Hi, I have a no frost whirpool that works well for two weeks and then the air passage is blocked down with ice. I put a separate tiimer and he does the same

It is not understood about the timer apart if the timer you put is not connected to the equipment and the resistance, and it only makes you stop the compressor does not work, you have to connect the resistance also if it is not blocked

good night I have the whirlpool wrw51x1 refrigerator that repaired the plate, after a month the freezer is fine but does not cool the bottom. If the cold defrosting sensor goes to 5.3k, lowering the temperature to 3.7k and giving it heat, it goes to 2.6k which would be almost correct, I also tested the other sensor and I don't care. What I could not prove is the hot melt that has to give me continuity. Sorry but since the question is open. greetings and thanks
