Quick answer
Code 5 on an LG cooktop is a display error. The listed fix is a Power ON/OFF press and a 30 second breaker reset.
Model compatibility: LG reuses codes across series and model years, so 5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
