LG range or oven code F56: meaning and exact next steps

F56 means a Griddle Heating Error — LG's own wording. This answer applies only to LG electric and gas ranges and wall ovens. LG documents radiant-cooktop codes separately in the same article; griddle, induction and sous-vide codes apply only to models with those features.

On the covered LG range or oven, F56 means a Griddle Heating Error — LG's own wording. First, note whether the griddle warmed at all before the code. Then: for F56 LG's single step is the breaker off for 30 seconds and back on, with no CLEAR/OFF key involved — LG's own sequence.

Before you touch a setting

Record this first — changing settings destroys the evidence

  • That the code reads F56 and not F51 or F59
  • Whether the griddle gets warm at all
  • Whether the plate was removed and replaced recently
  • Any spills near the griddle connection

Model-specific

What is true of this model and not of its siblings

What the griddle is
Some LG ranges have a center griddle with its own element and sensor. The control watches the griddle's temperature against what it expects and shows F56 when the heating does not match.
Seating matters
A griddle plate that is not fully in place can sit off the connection or the sensor, which gives the control a reading it does not expect. Check that the plate is flat, undamaged and fitted as the manual says.
Spills
Grease and sugary spills bake onto a hot surface and can insulate the element or the sensor. Clean the griddle when it is cool, using the cleaner LG's manual allows.
A related code
F51 is the griddle sensor error and F59 the griddle not heating properly. A technician can tell them apart by reading the sensor, so give the exact code.
When to stop
If the griddle smells of burning, smokes or only some of it is hot, switch it off and let it cool, then book service.
Records
Write down how long the griddle took to warm before the code and whether it ever reached temperature, so the technician knows if the element or the sensor is suspect.
Cleaning a griddle safely
Wait until the griddle is fully cool, remove loose food, then wipe with a damp cloth and a mild cleaner the manual allows. Do not use abrasive pads on the coating, and do not immerse the griddle if it has a connector. Dry it before use. A clean, dry connection area is less likely to fault.
Using the griddle after the code
Do not switch the griddle on again until it has been checked, as an element that is partly failed may overheat in one area. Use the burners or the oven for cooking meanwhile.
