If your AC suddenly stopped working, check the power supply, the plug, the switch, and the circuit breaker.
Replace the remote batteries and try again
Set the AC to cool mode and lower the temperature
Clean the air filters if they are dirty
Check for ice or water leakage and turn off the AC to defrost
Clear dirt or blockage around the outdoor unit
Call a technician if it still does not cool, makes a strange noise, or smells. I hope this gives you an idea of what to check before calling a technician.
