Thank you my friend explained to you. The fridge worked fine. Only I was freezing all the evaporator tubes and not cooling down opened and provided resistance. It works well for me. That is to say it has continuity then check the thermal fuse and it was fine. When I test the room or temperature sensor, it shows me that it has 1.8 k. I bought a new lg fridge sensor, I think it marks 4.0 kh when it connected, it didn't do anything just turn me on the internal led lights and the display outside.
Friend already resolved. The problem was in the connector where the room sensor goes one of the pins that the room sensor receives was not making contact, that is to say the two pins that the connector receives one of it was bent and did not contact. Really thanks for your help maggiber. . He clarified my understanding when he said you would check the wiring
