Michael Thompson Key Takeaways
- Read the LG dryer code exactly as shown, including lowercase letters, because tE1, dE and nP are different from their capital forms.
- Duct codes d90 and d95, sensor codes tE1 to tE3, GAS and E13 mean stop using the dryer.
- HS, nP, PF, F0 and dE are lower-risk codes with simple first checks: sensor bars, the double breaker, the filter and the door.
- Write down the code, check the lint filter and duct, reset once and never bypass a sensor or a switch.
- A code that returns after a reset, or any stop code, needs a technician.
The Bottom Line
Sort the code into stop, work around with care or simple check, act on that first and use the code page for the detail. If the code returns after a reset, the price of the repair is confirmed after diagnosis, with a written estimate before work begins.
An LG dryer reports most of its problems as a short code on the display, and the code decides what to do next: stop and unplug, clean something, or carry on with care. This LG dryer error code list groups the codes covered on this site by that first reaction, so you can act before you read the whole page. Each code links to its own page in our LG dryer error codes section, which has the symptoms, the safe checks and the point at which to call a technician.
| Code | What the site says it means | First reaction |
|---|---|---|
| d80 | Duct blockage, 80% | Clean the duct before regular use |
| d90 | Duct blockage, 90% | Stop; clear the duct |
| d95 | Duct blockage, 95% | Stop and unplug; professional duct cleaning |
| tE1, tE2, tE3 | Inlet, secondary and exhaust temperature sensor errors | Stop; a technician tests the sensor |
| GAS | No gas supply to the dryer | Stop; check the valve, never a gas smell |
| E13 | Water leak in the base pan | Stop and unplug |
| HS | Humidity sensor fault | Clean the sensor bars; use timed dry |
| nP | No power to the heater | Check the double breaker first |
| dE | Door open or door switch fault | Close the door; check the latch |
| F0 | Lint filter missing or unseated | Seat the filter |
| PF | Power failure during the cycle | Clear it and restart |
How Do You Read an LG Dryer Error Code?
Off the display, exactly as it appears, including the difference between capital and lowercase letters. LG dryer codes such as tE1, dE and nP are written with a lowercase first letter, and a code read wrongly sends you to the wrong page. If the display is blank, there is no code to read and the problem is probably power, which the LG dryer not heating guide and the breaker check in the nP section below cover.
This list does not describe a diagnostic mode that retrieves stored codes, because the pages of this site do not describe one, and the steps differ between models. If your manual describes one, follow the manual.
Which LG Dryer Codes Mean Stop?
The ones that involve fire, gas, water or temperature control. For those, the pages say not to keep using the dryer, and they explain why in plain terms.
- d90 and d95. The exhaust duct is critically blocked. The d95 page calls it a fire-risk condition and says to unplug the dryer until the duct is professionally cleared.
- tE1, tE2 and tE3. A temperature sensor fault. The dryer cannot regulate heat without it, and the pages say not to bypass the sensor.
- GAS. No gas supply detected. The page says any gas smell means evacuate and call the gas utility.
- E13. Water in the base. The page says to unplug the dryer because of the shock hazard.
The duct codes also have their own guides: LG dryer d80 code covers the first level of blockage, and LG dryer GAS error code covers the gas dryer fault.
Which Codes Can You Work Around for Now?
A few, with limits. The pages describe these as lower-risk faults that you can often deal with yourself, but none of them is a reason to ignore the code.
- d80. The dryer can be used briefly, but the page warns against prolonged use with an 80 percent blocked duct.
- HS. Auto-dry cycles will not work correctly, but timed dry cycles can be used while you clean the sensor bars.
- nP. The drum tumbles with no heat. Check the double-pole breaker, which can be half tripped without looking it.
- PF. An informational code after a power interruption; clear it and restart. If it appears every cycle with no outage, suspect the breaker.
- F0 and dE. The dryer will not start until the filter is seated and the door switch reads closed.
What Should You Do Whichever Code Appears?
Write the code down, note what the dryer was doing and then follow the same short routine. It rules out the common causes and gives a technician the information needed to find the rest.
- Check the lint filter and the duct first. Airflow problems cause more LG dryer codes than any part failure.
- Reset once. Unplug the dryer for five minutes, as the tE1 and dE pages suggest, and try a short cycle.
- Do not bypass a sensor or a switch. They are safety devices.
- Stop at a burning smell or a hot cabinet. Unplug the dryer.
If the dryer needs cleaning, our guide to LG dryer maintenance and the guide on how to clean an LG dryer give the routine.
Why Airflow Sits Behind So Many Codes
A dryer is a heater and a fan, and almost everything it reports is about whether the heat is going where it should. A blocked duct raises the temperature inside the cabinet. The d80, d90 and d95 codes are the dryer's own warning about this, and the pages describe them as a flow-sensing alert that clears by itself once the airflow is restored. A temperature sensor that trips, a thermal fuse that blows and a cycle that ends with damp clothes can all follow from the same restricted vent, so a code that looks electrical is sometimes a vent problem in disguise.
That is why the first checks for nearly every code are the lint filter and the duct, and why a technician will often start there. It is cheaper to find a blocked vent than to replace a sensor that was only reporting what it saw.
- Clean the lint filter every load. A film from dryer sheets can block it even when it looks clean.
- Look at the vent hood outside. The flap should open freely while the dryer runs.
- Check the duct for kinks and crushed sections. Especially behind the dryer, where it is pushed against the wall.
- Time a cycle. A cycle that takes far longer than it used to is an early warning, before any code appears.
Codes You Should Not Chase One at a Time
When two or three codes appear in the same week, treat them as one problem until proved otherwise. A duct warning followed by a sensor code is more likely a vent that has been cooking the sensor than two independent failures, and a power failure code followed by a no-heat code can be a half-tripped breaker. Write the codes in the order they appeared and with the dates, and give the whole list to the technician.
Likewise, do not clear a code over and over to keep drying clothes. A code that is cleared and returns is a measurement, not a nuisance, and each repeat is the dryer telling you the same thing.
When to Call a Technician
When a code returns after a reset, when it is one of the stop codes, or when the cause is a sensor, a gas component or a leak. A diagnostic visit for an LG appliance starts from $89, with the final price confirmed after diagnosis and a written estimate before any work begins. Schedule a visit or read about LG dryer repair.
