Maybe it should be a shunt resistor and I'm missreading the color code in it? I just cant immagine a 28 Ohms in series to a 1500 W motor supply lines.

I concur with your doubt. This fatty boy looks like a current sensing shunt resistor, which, as you said, is normally small Ohms. Check carefully the original one.
Swake:
No live on the pin that is triggering the gate of the Triac?
That Gate is not shorted to GND or +5 ?
The more pulses from the sensor, the quicker it runs, the shorter the pulses to the triac to reduce it's speed. Inversely as long as there is no signal from the sensor it should think there is no (slow) rotation and the gate should be triggered all the time to give it more power. Of course this cannot last long before the motor burns, but it should at least try for a second or so.
Marek85:
Yep nothing only current consuption shows some life.
But the good news is that I was able to order the board yesterday from that Dannish spare part shop you sent. With shipment it was 150 EUR 😂 damn I hope this board will do the job 😅
Swake:
Not a rip off at all :wtf:
You might be able to compare some things and repair the 'old' board after all.

Does a brand new mixer cost more than that shipment cost? :wtf:
