Hello good night, I have this model of refrigerator in my workshop, and I can not find the problem, I tell you this refrigerator I have changed the temperature sensor 10k, bimetal, defrosting resistance works well, the problem is perfect to perform about 3 Thaws then all the LEDs begin, this model has a led interface board, alarm LED and 3 freezing level, the ones that start flashing are the alarm and the 3 freezing level, it is constant do not stop flashing. I have done the measurements of sensor, bimetal, resistance, it is more until I have changed the plate, the strange thing is that it works normal, that is to say it cools well, both the freezer and the refrigerator, the engine stops and starts well. Please I need your Help, thanks. Can it be a bad communication between the interfece board and the motherboard? Thank you
