Power switching and loads
Faulty gate driver transistors (e.g., S8050/S8550) or a dried-out 0.3uF resonant capacitor. Fan Not Moving Check for 18V supply or a faulty Q1 (S8050) transistor. chk-v9.04g circuit diagram
Monitors the temperature of both the IGBT and the cooking surface to prevent overheating. Fan Control: Operates a DC fan to cool the internal heatsinks. Pan Detection: Power switching and loads Faulty gate driver transistors
