Hello, my Coolbrand cellar with room for 12 bottles with a variable temperature between 12 and 18 degrees did not turn on and I changed the Peltier Tec1 12705 Plate. Once the cellar was installed, it turned on but the temperature began to increase until it gradually reached 40 degrees, temperature where it remained stable, when opening the door it began to go down until about 30 depending on how long the door was open since it mixed with the room temperature, but when closing the door it increased again until 40, they know what the trouble?
