If the exact code is not listed, use the model manual rather than assuming a similarly named code means the same thing.
| 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. |
| PFAlso Power Failure, PF error | Power failure interrupted the cycleWhirlpool says PF appears when a power failure interrupts the drying cycle. Clear or restart it once, then investigate if it returns without a known outage. | Check now | Confirm there is no electrical odor, damaged cord, hot plug, or repeatedly tripped breaker. |
| AFAlso Check Vent, Air Flow, AF code | Restricted exhaust airflowWhirlpool uses AF or Check Vent when the dryer detects restricted airflow. The lint screen, connector, exterior hood, or concealed exhaust run may be limiting air movement. | Pause and inspect | Stop the cycle and let the dryer cool. |
| F4 E3Also F4E3, AF, Check Vent | Restricted airflow or blocked ventWhirlpool identifies F4 E3 as restricted airflow. A clogged lint screen or vent, crushed connector, blocked outlet, or overly complex vent run can cause long drying and excess heat. | Pause and inspect | Stop the dryer and let it cool before inspecting airflow. |
| 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. |
| hEAlso HE, HC, HC4, 1 HC, 1HC | Heating or excessive-temperature errorSamsung groups hE with HC and related heating errors. The dryer may be too hot because airflow is restricted; on some electric-dryer conditions, inadequate supply voltage can also be involved. | Pause and inspect | Stop the dryer and let it cool. |
| tEAlso TE, tS, t5, tC, tO, t0, tE3, tC5, tCS, 1 tC, 1tC5, 1tCS | Temperature or thermistor errorSamsung groups tE with several temperature-related dryer codes. A clogged lint screen or vent can trap heat, but a returning code can also require temperature-sensor or circuit diagnosis. | Service recommended | Stop the dryer and allow it to cool. |
