Blindly replacing fuses one after another will finally give you a completely charred board. And a lot of blown fuses.

Usually, it's the main IGBT that fails in an induction stove. And the reason is poor cooling, the cooling fan air inlet blocked. The failure of the IGBT can be / can lead to other transistors on the board being damaged.

Hopefully, replacing the IGBT should solve the problem. But check the other transistors for damage.

Connect a 500W incandescent bulb in series with the cooker when conducting further tests.

And be very careful. You are working on live power and 400 Volts.
