Hello Pablo, for the image nothing seems to have problems, my suggestion is that you do not disconnect the refrigerator anymore and hope that it reaches its maximum temperature, so that the thermostat starts, to censor the real temperature. Do not expect this to happen right away, it may take up to 24 hours for a thermostat to begin to perform its functions well and the refrigerator for up to 72 hours to recover, from the loss of cold suffered during the time the site moved. However, if you want to know if the thermostat census, either the temperature, and if you connect it correctly, you can take it to the minimum of its sensitivity, also reducing the scale in your working range, turning the control knob, to the left , contrary to the hands of the clock. Example if you have it regulated in # 4, lower it to # 1. When you feel that it stops, if even at that point the compressor continues to work, then force that stop a little, thus forcing the compressor to stop, also turning and forcing the left turn, by moving more in that direction, to the control knob, until yes, I heard that the compressor stopped, then re-manipulate the knob but this time, turning it to the right and place the graduation in the range number # 1. If you do not listen, when you reach that point, the compressor tries to start immediately, and that the entire refrigerator is left dead and only the interior lamp works. This would indicate that the control has good sensitivity and that everything is well connected, so you only have to wait for the working temperatures of the refrigerator to stabilize, after 72 hours. If, on the contrary, when the stop is forced by manipulating the control knob, to the left, and said compressor does not stop, in that case it would be incorrectly connected, the thermostat. But if you force the stop and it does well, but try to start the compressor right away, in that case the new temperature control or thermostat would also be damaged and should change it. Your refrigerator during normal operation, you have to freeze almost the entire rear wall where the connected thermostat carries the bulb and can reach up to half a centimeter the thickness of ice or frost, which is formed there, after that limit, the cold temperature begins to be lost , because the heat exchange with the evaporator plate of that conservation zone would already be lost.
