What F36 (Transistor Error) Means
F36 indicates a transistor error, per LG's range Help Library article - a fault within the induction cooktop's power electronics (the inverter circuitry that drives the induction coils).
Common Causes of F36 (Transistor Error)
- Inverter/power transistor fault in the induction control electronics
- Overheating of the power electronics
🔧 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 F36 returns after a breaker cycle, this is high-voltage power-electronics work inside the cooktop that needs a technician - not something to keep resetting repeatedly.
- A failing power transistor in the induction system can be a genuine electrical safety concern, so stop using the affected cooking zone until it's inspected rather than continuing to cook on a burner throwing this fault.
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.
