What to Check First

  1. Users will be alerted by an alarm if the exhaust pipe leading outside is clogged since it will affect the dryer's air flow and drying effectiveness.
  2. If the exhaust pipe blockage lights come on.
  3. Airflow in the Dryer is poor and the drying time is extended.
  4. When the exhaust pipe blockage light comes on and d90 / d95 error appears.
  5. Even with the maximum drying time, clothes may not dry, so it ends the drying cycle automatically and drying ceases.
  6. Move left or right to check the contents.
  7. If the filter is clogged with lint, the warm air cannot escape, making it difficult to dry clothes properly and thereby lengthening the drying time. Make sure the filter is clean.
  8. If the filter is clean but the exhaust pipe blockage light still comes on, the problem is in the exhaust pipe, not inside the dryer. The exhaust pipe may be clogged with lint, or the exhaust pipe may be kinked, preventing air from flowing out smoothly. Request an in-house service for an exhaust pipe inspection by an LG service technician.
  9. The air volume sensor precisely checks and reflects the 2nd and 3rd programs. The cleaning may not be reflected after cleaning the exhaust pipe. However, if the blockage in the exhaust pipe indication does not clear even after cleaning and drying, we recommend a service inspection.
