: Negative Temperature Coefficient (NTC) thermistors are pressed against the underside of the cooking glass surface and attached directly to the IGBT aluminum heatsink. If temperatures cross threshold safety limits, the MCU instantly stops PWM generation. Component Specifications and Substitutions
: Often indicates a shorted IGBT or a failed bridge rectifier. If the IGBT is replaced, always check the resonant capacitor and the gate driver circuit (transistors like S8050/S8550) to ensure the new IGBT doesn't fail immediately. chk-v9.04g circuit diagram
