anywhere, often on a standard 120V outlet — no 240V or duct needed.

Questions that only have an answer for the LG DLHC1455 compact heat-pump dryer
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
My compact LG DLHC1455 dryer leaves clothes damp.+
Two causes dominate on a compact heat-pump dryer: overloading and maintenance. Dry small loads — a compact heat-pump needs room to tumble, and stuffing it in leaves clothes damp. Clean both lint filters every load and the condenser regularly, and empty the water tank (or confirm the drain) since a full tank stops drying. Remember it dries cool and slow by design, so warm, slower results are normal, not a fault.
Structured depth, not empty permutations
