Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: DLHC5502*
What that covers: Ventless heat-pump dryer; lint filters, condenser airflow and water drainage differ from vented dryers.

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 — VENTLESS HEAT-PUMP (no vent at all): A 7.8 cu. ft. VENTLESS heat-pump dryer (DLHC) — it recirculates and reheats air with a heat pump instead of venting hot air outside, using up to ~65% less energy. There is NO exhaust duct, so 'not drying' is never a blocked vent; it is a condenser/lint or refrigeration question. It also dries at a LOWER temperature, so clothes come out warm, not hot, and cycles run longer than a vented dryer — that is normal.
Condenser & lint maintenance: Instead of a vent it has lint filters AND a condenser; this model has an Auto Cleaning Condenser, but the lint filters still need cleaning every load, and a gradually poorer dry is almost always lint/condenser buildup, not a heater fault. It condenses moisture to a drain or tank — a full tank (if not plumbed to a drain) stops it.
Install & power: Ventless means flexible install (closet, interior wall). It runs on 240V, with DirectDrive and AI Sensor Dry.

Exact questions

Questions that only have an answer for the LG DLHC5502 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 LG DLHC5502 heat-pump dryer takes forever / clothes come out warm not hot.+

That is normal for a heat-pump dryer. It dries at a much lower temperature than a vented dryer to save energy, so clothes feel warm rather than hot and cycles legitimately take longer. If drying is getting worse over time, clean the lint filters every load (there are usually two) and check the condenser — lint buildup there is the top cause. Also confirm the condensate drain or water tank is clear, since a full tank halts the cycle. There is no vent to check, because it is ventless.
