hello folks. hope you're all cool ...
our fridge was deiced a few weeks ago, probably a sensor or motherboard is defective, and yesterday again needed such de icing.

The model is a two doors, apparently equipped with 4 sensors located two on upper level of coils, two on lower level, one on each side at each level, aluminium wrapping, Alu foil not opened, so there copuld be more than one sensor on each location. Another sensor on the tubing, above the coils level.
glass heater on bottom. Heater disconnected seems not open. probably doesn[t receive power when needed.
The fridge had an external overload protection, and such apparently went bad for a local surcharge on electrical system in building. BUT such option was not verified.
Question is, which sensors should we take off, or check before with or without power on? and Could the motherboard have been "burned" even if apparently nothing is visibly burned inside. picts or more info welcome..
