LG dryers show a short code when something’s wrong — and most of the common ones come down to airflow you can clear yourself. Here’s what each LG dryer error code means, what to try first, and when to call a technician.

LG dryer error codes at a glance

Codes vary by model — check your manual if yours isn’t listed.

The most common codes — and how to fix them

d80 / d90 / d95 — blocked exhaust

The dryer detects the vent is 80–95% clogged and shuts off to avoid overheating. Try first: clean the lint filter, disconnect and clear the exhaust hose, and check the outside vent flap. This is the most common LG dryer code by far.

tE1 / tE2 — temperature sensor

A thermistor (temperature sensor) fault. This one usually isn’t a DIY fix — it needs a technician to test and replace the sensor.

dE — door

The dryer can’t confirm the door is closed. Try first: close it firmly and check the door switch/latch.

PS — power

Improper voltage at the cord — often the wires reversed on the terminal block after a move. Best checked by a technician.

One safety note: a clogged lint screen or vent is the #1 cause of dryer error codes — and a real fire risk. Clearing it often fixes the code outright; see our maintenance guide for how.

The bottom line

Most dryer codes come down to a clogged vent or an inexpensive part (a thermal fuse, thermistor, or heating element) — repairing is almost always cheaper than replacing. If a code won’t clear, we repair LG dryers (and every major brand) across DFW, usually same-day. Not sure yours is worth fixing? See our dryer repair-or-replace guide.
