There is a fairly new (<year I think) Amana wall unit AC in my apartment.
It has been great up until the last 2 days.
---NOw it blows very cold air and displays 60 as the temperature no matter what the thermostat setting is and even if its switched from cool to fan.
---When I switch it off, it still makes a humming sound, like its not really off.
---Amana help desk suggested unplugging for 5 minutes and then plugging in and restarting to "reset". That didn't change anything.
1) Any ideas what is wrong?
2) Any ideas how to fix?
