If you are working with a board, here are the usual suspects for failure: Likely Faulty Component Dead (No lights) Main Fuse (F1), Bridge Rectifier, or SMPS chip (VIPer12A). Blowing Fuse Instantly Shorted IGBT . Check the Bridge Rectifier as well. E0 or No Pan Detected
:Mains AC (typically 220V) enters through a fuse and an EMI filter. It is then converted to DC by a high-current Bridge Rectifier . This DC voltage is filtered by a large capacitor (often 5µF) to provide a stable bus for the induction coil.
The CHK-V9.04G features several protection circuits that trigger specific error codes when issues are detected:
This is the heart of the induction cooktop's heating system.
