LG Dryer Error Codes
LG dryers report airflow, moisture sensor, and gas/electric heat faults as alphanumeric codes. Flow Sense models track exhaust restriction over multiple cycles before showing d80–d95.
General troubleshooting
Try these checks before opening a specific error code page—they resolve many LG dryer faults without parts.
- 1Clean the lint filter and vacuum the lint trap housing before every load
- 2Inspect the full vent run to the exterior hood—remove lint at elbows and confirm the damper opens
- 3Wipe the moisture sensor bars inside the drum with rubbing alcohol if cycles finish early
- 4On gas dryers, confirm the supply valve is open and the vent is not crushed behind the unit
- 5Run a Timed Dry on high heat with a small wet load to separate airflow issues from sensor faults
Common symptoms
Owners often search for a code after noticing one of these issues on their LG dryer:
- Clothes still damp after a full Normal cycle (flow restriction or weak heat)
- d80, d90, or d95 after several loads when the vent run is long
- TE or tE1 temperature errors on electric and heat-pump models
- Dryer runs but produces no heat on gas units (ignition-related codes)
- Drum turns but display shows door or moisture sensor faults
All LG dryer error codes
| Code | What it means | Guide |
|---|---|---|
| AE | Auto shutoff from internal faultAE is an Auto Error shutoff—the control board stopped operation to protect components, often following overheating, repeated sensor faults, or an internal self-test failure. | View fix → |
| CE | Communication fault between control boardsCE is a Communication Error between the main control and display or inverter sub-board. Buttons may freeze and the drum may not start even though power is present. | View fix → |
| CL | Child lock is active—not a faultCL displays Child Lock engaged. The control panel buttons are disabled to prevent accidental cycle changes—this is intentional, not a malfunction. | View fix → |
| D80 | Flow Sense detected roughly 80% vent restriction blocking exhaust airflowLG D80 is a vent-restriction warning on dryers equipped with Flow Sense monitoring. The control compares exhaust temperature rise and airflow characteristics against expected profiles; when back-pressure indicates roughly 80% blockage, D80 displays before the dryer enters a hard shutdown. On electric models such as DLE7300WE and DLEX4000W, D80 almost always means lint-limited airflow through the duct path—not a heating element failure. Note: on some LG gas dryers, a displayed d80 can relate to gas supply issues; on electric Flow Sense units, treat D80 as a vent hygiene fault first. Uncorrected restriction progresses to D90 and D95 with longer dry times and higher element stress. | View fix → |
| D90 | Severe vent blockage near 90%D90 means Flow Sense measured about 90% blockage in the exhaust path. At this level the heating element may cycle off early to prevent overheating, leaving clothes damp after extended runs. | View fix → |
| D95 | Critical vent blockage about 95%D95 is the most severe Flow Sense code—about 95% exhaust restriction. LG treats this as an immediate safety alert. The dryer may refuse heat or shut down mid-cycle until airflow is restored. | View fix → |
| DE | Door switch not confirming closeddE means the door switch never confirmed closure before the motor or heat circuit energized. LG dryers will not tumble with an open-door signal. | View fix → |
| E13 | Steam generator or steam function faultE13 appears on LG steam-capable dryers when the steam generator cannot produce steam—water not reaching the steam chamber, a clogged nozzle, or a steam valve fault. | View fix → |
| FE | Power frequency out of rangeFE reports a frequency or power-quality issue detected by the inverter or control board—more common on LG heat-pump and inverter-motor dryers where stable AC input is required for compressor and drum drive. | View fix → |
| HE | Heater circuit not producing heatHE indicates a heating error—the dryer ran but exhaust temperature never reached the target within the allowed time. On electric models this points to the element or thermal fuse; on gas models, igniter or gas supply. | View fix → |
| HS | Humidity sensor reading failedHS is a Humidity Sensor error on sensor-dry models. The board cannot read fabric moisture level, so automatic cycles may stop early or never advance from sensing mode. | View fix → |
| NF | No gas flame detected on gas modelsnF is No Flame on LG gas dryers. The igniter glowed or the gas valve opened but the flame sensor never detected combustion within the timeout—so heat stops for safety. | View fix → |
| PF | Power lost during cyclePF is Power Failure—the board lost AC during operation. It is informational, not a parts fault. Some LG models let you resume; others require restarting the cycle. | View fix → |
| TE | Thermistor fault—alternate displaySome LG dryer panels show tE with mixed case for the same thermistor fault as TE. Exhaust temperature feedback failed—often after vent blockage overheated the blower area. | View fix → |
| TE1 | Inlet thermistor reading out of rangetE1 is a thermistor sub-fault on LG condenser and heat-pump dryers—the sensor at the inlet heat exchanger sent resistance outside the board's valid range. Unlike exhaust tE, tE1 points to the cooler inlet path where lint and condensate collect. | View fix → |
