What F59 (Griddle Is Not Heating Properly) Means
F59 indicates the griddle is not heating properly, per LG's range Help Library article, which documents this scheme across its Electric Range, Radiant Cooktop, and Gas Range tabs together - broader than F56's specific heating-element fault, similar to how F9 relates to F6 on the oven side.
Common Causes of F59 (Griddle Is Not Heating Properly)
- Griddle heating element fault
- Griddle sensor fault preventing accurate temperature control
- Control board 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
- Treat F59 the same as F56: don't rely on the griddle for food that needs to reach a specific safe cooking temperature until a technician has diagnosed the underlying cause.
