LG Dryer Error Codes D80, D90, D95, tE1, tE2 — What They Mean & How We Fix Them

LG electric and gas dryers (DLE / DLG / DLEX / DLGX series) measure exhaust airflow on every cycle and throw D80 / D90 / D95 long before the thermal fuse blows — that's a gift if you clean the vent before the heater fails. The other common LG dryer faults are tE1 / tE2 (thermistor) and dE (door switch).

What we fix in Minneapolis

The Minneapolis repair mix

LG Smart Diagnosis for dryers

LG dryers built 2011+ support Smart Diagnosis: press and hold the Power button, then within 3 seconds press and hold the temperature button while holding your phone speaker against the Smart Diagnosis icon (or use the LG ThinQ app over Wi-Fi on newer models). The dryer transmits stored fault history as a series of tones. The app decodes it to a code list. Useful when an intermittent fault won't display long enough to read.

D80 / D90 / D95 — vent restriction codes

LG measures outlet temperature rise and time-to-dry, then estimates vent restriction. D80 means the dryer thinks the vent is 80% restricted, D90 = 90%, D95 = 95%. The dryer still runs but cycle times double or triple and the heater works overtime. Clean the full vent run from dryer outlet to exterior cap — flexible transition first, rigid run second, exterior cap last (cap clogs from dryer lint + bird nests are common in Twin Cities homes). $185 add-on for full vent cleaning. Ignore D95 and the next failure is the heating element ($385–$525) plus thermal fuse.

tE1 / tE2 — thermistor faults

tE1 is the outlet thermistor (open or shorted); tE2 is the inlet thermistor. Cheap part, easy swap — $225–$285 all-in. Heat soak from a restricted vent shortens thermistor life, so on a tE1 / tE2 we also inspect the vent path.

Field-service notes on dryer repair

On dryer repair, we keep the diagnostic tight because the failure catalog on this brand is well-documented. The Twin Cities humidity swing — dry January to sticky July — cycles refrigerator door gaskets hard; a gasket that seals in March can pull ambient air by August and drive up compressor run time 15–20%.

Because this page focuses on lg smart diagnosis for dryers, our tech opens the call by isolating that subsystem before touching anything else. Wear parts (belts, pumps, igniters, valves) ship from our truck stock; boards and sealed-system parts are OEM-only from Marcone or the manufacturer's direct distributor. The $149 residential diagnostic is credited toward the repair if you approve; if you don't, you pay only the diagnostic and we leave a written scope. Every completed repair carries a 1-year parts and labor warranty in writing. The section above covers the specific failure surface — lg dryers built 2011+ support smart diagnosis: press and hold the power button, then within 3 seconds press and hold the temperature button while holding your phone speaker against the smart diagnosis icon (or use the lg thinq app over wi-fi on newer models).

We stock the top-30 wear items for this brand on the truck, so most first-visit repairs close same-day. We're EPA 608 certified for sealed-system and refrigerant work, licensed and insured in Minnesota, and every tech carries a factory diagnostic laptop for brand-specific service modes. If the model is out of parts support, we'll say so on the first call and refund the diagnostic — that's the honest read on a repair-vs-replace decision, and it's the same read we'd give a family member calling about the same dryer.

FAQ

Minneapolis questions, answered

  • What does D80 / D90 / D95 mean on an LG dryer?

    Vent restriction codes — the dryer measured exhaust airflow and decided the duct is 80 / 90 / 95% blocked. Clean the full vent run from dryer outlet to exterior cap. $185 add-on for cleaning, or DIY for free. Ignore D95 and the heater burns out next.

  • What does tE1 or tE2 mean on an LG dryer?

    tE1 = outlet thermistor open or shorted; tE2 = inlet thermistor. $225–$285 swap, usually paired with a vent inspection because heat soak from a restricted vent shortens thermistor life.

  • How do I clear CL on an LG dryer?

    CL is Child Lock — hold the Child Lock button for 3 seconds. Not a fault, just a setting.

  • How do I run LG Smart Diagnosis on a dryer?

    Press and hold Power, then within 3 seconds press and hold the temperature button while holding your phone speaker against the Smart Diagnosis icon. Or use the LG ThinQ app over Wi-Fi on newer models. The app decodes stored fault history.

  • How much does LG dryer repair cost?

    Most LG dryer repairs land $245–$485 all-in. Thermistor $225–$285. Door switch $225–$345. Heater + thermal fuse $385–$525 (add $185 vent cleaning). Gas valve coils $245–$345. Main control board $385–$525. The $149 trip fee is waived when you approve the repair.

  • Do you service LG DLEX and DLGX steam dryers?

    Yes — LG dryer repair service runs across the Twin Cities every weekday, including condos, townhomes, single-family, and small commercial. There's no separate trip charge by neighborhood or ZIP inside the city limits. Property managers and landlords welcome; we handle COI and split-billing on request.
