Mini split systems are ductless and consist of an outdoor compressor unit and indoor air-handling units, providing individual room control. PTAC systems are typically installed through a wall and have a single unit for both heating and cooling, often used in hotel rooms.
the compressor is not running. Check your breakers.

Low pressure relay is bad! Check freon pressure, if it falls too low, the compressor will not run (installed for safet of compressor)
With an ohm-meter. Check for continuity in the RUN and START windings, and also from the terminals to compressor case for shorting. There should be continuity in the windings and no continuity from windings to compressor case.

Is it a central unit? check and see if the fan and compressor are running in the outdoor unit. The system may be low on freon or the compressor may not be running. It is best to call a qualified HVAC technician.
Up to 2 forced air units to one compressor unit.
A PTAC AC unit is a type of air conditioning system designed for residential use that offers key features such as individual room temperature control, energy efficiency, and easy installation. The benefits include cost savings on energy bills, quiet operation, and the ability to heat and cool a room efficiently.
Remove and contain the refrigerant; if you suspect the compressor motor has a burnd-out; treat the refrigerant as contaminated. Disconnect the lines from the compressor, including electrical, replace the filter, and compressor, purge the system, check for leaks, vent the nitrogen, do a pull down below 500 microns, replace refrigerant, and oil. do a run up check pressures, and temp.
