LG Dryer Error Codes: Quick Fixes for Homeowners
When your LG dryer flashes a cryptic error code, the first instinct is to panic—but most issues are solvable with a few tools and a systematic approach. Below are hands‑on steps that let you diagnose and often repair the problem without waiting for a service call.
Identify the Code and Its Category
LG dryers group error codes into three families: F0, E0, and tE. The first letter tells you whether the fault is sensor‑related (F), electronic (E), or temperature‑related (t). Write down the exact code (e.g., F07, E1, tE1) before you start troubleshooting.
- F‑codes usually point to a faulty door switch, moisture sensor, or drum speed sensor.
- E‑codes involve the main control board, communication lines, or power supply.
- tE‑codes indicate temperature sensor or heating element problems.
Having the code at hand narrows your search to the relevant components, saving time and reducing guesswork. For a deeper dive into each code, you can read the full explanation.
Common Culprits and Quick Checks
Door Switch – A dryer won’t start if it thinks the door is open. Open the door, press the switch manually, and listen for a click. If the click is absent or feels mushy, replace the switch (usually a $10–$20 part).
Lint Build‑up – Excess lint can trick the moisture sensor into thinking the load is still wet, triggering
F07ortE1. Remove the lint screen, clean the dryer vent pipe with a vacuum brush, and wipe the sensor bar inside the drum with a soft cloth and a dab of rubbing alcohol.Power Supply – Many error codes disappear after a hard reset. Unplug the dryer for two minutes, then plug it back in. This clears temporary glitches in the control board.
Thermal Fuse – If the dryer stops heating and shows a temperature‑related code, locate the thermal fuse on the exhaust housing. Test it with a multimeter; continuity means it’s good. A blown fuse must be replaced—don’t bypass it.
Moisture Sensor Pads – The pads can become coated with fabric softener residue. Gently scrape them with a toothbrush and wipe clean. Re‑run a short cycle; the code often vanishes.
When to Call a Pro
If you’ve verified the door switch, cleared lint, reset power, and the error persists, the fault likely lies deeper: a failing control board, a broken drum speed sensor, or a damaged heating element. These components require specialized testing equipment and safety precautions (high voltage). Attempting a DIY repair on them can void warranties or cause injury. In such cases, schedule a technician who can diagnose the board’s communication lines and replace parts safely.
