What Does Error D75 Mean?

The LG dryer D75 error indicates a significant ventilation airflow restriction, approximately 75% blockage. This issue typically results in longer drying times and reduced airflow at the vent or exhaust. The primary causes include a restricted dryer vent, a clogged lint screen, or potentially a faulty vent sensor or thermistor. Immediate attention is required to restore proper airflow and prevent further damage to your dryer.

Common Symptoms:

  • Dryer displays D75 on control panel
  • Longer drying times noted
  • Reduced airflow at vent/exhaust

Possible Causes

  • Restricted dryer vent/airflow blockage (medium)
  • Clogged lint screen contributing to airflow restriction (medium)
  • Faulty vent sensor or thermistor reporting air-flow conditions (low)
