LG dryers display specific error codes when a component fails or a safety condition is detected. Reading LG dryer error codes correctly saves a service call in some cases and confirms when dryer repair is unavoidable in others. This guide covers the codes homeowners in Toronto see most often and what to do about each one.
LG dryers use a combination of letters and numbers to point to a specific fault rather than a generic “something’s wrong” light. Digital display models show the code directly on the control panel. Older LED-only models communicate through blink patterns, counted and matched against a chart in the owner’s manual. A quick reference sticker is often found inside the lint filter housing or behind the access panel.
These codes report the percentage of exhaust duct blockage, from 75% to 95%. The hot, humid air from the dryer has to go somewhere, or the moisture will stay in the drum and clothes. On gas dryers, D80 can also point to a lack of gas supply to the unit. Clean the lint tray after every load, check for a crushed or kinked exhaust hose, and reduce load size to help airflow. If the code returns after cleaning, the blockage is likely further down the duct run and needs a professional vent cleaning. This is one of the more urgent LG dryer error codes, since a blocked exhaust is a recognized fire risk in Toronto homes with long duct runs.
A door error. Open the door, check that the lint filter is fully seated, and remove any clothing caught in the door seal. On a new unit, inspect for a bent door frame. If the code repeats after a reset, the unit needs dryer repair.
A thermistor (temperature sensor) fault. tE1 is an open circuit, tE2 usually appears during steam cycles in cold conditions, and tE3 points to the outlet thermistor specifically. Try the reset: unplug the dryer or trip the breaker, then press and hold Start/Pause for 5 seconds before restoring power. If the code returns, the thermistor needs to be tested with a multimeter and likely replaced, which is a job for LG dryer repair rather than a DIY fix.
A power failure code. This typically clears itself once power is restored and rarely needs further action.
No power detected at the heater. Check that the power cord is plugged into a grounded 240V outlet matching the dryer’s rating plate, then reset the breaker for at least 10 seconds. If the dryer is still not heating at this stage, the unit requires a repair service.
A humidity sensor fault. Clean the sensor bars inside the drum, below the lint filter, with a damp cloth or rubbing alcohol and let them dry fully before the next cycle.
The lint filter isn’t seated correctly. Remove it and reinsert it fully into the housing.
Appears only on hybrid condensing models and points to a kinked, crushed, or frozen drain hose. Check the hose isn’t extended beyond the standard LG length, since extensions increase resistance and can trigger the code repeatedly.
Child Lock is active; it is not a fault. Hold the lock button for 3 seconds to clear it.
A communication error between the main control board and the display board.
Resets and cleaning resolve some LG dryer error codes, mainly filter, door, and power-related ones. Codes that repeat after a reset, especially the D-series duct codes, thermistor faults, and nP, indicate a component failure or a wiring issue that needs a technician. Running the dryer with a D90 code showing is not advisable given the fire risk from a near-fully blocked exhaust.
Dryer Repair diagnoses and repairs LG dryer error codes for households across the GTA. Services include thermistor replacement, control board repair, door latch adjustment, and exhaust duct inspection. Technicians work on electric, gas, and ventless LG dryer models and carry parts for D-series, tE-series, and nP faults. The service area covers Toronto, Etobicoke, Scarborough, North York, East York, Vaughan, and Woodbridge.
