Quick answer
On LG dryers, d80, d90 and d95 are Flow Sense warnings that the exhaust vent is about 80%, 90% or 95% restricted; clean the lint filter, the duct and the outside vent. tE1 and tE2 point to a temperature sensor (thermistor) circuit. PS on an electric dryer usually means it is not getting full 240-volt power, and nP that the heater is not getting power. dE means the door is open or its switch has failed, and HS a humidity sensor fault. Codes vary by model, so check your manual. Call (888) 217-0236 to reach an appliance repair company taking calls in your ZIP; the line is answered 24/7.
Follow the short menu, then your 5-digit ZIP. The line goes quiet for a few seconds while it connects; stay on. If it does not connect, call once more: companies taking calls change minute to minute.

LG dryers show a short code on the display when they detect a problem. Some are warnings you can clear yourself in a few minutes; others point to a part. Codes and meanings vary by model, so your owner's manual, or LG's support site with the model number from the label inside the door, is the final word.
Vent Codes (Flow Sense)
| Code | Usual meaning | What to do |
|---|---|---|
| d80 | Exhaust about 80% restricted | Clean the lint filter, duct and outside vent |
| d90 | About 90% restricted | Same, and check the duct for crushing or long runs |
| d95 | About 95% restricted | Stop using it until the vent is cleared |
| Flow Sense light | Restriction detected | Same as above |
These are the most common LG dryer codes and the ones that matter for safety. The U.S. Fire Administration names failure to clean as the leading cause of home dryer fires. See dryer not drying clothes.
Power and Heat Codes
| Code | Usual meaning | What to do |
|---|---|---|
| PS | Electric dryer not getting full 240-volt supply | Reset both halves of the double breaker; if it returns, the outlet, cord or wiring needs checking |
| nP | Heater not getting power | Breaker first; then a technician |
| tE1 / tE2 | Temperature sensor (thermistor) circuit fault | Technician repair; the sensor or its wiring |
| HS | Humidity (moisture) sensor fault | Clean the sensor bars inside the drum; if it returns, a repair |

Door and Other Codes
| Code | Usual meaning | What to do |
|---|---|---|
| dE, dE1, dE4 | Door open or door switch fault | Close firmly, check the latch; a failed switch is a repair |
| CL | Child lock on | Hold the child lock button to release |
When the Code Points to a Repair
- PS or nP returns after the breaker is reset.
- tE codes, which are sensor or wiring faults.
- dE with the door firmly shut.
- A d-code that comes back right after the vent is cleaned, which can mean a blocked blower or a failing sensor.
If the dryer is not heating at all, see dryer not heating. Angi puts typical dryer repairs at $100–$430. See dryer repair.

Frequently Asked Questions
What does d80 mean on an LG dryer?
It is a Flow Sense warning that the exhaust vent is about 80% restricted. d90 and d95 mean about 90% and 95%. Clean the lint filter, the duct and the outside vent hood.
What does PS mean on an LG dryer?
On an electric dryer it usually means the dryer is not getting its full 240-volt supply, often half of the double breaker or a wiring issue at the cord.
What does tE1 mean on an LG dryer?
A fault in a temperature sensor circuit: an open or shorted thermistor or its wiring. That is a technician repair.
Will the d80 code stop my LG dryer?
It is a warning and the dryer may keep running, but a restricted vent lengthens drying, overheats parts and raises fire risk.
