Try changing out your air filters if that don't work try cleaning evaporation coils. If that don't work get ahold of your local HVAC shop they will take care of it.

If this is a ductless split call a tech! The ductless split systems can be a troublesome unit to diagnose. A few things to try. Clean air filters and ensure coil behind is clean. And build up or debris on blower wheel (indoor fan blades) will cause unit to fault. Turn off power at breaker or disconnect and clean (with water hose and medium pressure) the outdoor coil. Be sure you will not damage outdoor coils fins with too much water pressure. Turn power on. If this simple service don't do it again, call a tech! Be sure to ask if they have someone who is experienced with mini split systems and be patient. Even the best technician will need to call carrier for tech support.

have you tried to call carrier to see if there is a universal remote that may be programed to your mini split system?
