The oven door lock did not lock or unlock as expected, often at the start or end of self clean. A faulty lock motor or switch, or something blocking the latch, is the usual cause.

Likely causes

Listed from most to least common.

  1. Door lock motor failed
  2. Door lock switch not reading correctly
  3. Latch blocked by food, foil or a misaligned door
  4. Loose wiring to the lock assembly
  5. Control board fault

How to fix the F10 code

Unplug the oven or switch it off at the breaker before removing any panel or filter.

  1. Step 1: Let the oven cool fully

    If the code appeared during self clean, wait at least 1 to 2 hours for the oven to cool. Do not force the door open while it is locked.

  2. Step 2: Clear the code

    Press Clear/Off, then try the function again.

  3. Step 3: Reset power at the breaker

    Switch off the breaker for the range for about 30 seconds, then switch it back on. The lock often resets and releases.

  4. Step 4: Check the latch area

    Once the door opens and the oven is cold, check that nothing is blocking the latch slot and that the door closes flat and evenly.

You'll need: Flashlight.

Parts that may need replacing

Check your model number on the label inside the door or on the back before ordering.

When to call a technician

Call a technician if the door stays locked after the oven is cool and the power has been reset, or if F10 keeps returning. Do not try to bypass or pry the lock.

A typical repair for this code costs $150–$350 in the US, including parts and labor. Prices vary by area and model.

Common questions

›My LG oven door is stuck locked after self clean. What should I do?

Let the oven cool completely, then reset power at the breaker for 30 seconds. If it still will not unlock, book a service visit rather than forcing it.

›What does F20 mean on an LG double oven?

F20 is the door lock failure for the lower oven. F10 is the same fault for the upper or main oven.
