A LG dryer taking too long to dry is most often an airflow problem, not an immediate heating-element failure. Start with the lint screen and exterior vent before checking settings or arranging service.
Safety first: Unplug the dryer before moving it or inspecting duct connections. For gas dryers, leave the area if you smell gas.
Normal Behavior vs. a Problem
A mixed load, bulky towels, low-heat cycle, or sensor cycle ending early can make drying time vary. Two or more normal cycles for a small load, weak outside airflow, or excessive heat in the laundry room is not normal.
Common Causes
1. A lint screen is clogged or coated with residue from dryer sheets.
For LG appliances, use the full model number when checking the manual because panel messages, filter access, and diagnostic procedures can vary by series.
2. The transition hose is crushed, too long, or made of unsafe flexible material.
For LG appliances, use the full model number when checking the manual because panel messages, filter access, and diagnostic procedures can vary by series.
3. The wall duct or outside hood is restricted by lint or debris.
For LG appliances, use the full model number when checking the manual because panel messages, filter access, and diagnostic procedures can vary by series.
4. The cycle, temperature, load size, or sensor use is not appropriate for the load.
For LG appliances, use the full model number when checking the manual because panel messages, filter access, and diagnostic procedures can vary by series.
5. A heating, moisture-sensing, blower, thermostat, or gas-ignition component is faulty.

Safe Step-by-Step Troubleshooting
Step 1
Clean the lint screen before every load and wash it with mild soap if water beads on it.
Step 2
Use a timed high-heat test with a normal-sized load, following the garment labels.
Step 3
Unplug the dryer, pull it forward carefully, and inspect for a crushed exhaust hose.
Step 4
Check that the outdoor hood opens while the dryer runs; do not reach into a moving hood.
Step 5
If airflow is weak, stop repeated use and arrange vent cleaning.
Step 6
If airflow is strong but heat is intermittent or absent, have internal parts tested with power disconnected.
Components That May Be Involved
Lint screen, moisture sensors, blower wheel, exhaust duct, heating element or gas burner components, thermal fuse, thermostat, and control board.. Part numbers and test values are model-specific, so do not replace a part based only on a symptom.
When to Call a Professional
Call a qualified technician if the symptom returns after the safe checks, the appliance trips a breaker, leaks, smells hot or burnt, loses cooling or heat, or needs internal electrical, sealed-system, gas, or disassembly work.
