What F56 (Griddle Heating Error) Means
F56 indicates a griddle heating error, per LG's range Help Library article, which documents this scheme across its Electric Range, Radiant Cooktop, and Gas Range tabs together - a fault with the griddle zone's actual heating performance.
Common Causes of F56 (Griddle Heating Error)
- Griddle heating element has failed
- Griddle element wiring or relay fault
🔧 One Safe Check You Can Try
Turn the circuit breaker for the range off, wait 30 seconds, and turn it back on.
⚠ Why You Shouldn't Go Further Than That
- If F56 returns after a breaker cycle, don't rely on the griddle zone for cooking that needs to reach a safe temperature until it's repaired - a heating element fault means the surface may not actually be as hot as it appears to be set.
