What an LG dryer code can and cannot tell you
LG dryers show codes in the time display, most as two or three characters: tE1, nP, dE, PS. The vent family works differently. A d80, d90 or d95 is LG’s estimate of how restricted the exhaust has become, at roughly 80, 90 and 95 percent. Those are warnings about the house as much as the dryer, and people tend to ignore them until the drying time doubles. Other codes point at the machine: a thermistor reading out of range, no current reaching the heater, a door that will not confirm closed. In every case the code names the check that failed, not the part. A tE1 can be a sensor, a connector or a board. Our technicians confirm with a meter before anything is replaced.
Vent codes lead our LG dryer calls in Olympia, Lacey and Tumwater, and the weather explains why. With humidity near 80 percent and fog through fall and winter, warm exhaust cools inside long duct runs through crawlspaces and garages, condenses, and glues lint to the duct walls. Moss and needles then choke the outside hood. tE2 follows the cold: LG links it to low temperatures, and frost can hold a vent flap shut on one of the area’s freezing nights. nP and PF follow PSE outages after windstorms. Gas LG dryers, common in homes on PSE gas, add the gAS code, and propane homes on the rural edges see it too.
LG dryer codes and the first safe step for each
| Code | What it means | Safe first check | When to call us |
|---|---|---|---|
| LG · d80 | Exhaust duct is about 80 percent clogged. | Clean the lint filter; with the dryer running, hold a hand by the outside hood. | Airflow stays weak after the screen and hood are clean. |
| LG · d90 / d95 | Exhaust duct is about 90 to 95 percent blocked. | Stop drying; clear lint, moss and needles from the outside hood. | Hood is clear and the code remains, so the hidden duct is blocked. |
| LG · tE1 | The dryer detected a thermistor problem. | Unplug, hold START/PAUSE five seconds, restore power, and retry. | tE1 returns after the reset; we test the thermistor circuit. |
| LG · tE2 | Thermistor problem, normally in cold conditions or during steam cycles. | Check the outside vent for frost; run an empty cycle to warm up. | tE2 persists on mild days with a clear vent. |
| LG · tE3 | Another thermistor fault flagged by the control. | Use the same unplug and START/PAUSE reset, then retry. | Any repeat; we measure the sensor before replacing anything. |
| LG · nP | No current detected at the heater; a wiring or supply problem. | Reset the dryer’s breaker, leaving it off at least ten seconds. | Still no heat after the breaker reset; we test the heater circuit. |
| LG · PS | Improper voltage at the cord, possibly red and white wires reversed. | Reset the breaker; leave the cord terminal block to a professional. | PS stays after a reset, especially after a cord change. |
| LG · dE | Door is not completely closed. | Push the lint filter fully in; clear clothing from the door edge. | Door looks aligned and dE still shows. |
| LG · F0 / FO | Lint filter is out or not inserted properly. | Remove the lint filter and seat it firmly in its housing. | Filter is seated and the code stays on the display. |
| LG · HS | Humidity sensor error; a cycle may run about two and a half hours. | Wipe the sensor bars below the lint filter with a damp cloth. | Clean bars still misread, and loads overdry or stay damp. |
| LG · PF | Power failed during a cycle, usually from an outage. | Unplug, hold START/PAUSE five seconds, restore power, restart. | PF appears without an outage, or with other codes. |
| LG · gAS | Gas dryer is not getting a proper gas supply. | Leave fittings alone; note whether other gas appliances light normally. | Always. A gas odor means everyone steps outside before phoning the supplier. |
| LG · E13 | Hybrid condensing models: drain hose kinked, clogged, or sump water frozen. | Straighten the drain hose, warm the room, then press START/PAUSE. | Hose is clear and the room is warm, yet E13 returns. |
Resetting an LG dryer, and the codes you should not reset
LG’s reset for most dryer codes: unplug the dryer or switch off its breaker, press and hold START/PAUSE for five seconds while it is off, then restore power and start a cycle. For nP, LG says to leave the breaker off at least ten seconds. That sequence suits tE1, tE3 and PF after a single glitch. It does not suit d90 or d95. LG’s guidance is to stop using the dryer until the exhaust is cleaned, since a nearly blocked duct traps heat and lint together. If the code comes straight back after a reset, or anything smells scorched, leave the dryer unplugged and let us test it.
An LG dryer visit, start to finish
An LG dryer visit starts with the code and your vent. Our technician reads the display, checks airflow at the outside hood, then meters the part the code points to: thermistor, heater element, high-limit, door switch, gas valve coils. We tell you which part quit and why, then hand over the repair figure on paper before a screw turns. Approving it pulls the $99 into that figure; passing on it keeps your bill at the $99. We carry common LG dryer parts, run a full heat cycle afterward, and leave a written warranty. Homes from Cooper Point to the Lakes get the same routine.
LG dryer code questions
Is an LG dryer safe to run with a d90 code?
LG says no. A d90 or d95 means the exhaust is roughly nine-tenths blocked or worse, and the dryer should not run until the duct is cleaned. Clean the lint filter, then check the outside hood for lint, moss or needles, which collect easily around Olympia. If the hood is clear and the code remains, the blockage sits inside the duct run, sometimes in a crawlspace section.
Why does my LG dryer show tE2 on cold mornings in Tumwater?
LG ties tE2 to thermistor readings in cold conditions. On one of the area’s freezing nights, a dryer in an unheated garage can start far below its expected range, and frost can hold the outside vent flap shut. Check the hood, then run an empty cycle to warm the drum, as LG suggests. If tE2 shows on mild afternoons too, we test the thermistor and its wiring.
What does nP mean on an LG electric dryer?
nP means the control sees no current at the heater. An electric LG dryer runs on a 240-volt circuit with two breaker poles, and one tripped side can leave the drum turning with no heat. Reset the breaker, leaving it off at least ten seconds. If nP stays, our technician measures the supply and the heater circuit, including the element and its safety devices.
Why does my LG dryer take two cycles in a damp Lacey laundry room?
Humid air and a long vent work against each other. Lacey’s wet months bring fog and humidity near 80 percent, so the exhaust cools and condenses before it reaches the outside, and wet lint builds up in low spots. Watch for d80 on the display, even if the dryer keeps going. Our technicians start outside with an airflow reading at the hood, and only then move to the heater, thermistors and moisture sensor bars.
Should a homeowner touch the gas valve when an LG dryer shows gAS?
No. LG mentions checking the supply valve, but we keep homeowners away from gas fittings. Note whether your range or furnace lights normally and tell us. Any gas odor means stepping outdoors first; phone PSE or your propane supplier from the yard. Once the supply checks out, our technician puts a meter on the igniter, then the flame sensor and each valve coil, to learn why the burner stays dark.
