LG Refrigerator & Freezer — Error Codes
| Code | What it means | Urgency |
|---|---|---|
| Er dH |
Defrost Heater Malfunction
Defrost heater or safety fuse failed to melt frost off cooling coils within 1 hour. Causes thick frost buildup and loss of cooling.
|
High |
| Er FF |
Freezer Evaporator Fan Motor Error
Freezer evaporator fan motor is defective or locked by ice. Cold air stops circulating to the refrigerator compartment.
|
High |
| Er CF |
Condenser Fan Motor Malfunction
Condenser fan at the bottom rear near the linear compressor isn't running, risking severe compressor overheating.
|
High |
| Er IF / 1F |
Ice Maker Fan Error
In-door ice compartment fan is frozen over or damaged. Ice production stops and frost builds inside the ice duct.
|
Medium |
| Er FS / Er rS |
Freezer / Refrigerator Sensor Fault
FS indicates a freezer thermistor failure; rS indicates a refrigerator fresh food thermistor short or open circuit.
|
Medium |
| OFF / OFF OFF |
Demo / Display Mode
Showroom mode activated. Lights work but compressor and fans are shut off. Not a hardware failure.
|
Low |
LG French Door refrigerators with Linear Compressors rely heavily on proper ventilation. If you see "Er CF", turn off the unit until the condenser fan is inspected. Running an LG linear compressor with a dead fan can quickly cause irreversible compressor failure.
Signs your LG refrigerator needs a professional
- Freezer stays cold while the fresh food section warms up above 45°F
- A loud humming or clicking sound from the bottom rear every few minutes
- Ice maker stopped dispensing and frost is visible inside the ice chute door
- Water dripping into crisper drawers or pooling underneath the front legs
LG Washing Machine — Error Codes
| Code | What it means | Urgency |
|---|---|---|
| OE |
Drain Fault
Water did not drain out within the allowed time. Usually caused by a clogged coin trap/drain pump filter or broken pump.
|
High |
| LE |
Motor Locked Error
Direct Drive motor is unable to rotate the drum. Common causes include overloaded tub or a defective Direct Drive Hall Sensor.
|
High |
| UE / uE |
Unbalanced Load Error
uE means washer is attempting auto-rebalance; UE means cycle stopped due to severe imbalance or worn tub suspension rods/shocks.
|
Medium |
| IE |
Water Inlet Error
Washer failed to fill with water. Check household water supply valves and mesh inlet filter screens on back of valve.
|
Medium |
| PE |
Water Level Pressure Sensor Fault
Pressure sensor switch or air tube is disconnected, clogged, or electrically defective.
|
High |
| dE / dE1 / dE2 |
Door Latch Switch Fault
Washer door/lid is open or door lock switch assembly failed to lock properly prior to spin cycle.
|
Medium |
If your LG front-load washer displays "LE", don't immediately buy a new motor. In 90% of cases, LG Inverter Direct Drive motors are fine; it's almost always a $30 Hall sensor (rotor position sensor) that failed on the back of the stator.
Signs your LG washing machine needs a professional
- Loud banging or roaring jet-engine sound during high-speed spin (failed tub bearing)
- Water remaining inside drum after cycle finishes despite cleaning front drain filter
- Door locked shut at cycle end with water trapped inside
- Leaking water from under the front rubber door boot gasket during wash cycle
LG Dryer — Error Codes
| Code | What it means | Urgency |
|---|---|---|
| d80 / d90 / d95 |
Exhaust Duct FlowSense™ Restriction
FlowSense system detected 80%, 90%, or 95% blockage in house exhaust ducting. Fire hazard if not cleaned.
|
High |
| tE1 / tE2 / tE3 |
Thermistor Temperature Sensor Error
Exhaust thermistor sensor is shorted or open, preventing main control board from regulating heating element or gas burner.
|
Medium |
| PS |
Power Supply Voltage Error
Incorrect voltage input detected at terminal block connection (electric dryers require dual 240V lines).
|
High |
| nPo |
Gas Supply / Ignition Fault
Gas dryer failed to detect flame ignition or gas supply valve is shut off.
|
Medium |
| HS |
Humidity Sensor Error
Sensor bars inside drum under filter housing are disconnected, dirty with fabric softener residue, or shorted.
|
Low |
If your LG dryer displays "d80" or "d90", the issue is almost always in your wall or roof exhaust vent line, not inside the dryer itself. Clean the entire vent duct run before replacing dryer thermal fuses or thermostats.
Signs your LG dryer needs a professional
- Clothes taking 2 to 3 full cycles to dry completely
- Screeching, thumping, or grinding noises while the drum turns
- Dryer running and tumbling but producing zero heat (blown element or thermal fuse)
- Control panel turns on but start button clicks without motor turning
LG Dishwasher — Error Codes
| Code | What it means | Urgency |
|---|---|---|
| AE / E1 |
Water Leak Detected
Float switch in bottom tray detected water leak. Drain pump automatically operates continuously to prevent flooding.
|
High |
| OE |
Drain Fault
Water failed to pump out of the tub within 5 minutes. Clogged sump filter, blocked garbage disposal knockout, or pump failure.
|
High |
| LE |
Direct Drive Circulation Motor Error
Circulation pump motor circuit fault or impeller jammed by foreign object. Wash arms will not rotate.
|
High |
| IE |
Water Inlet Fill Error
Dishwasher did not fill to minimum water level threshold. Check supply valve under sink and inlet valve screen.
|
Medium |
| HE |
Heater Circuit Failure
Heating element or control board heater relay failed. Water will not heat properly and drying cycle fails.
|
Medium |
| tE |
Thermistor Temperature Sensor Error
Temperature sensor circuit is open or shorted, preventing proper wash water thermal regulation.
|
Medium |
An "AE" or "E1" code means water has reached the emergency drip pan under the dishwasher tub. Unplug the machine immediately. Continuous running of the drain pump without addressing the leak source will burn out the drain motor.
Signs your LG dishwasher needs a professional
- Standing dirty water covering bottom mesh filter after cycle finish
- White suds leaking from bottom door seal onto floor
- Dishes coming out cold and wet with soap tablet un-dissolved
- Loud buzzing sound when wash cycle initiates without spray arm activity
LG Oven & Range — Error Codes
| Code | What it means | Urgency |
|---|---|---|
| F9 / F19 |
Oven Heating Failure
Oven cavity failed to reach set temperature within programmed time limit. Igniter, bake element, or relay board fault.
|
High |
| F3 |
Oven Temperature Sensor (RTD) Shorted
Temperature probe sensor circuit resistance is shorted. Oven disables heating elements for safety.
|
Medium |
| F1 |
Control Board Keypad Short
Touch membrane keypad buttons jammed or control board microcontroller internal error.
|
High |
| F7 |
Door Lock System Failure
Motorized door lock assembly failed to engage or disengage switch during self-clean cycle.
|
Medium |
LG gas ranges with ProBake Convection® feature the bake burner at the rear wall rather than under the oven floor. If the oven takes over 15 minutes to preheat, your gas igniter is likely weak and drawing insufficient amperage to open the safety valve.
Signs your LG oven or range needs a professional
- Gas surface burners clicking continuously after igniting
- Oven door stuck locked shut after running self-clean cycle
- Bake element glowing unevenly or sparking inside cavity
- Error code F9 appearing during preheat cycle
LG Repair FAQ
How do I reset an LG appliance error code?
You can perform a hard reset by switching off the dedicated circuit breaker at your home electrical panel (or unplugging the unit) for 10 full minutes. Restore power to see if the code clears. If hardware is damaged, the code will return when activated.
What does "CL" mean on my LG appliance?
CL is not an error code—it stands for Child Lock. Press and hold the Control Lock or Child Lock button on the control panel for 3 to 5 seconds to unlock your control panel.
Why is my LG washer showing LE code?
LE stands for Locked Motor Error. It usually occurs when the tub is severely overloaded or when the Direct Drive Hall sensor (rotor position sensor) fails. Try clearing heavy items and restarting.
Do you use genuine LG replacement parts?
Yes, all LG repairs are completed using OEM factory replacement parts to maintain optimum efficiency, reliability, and appliance performance.
