The board is designed to monitor several parameters to ensure safe operation: chk-v9.04g circuit diagram

The CHK-V9.04G board typically follows a standardized architecture for electromagnetic heating:

Power MOSFETs/IGBTs and relay triggers.

: Usually points to a faulty thermistor or a sensor connection issue on the main board.

Test the optocouplers, as they frequently blow to protect the controller. Explain the this story was inspired by

Desolder the IGBT and test with a multimeter in diode mode. Replace the driver transistors (S8050/S8550) alongside a blown IGBT.

Flip the board over and inspect the solder joints underneath the IGBT legs and the bridge rectifier for fractures or signs of melting. Phase 2: Static Multimeter Testing (Power Off) Test the optocouplers, as they frequently blow to
