Re: regarding gas pressure
Ok lets see how i can help you. If the units low on gas, suspect a refrigerant leak!! 2nd, what refrigerant it's using? I can't tell you operating pressures if you don't know the refrigerant. (usually the label on the indoor unit right side says refrigerant charge and type.) 3rd desired temperature for cooling is about 68-72 F that's about 20-22 Celsius.

If after reset the A/C cools then the fault seems related to the thermostat or the cut off pressure switch or load cut off.
However is there is no cooling at all the compressor and the gas pressure- check for leak if gas is absent.- must be checked .
If compressor is suspect you must check the estimate and decide whether it seems better to scrap and buy a new one.
Check it's in cool mode and temp setting is 3 degree less than room temp Check compressor is working with required pressure.60 PSI@ 98 degree Fahrenheit of ambient temp.If less pressure or no pressure, gas leak. Arrest leak and recharge gas.
Check that the fanmotor can spin freely. If not, can be caused by seized bearing on left side of fanblade, or foreign object, insect nest stuck in fanblade. If however it spins freely, check that fanmotor is being supplied with voltage (you sound technically capable of operating a volt meter). If power is supplied, fanmotor is faulty and needs replacing. If no voltage, problem lies with the pc board. If you know someone who is capable let them check the relays on the board. Also you can check that all plug on connectors are making good connection.
-If both compressor and fan motor starts and stop, thermostat is the defect. - If only the compressor check for your outlet no sign of discoloration, check the voltage if normal, check the defective overload protector of the compressor it its external, or compressor itself is defective
