If I could rate this 0 stars I absolutely would..... I purchased this last summer and it worked great for the first month and then it started malfunctioning... turning on and off on its own, changing settings and temp on its own. When it started to do this the buttons and remote would stop working. The only way to get them to work was to unplug or reset the plug. It would work for a couple hours or maybe a day and then start acting up again. We made it through the summer and stored it away for the winter. When I put it back in the window in late May it was working perfectly. Not doing any of the crazy things it was doing last summer. Well the last week it started shutting off on its own and as of today it is not working at all. When I unplug it and plug it back in it turns on for a quick second, flashes what i assume are error codes (good luck trying to find any info on what they mean) and shuts off. It will not do anything after that.... most expensive piece of garbage if Im honest.
