What F52 (Griddle Sensor Short) Means
F52 indicates a griddle sensor short was detected, per LG's range Help Library article, which documents this scheme across its Electric Range, Radiant Cooktop, and Gas Range tabs together - a related but electrically distinct fault from F51's general sensor error.
Common Causes of F52 (Griddle Sensor Short)
- Griddle sensor circuit has shorted
- Wiring damage causing a short in the sensor circuit
🔧 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
- A shorted sensor circuit is an electrical fault, not just a bad reading - if it returns after a breaker cycle, avoid using the griddle zone and have a technician inspect the wiring rather than continuing to test it yourself.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
