If code 1 comes back after the reset, call (415) 223-7887 from San Francisco or elsewhere around the Bay. The LG cooktop repair page covers the work. Keep the model number nearby and be ready to say what you tried.
Model compatibility: LG reuses codes across series and model years, so 1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
