What Does Error Code E3 Mean on a LG Dryer?

Motor or board sensing error — drum motor not detected running.

E3 indicates the control board isn't seeing expected feedback from the drive motor circuit shortly after starting. The drum may hum and stall or not move at all. A seized motor, a failed start capacitor (on belt-drive models), or board relay failure are the usual suspects.

What Causes Error Code E3?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Drive motor failed or seized 40% of cases
  2. 2
    Board relay/sensing circuit fault 30% of cases
  3. 3
    Belt broken so the motor trips its overload 20% of cases
  4. 4
    Harness fault between board and motor 10% of cases

How to Fix LG Dryer Error Code E3

🔧🔧🔧 Advanced DIY Est. time: 1–3 hours
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check the belt and drum

    Unplug the dryer and turn the drum by hand — it should rotate with even resistance; a free-spinning drum means a broken belt.

    🔩 LG dryer belt ($10–$25)
    ⚠️ Unplug the dryer before opening the cabinet.
  2. 2

    Test the motor

    With the belt off, spin the motor pulley by hand (it should turn freely) and check winding continuity; a seized or open motor needs replacement.

    🔩 LG dryer drive motor ($80–$160)
  3. 3

    Replace the main board

    If the motor and belt are good, the board's motor relay has likely failed.

    🔩 LG dryer main control board ($90–$200)
    ⚠️ Unplug the dryer before swapping the board.

How to Reset Error Code E3

Unplug for 10 minutes, then restart. A humming-then-stop pattern means stop retrying — you'll overheat the motor windings.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

Frequently Asked Questions

Can I keep using my LG Dryer when error E3 appears? +
It is not advisable. The dryer may still power on, but running it while E3 is active can worsen the motor fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes E3 on a LG Dryer? +
Across reported LG dryer repairs, the most frequent is drive motor failed or seized (40% of cases), board relay/sensing circuit fault (30%), then belt broken so the motor trips its overload (20%). Check them in that order before replacing any parts.
E3 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E3 fault; if it returns, the motor problem is still present. Move on to the physical checks — check the belt and drum, then test the motor — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.
How much does it cost to fix LG Dryer error E3? +
A DIY repair typically runs $10–$200 in parts, versus $200–$400 for a professional service call, so handling it yourself saves around $190. Expect the work to take 1–3 hours.
