Hello people. I hope you are doing well! The problem with this device is that I turn it on, everything works perfectly, it cools. Until it stops cooling. It is as if from the conditioning mode it went into ventilation mode without having activated any control to perform that action. A technician came to see him and, according to him, is the platelet. What do you think? And if it is the platelet, will it be possible for me to change it or is it very complicated? I recently changed the plate of a washing machine and I had no problem. Will the way to change that of an air be similar? Thank you. I await comments and suggestions!
