Without seeing the unit,
1 - the condenser fan (which is in the outdoor unit) could be blown. This would cause the unit to go off on high head pressure.
2 - it could be low on refrigerant, which makes it do nothing but blow room temperature air around. The unit would go off on low pressure
3 - the filter is dirty, blocking the cooling
4 - the compressor could be shorted, or a corroded wire somewhere that feeds the contactor
Mr. Slim Ductless Splits are the best on the market and should only be repaired by a trained technician.
Hope this helps.
