LG Dryer Error Codes — Complete List

LG dryers lean on a mix of letter and number codes, and the ones people hit most — d80, d90 and d95 — come from LG's Flow Sense system watching how freely the exhaust vents: the higher the number, the more restricted the duct. Around those sit a door code (dE), thermistor codes (tE1, tE2 and tE3), a humidity-sensor code (HS), and the power codes PF, nP and PS. Each verified guide below starts with the checks LG itself lists, which for the airflow codes means the lint filter and the full vent run.

• d80 (d75) d80 is LG's Flow Sense system telling you the exhaust duct is about 75–80% restricted: the dryer keeps running but dries slowly, so treat it as an early warning to clean the lint filter and the full vent line before the blockage gets worse.
• d90 (d95) d90 — and the more severe d95 — is LG's Flow Sense system reacting to a badly blocked exhaust of 90% or more by cooling the dryer down and stopping the cycle, so unlike the milder d80 you have to clear the vent before it will run properly again.
• dE dE tells you an LG dryer can't confirm its door is latched shut, so it won't spin the drum — usually because laundry is caught in the seal, the door wasn't pushed firmly enough, or the door switch is worn.
• tE1 (tE3) tE1, and the related tE3, means an LG dryer has detected a problem with its thermistor — the sensor that tracks drum temperature — so a factory reset clears a one-off glitch, but a code that keeps returning points to a failing sensor for a technician.
• tE2 tE2 is LG's temperature-sensor code that shows up in cold conditions — typically when outside air flows back through the exhaust during a steam cycle and cools the duct too fast — so it usually points to the vent and the weather rather than a broken sensor.
• HS HS means an LG dryer has detected a fault with its humidity sensor — the moisture sensor that decides when clothes are dry — and as a fallback the dryer runs a fixed cycle of about two and a half hours, so wiping the sensor contacts clean is the first thing to try.
• PF PF is LG's power-failure code, shown when the electricity to the dryer was cut mid-cycle, and it almost always clears with a simple factory reset rather than any repair.
• nP nP means an LG dryer isn't detecting any current at its heater, which normally points to the home's electrical supply — a half-dead 240-volt circuit, a tripped breaker, or a loose outlet connection — rather than the dryer itself, so the safe checks are the cord and breaker before an electrician.
• PS PS points to improper voltage reaching an LG dryer's control — classically because the white and red wires were crossed on the terminal block when the cord was installed — so it's an installation and wiring issue for a professional rather than a part that has failed.
• CL CL on an LG dryer simply means the Child Lock, also called the control lock, is switched on and disabling the control panel so settings can't be changed; it's a feature rather than a fault, and holding the Child Lock button for about three seconds turns it off.
• 9A5 (gAS) 9A5 — which spells 'gAS' on an LG dryer's display — appears on gas models when the dryer isn't receiving proper gas supply, so the drum turns but the clothes stay cold, and after checking that the gas valve is open the remaining causes are burner parts for a technician.

Don't see your code?

Two things are worth knowing across these codes. The Flow Sense codes d75, d80, d90 and d95 are all the same problem — a restricted vent — at rising severity, so they share one fix: clear the exhaust from the lint screen to the outdoor flap. And the electrical codes are where DIY stops — nP and PS involve the 240-volt supply and terminal-block wiring, while 9A5 (which reads 'gAS' on the display) is a gas-supply fault. For those, do the safe checks outside the machine and hand the rest to a licensed electrician or technician.
