If you are repairing a board with the CHK-V9.04G marking, focus on these critical components commonly available through electronics suppliers like DigiKey Electronics : Component Category Common Parts/Labels IGBT (e.g., FGA25N120) Switches the coil current. Rectification Bridge Rectifier Converts AC to DC. Protection Fuse (10A-15A) Protects against over-current. Filtering 5μF or 0.3μF Capacitors Smooths DC bus and handles resonance. Control PWM IC / MCU Brain of the unit. Common Repair Scenarios

: Uses the PWM signal to switch an Insulated Gate Bipolar Transistor (IGBT) . This high-power transistor switches current through the induction coil at high frequencies to generate the magnetic field. chk-v9.04g circuit diagram

The circuit is generally divided into several key stages that manage power conversion and user interface: If you are repairing a board with the CHK-V9
