| Code | What it means | Urgency | First safe check |
|---|---|---|---|
| d80Also D80, Flow Sense d80 | Restricted exhaust airflowLG groups d80 with its Flow Sense airflow warnings. The restriction can be at the lint filter, the short connector behind the dryer, the exterior outlet, or farther inside the home vent. | Pause and inspect | Stop the cycle and let the dryer cool before checking the airflow path. |
| d90Also D90, Flow Sense d90 | Severe exhaust airflow restrictionLG lists d90 in the same Flow Sense family as d80 and d95. Treat a returning d90 as an unresolved exhaust-path problem, not as a display fault that should be cleared repeatedly. | Pause and inspect | Stop the cycle and allow the appliance and load to cool. |
| tE1Also TE1, tE 1 | Thermistor reading problemLG says tE1 means the dryer detected a problem with its thermistor, the sensor used to read temperature. LG provides one controlled power reset before repair is recommended. | Service recommended | Stop the dryer and let it cool. |
How to use this index
Copy the display exactly
Spaces, letters, and lookalike characters matter. For example, 5E and SE may be easy to confuse on a segmented display.
Confirm the exact model
Error meanings and access instructions can vary by product family and model revision, even within one brand.
Start with observable checks
A code points to a system. It does not prove which part failed, so compare the symptom before replacing anything.
