Chk-v9.04g Circuit Diagram

The MCU monitors temperature sensors (thermistors) under the glass and on the IGBT heatsink.

If you are troubleshooting a CHK-V9.04G board, check these components first: Usually shorts out, causing the main fuse to blow. Bridge Rectifier: Often fails alongside the IGBT. Resonant Capacitor: chk-v9.04g circuit diagram

The AC mains (usually 220V) enters through a fuse and an EMI filter. It is then rectified by a bridge rectifier into high-voltage DC. Resonant Tank & IGBT: This is the "engine" of the board.
