cool on the top but not down I changed the thermostat because it did not work and I added gas but I do not get the temperature in the bottom but if on the top if someone can guide me thanks

Hello, there is a model of refrigerator glasses, which cools everything from the freezer, by means of a force that makes the cold air fence from the freezer towards the bottom, regulated by a thermostat that controls a flap for the passage of it . Pass that covers or the inclination of the equipment causes that the water of consensado pass by until it is frozen and that clapeta

thank you very much for your contributions and it was solved thanks
