Samsung refrigerator freezes but does not refrigerate

Good morning, I have the Samsung refrigerator model Rb29ferndww of 2014, and the problem is that it freezes well but does not refrigerate, I have checked the temperature sensor brand 4.8kohm, the hot melt gives continuity 0 ohms, the fan I bought it with 12 volts and it goes well, I have a lot of doubt with the following: the bimetallic sensor is in series with the resistance and I measure it at room temperature both in series and it gives me 360 Ohm which means that the bimetallic sensor is closed, is this correct or wrong , please I need reliable information, why I have seen tutorials and they say the bimetallic must be open at room temperature, when p who sells the Samsung bimetallic sensor da47-00243k tells me that at room temperature it is closed. I do not know which one is valid, attached photo of the resistance piece in series with the Da47-00460A bimetallic sensor. Please, I need help if someone can with the service manual I would greatly appreciate it. Greetings.

Hello, the hot melt, it has to give resistance 1 or 2 Ohm, 0 ohm, it is open, it is not continuity, it must be replaced, you already comment Regards

But it gives me continuity, if it were open I would not mark the 360 ohms of the resistance in series with the bimetal.
Thanks for answering

clarify, you refer to the hot melt that you say gives 0 ohm continuity

You're right, in my previous comment I confused it with the bimetal,
But the hot melt gives me continuity. With less than 1 ohm.

The Da47-00243K, is a defrosting thermostat, a bimetal .... https: //www.youtube.com/watch? V = kQ4YOjGq6MQ

A bimetal should mark open or nothing ohms, if you mark change it

Hi Fermín but the one in the store says it must be closed is the da47-00243k.

If it is bimetal it should not be closed, at a low temperature if

Thank you for responding, and that is the bimetal function, but I have doubts that this refrigerator is controlled by a microcontroller, but I do not understand who sells this bimetal da47-0243k, which says it is closed at room temperature.
Thanks for your help.

Well there are bimetals that work in reverse, but this as it goes in series with the resistance is illogical to work backwards, I explain? when frozen is it open? It may not be, perhaps it is for another function, but if you are sure that it goes in series with the resistance, it cannot be closed at room temperature, because it would not heat the resistance since being frozen would open, or only remain closed? comment, regards

Thank you very much for commenting, when I solve it I will comment.

It was indeed the bimetal
It has to be open at room temperature and closed at low temperature, in my case it was closed at room temperature. I changed it and it was fixed.
Thank you very much for your help.
