| 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. |
| F4 E4Also F4E4, L2 | Low or missing line voltageWhirlpool says F4 E4 can mean the electric dryer is not receiving the full line voltage its heater requires. The drum may still turn even when one side of the supply is unavailable. | Service recommended | Stop the dryer and identify its dedicated paired breakers without opening the appliance. |
| dCAlso dE, dF, do, d0, 1 dC, 1 dF | Door, latch, or door-sensor errorSamsung groups dC with door-related dryer codes. The door may not be closing securely, laundry may be trapped, or the latch or sensor may be damaged. | Check now | Stop the dryer and remove the load from the door opening. |
