I put this air conditioner in my window on June 1st,  2020 I had absolutely no issues whatsoever it worked great. But then, today it started making extremely loud noises. I checked everything out, I checked the manual, The noise it's making I cannot find it in the manual. I think the motor is going in this That's what it sounds like. I have not used the Wi-Fi I haven't really had a chance to even try it. I am not happy with this air conditioner because I need an AC to breathe I have lung issues.
