Thank you. I disassembled and measured the two bimetals, the resistance and the NTC sensors below (I didn't check the refrigerator one. All of that works well. Also the thermostat in the bottom cabinet. The forcer pulls (and in the right direction, towards the door). I changed the engine because the previous one was dismantled by a coil cable) I do not know if it is of the same power, I do not remember the previous one that the wind was pulling, this one pulls but I feel the refrigerator very silent now, nor the motor that starts and cuts . (It freezes well above, and you feel the smooth vibration that seems to run the engine, but now you can't hear it). Will the problem be the card? Another question: The general electric refrigerator no frost turbo plus is the same components as the Mabe? Other: How does the potentiometer regulate the temperature below? If cold air passes through the ducts (they are uncovered). Thank you very much for your help and time. Please tell me if I should qualify or something for each answer that I am not doing. Goodnight.
