I bought 2 of this same unit both started having problems within a year .
One unit ,when you press the OFF button ,the control panel goes to a  "Co" mode then when you press OFF again the panel goes to ENERGY SAVER mode ,press OFF a third time then it will turn off.

The second unit  I have , when in DRY mode the unit runs at HIGH fan speed.
The coils on the bottom two rows  freeze up but only half way across in COOL mode and DRY mode.
