albert: in the area where the stove is right now there is a lot of power issues that the company is working on to get fixed but with the war situation is not easy to go and get it checked but your are right the current can be checked but right not it is not the right time to do. thanks for your input and have a blessed day

Mike: greetings
when you have a short on board the parts will blow up and get burnet but when replacing the faulty parts with good ones and not sure if the short is gone you connect it to a current limiter so if there is short the light bulb will come on brighlty saving all the new parts you installed but if it went bright then went dim there is not short left on board and it is safe to power the power supply through 220 volts. you can search it online for more information and you can build a cheap ones to help you in your repair. have a blessed day

Maybe we could measure the exact current that flows at inrush switch on moment, and the current when the stove is at maximum heating to determine the here right needed better protecting fuse?

Could you expain how the testing with a bulb works?

I asked the same question myself and I checked the original fuse on a same working board and it was 3:15 amp rate. Not really sure what happend here and why the fuse did not protect the board. I did not want to take the rist and replacing it with a 2 amp fuse so I rostored the fuse to its original value and hopped for the best. have a blessed day

Odd thing here though is that the original fuse didn't protect the primary circuit when the current got too high, so badly that even the wider copper tracks on the solderside burned open? Why it probably is questionable that the fuse rating is the right one.
