LG dryers
Flow Sense reads your vent. We read Flow Sense.
LG dryers carry the Flow Sense system - d80, d90 and d95 codes that measure how blocked the exhaust duct actually is, in percent. It is a fire-prevention feature as much as a diagnostic, and it makes LG dryers unusually honest about the number-one cause of drying problems: the vent, not the machine.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Electric
DLEX front-loaders
27-inch electric dryers with sensor dry and TurboSteam on upper trims (DLEX4000 class and up).
Gas
DLGX / DLG models
The matching gas machines - igniter, valve coils and flame sensor replace the element.
Ventless
DLHC heat-pump compacts
24-inch ventless heat-pump dryers for closets and condos - condensate path instead of a duct.
Steam
TurboSteam trims
Steam models add a water feed and steam generator to the service map.
Start with the symptom
Common LG dryer problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Drying
Long drying times
The d80 story even without the code: vent restriction is measured before any part.
Heating
No heat, drum turns
Supply leg or element on electric, coils on gas - measured directly.
Symptom
Stops early
Moisture sensing and airflow - tested together.
Drying
Ventless dryer leaving clothes damp
Filters, condenser and condensate path - the DLHC trio.
Symptom
Squeal or rumble
Rollers, idler and belt - the platform wear kit.
Symptom
Steam feature dead
Water feed and steam generator on TurboSteam trims.
Series and model numbers
LG dryer series we service
The suffix letters carry color and steam; the platform letter carries fuel - and on every vented model, Flow Sense watches the duct.
Electric
DLEX models
Model numbers
DLEX4000W, DLEX8900B
What to note
240V machines - one dead supply leg mimics total heat failure.
Gas
DLGX models
Model numbers
DLGX4001W
What to note
GAS display and no-heat patterns start at the supply and coils.
Compact
DLHC ventless
Model numbers
DLHC1455W
What to note
Heat-pump machines - filters and condensate replace the vent story.
Model label
Where to find your LG model number
The model and serial label is inside the door opening, on the front panel below the drum mouth. Open the door and photograph it with any code showing. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
LG dryer alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
d90 or d95 on the display
What it means
Flow Sense measures roughly 90-95% exhaust blockage - the dryer will cool down and stop to prevent a hazard.
Safe check
Stop using the dryer and have the vent cleared - this is the code that prevents lint fires, and it is telling the truth.
Message / alert
d80 appearing occasionally
What it means
Around 80% duct restriction - the machine still runs but dries slowly and hot.
Safe check
Book vent service before it graduates to d90; drying times already tell the story.
LG diagnostics
LG dryer error codes, decoded.
All meanings verified against LG USA's official dryer error-code documentation, including the Flow Sense percentage codes. Vent-side codes are treated as the safety information they are - the duct gets cleared, not argued with.
Error code · d75 / d80 / d90 / d95
Flow Sense duct restriction
What it commonly means
Official: the exhaust duct is clogged to roughly the named percentage - d90/d95 stop the machine for safety.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The full vent run is cleared and airflow verified with the dryer's own sensing; the machine side is checked for lint intrusion.
Error code · tE1 / tE2 / tE3 / tE4
Thermistor faults
What it commonly means
Official: the temperature sensing circuit has failed or read out of range - tE2 is documented around cold starts and steam cycles.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Thermistor resistance measured, sensor or harness replaced, and the heat circuit verified end to end.
Error code · dE
Door not closed
What it commonly means
Official: the door is not detected closed.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Latch and switch tested; the honest first check is simply firm reclosing.
Error code · nP
No power to heater
What it commonly means
Official: no current detected at the heater - wiring or supply-side fault.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The 240V supply is measured at the terminal block, then heater circuit and connections.
Error code · PS
Supply voltage / reversed wires
What it commonly means
Official: improper voltage, possibly reversed wire connections at the terminal.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The connection is corrected to spec - an installation-side electrical fix.
Not a fault · CL
Child lock
What it commonly means
Officially a feature, not a fault - the control is locked.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Released per the model's key sequence; documented, not repaired.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
LG products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.
Next step
The $99 diagnostic visit confirms the actual fault before any repair is authorized. Book a visit or call (619) 877-6701.
Preventive service and owner care
LG dryer maintenance
Alpha Pro provides preventive and general maintenance for LG dryers. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Lint screen: clean before every load; wash off softener film monthly.
Vent duct: keep the exterior vent flap free and the duct path short and unkinked; book duct cleaning when drying slows.
Heat-pump filters: on heat-pump models, clean the secondary filters per the manual.
Loading: avoid overloading - it extends cycles and stresses bearings and belts.
Professional maintenance
Inspection follows the appliance design
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.
Airflow and vent restriction
Heating performance - element, igniter, or heat pump
Moisture sensing and cycle control
Drum rollers, belt, and bearings

Diagnosis before parts
A straightforward three-step service process
1
Describe the symptom
Call or book with the model label, exact behavior, any displayed codes, photos, and access notes.
2
Evaluate the system
The technician examines the reported condition in context: airflow, heat, cycle behavior, drum condition, controls, and relevant components.
3
Review the recommendation
Findings and proposed work are explained before repair proceeds. The residential diagnostic is credited toward an approved repair.

Helpful answers
LG dryer service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day LG dryer repair in San Diego?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a LG dryer?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
Is d90 telling me my dryer is broken?
No - it is telling you your vent is about 90% blocked, and stopping for safety. Vent clearing resolves it; ignoring it is how lint fires start.
Why does my electric LG dryer run but not heat?
Often one dead leg of the 240V supply, then the heater circuit - nP on the display points the same direction. Both are measured, not guessed.
What does tE1 mean?
A thermistor fault - the temperature sensor circuit. Official first step is a reset; a returning tE1 is a sensor-circuit repair.
Where is the model number?
Inside the door opening on the front panel - open the door and photograph the label.
Do you service the 24-inch ventless LG dryers?
Yes - DLHC heat-pump compacts, where filters and the condensate path replace the vent as the first diagnosis.
