Its may be the thermistor is defective or out of range or the board itself, the unit will not operate unless the defective part is not replace.

a/c units have ways of protecting their major components. if you have a freon leak it could be shutting down on low pressure safety switch. or it could be overcharged with freon and be shutting off on high pressure, although high pressure safeties usually have a manual reset. therefore a low pressure
problem is more likely

if no cold blowing,evaporator is not working,have you ever heard compressor is running,check this out,no compression of course you dont have cool on evaporator.if the compressor is running check the oprating current,if still have enough freon charge,if not running check thermostat reset setting on the coldest,ifn still not run check overload relay on panel control reset lever to put back compressor to run,check condensing fan if working,if not check also over load protection,this should be done by ac tech nician.have a nice day,dont gorget to rate me, thank's

Not sure the make and model of your equipment you have there but sounds to me like your control board is trying to tell you it is bad.
