My air conditioner also sometimes gives out the wrong setting that I set it. It happened that instead of cold air, it gives out warm, and instead of warm cold. As always, I tried to fix it myself, but in the end I only made it worse. I had to call the masters from https://www.socool.sg/. They fixed it and everything worked well. When I saved up a new air conditioner, there were also knocked down settings, called them again. In general, always buy good air conditioners, so that you do not have to worry about their settings and do not call the masters once again. Good luck to you and your air conditioner LOL.
