Poor contact between magnetic knob and sensor surface

How to Identify: Knob requires unusual pressure, jumps between settings, or response is intermittent; sometimes fixes temporarily with added material for better contact

Part: Magnetic knob contact surface / induction cooktop sensor

Underlying control sensor or board fault

How to Identify: Dial appears intact but turning it has no effect on cooktop settings; other controls also unresponsive

Part: Cooktop control board or sensor
