A blockage in the refrigeration cycle. Any servicing you attempt is at your own risk. I replaced the contactor, had the capacitor checked and it was good but still my unit will run fine for a couple of days and next thing I know the inside unit is blowing warm air and outside unit is not on. When the Freon pressure gets too high the switch shuts off the compressor. Tech said micro-channels are know for that and not a fan of the new technology. If we didn’t notice the sound- the inside thermostat would continue to run and the air would not be cold. There are types of faults and problems with detailed descriptions, possible causes and solutions which may be recommended in the certain situations. The system is over-charged with refrigerant.
