Unplug the frig, defrost. and I opened it using a video on YouTube and everything worked out for me, it has been three days since I connected it and until now it works very well it has not frozen.
But I have another problem, which I have to fix. When I ordered everything. I did not notice that the tank filter is burst, when I froze it froze so much that the water tank along with the filter burst, and I will need to order it to change it.
