The refrigerant is flashing in the compressor, not the evaporator.  I think it's severely overcharged.  You could remove refrigerant little by little until the frost leaves the compressor and then see how it cools.  But, I have no experience with expansion valves.  Maybe someone else will have a better answer.

I don't think you can release R502 into the air legally, must use a recycling tank. Best to purge the system and re-charge. Looks like he tried to re-charge based on the R502 pressure/ temperature chart but either the compressor failed, or there is something clogged in the system.

what does the flashing refrigerment mean?
and no u cant legally discharge the 502 and well this guy doesn't think he has any left  his son did it    all i know is i adjusted the expansion valve which is  the AX valve   as it adjusts the 16psi from the preset of 25psi  the other set screw you see that's the hopper one and u leave it at 61psi


how does the compressor fail?
how does something get clogged in the system

The compressor can just become inneficient, fail to pump up the refrigerant to a high level, or leak refrigerant internally. Oil can get trapped in the cap tube, or freeze up, or contaminents can get past the dryer.

Too dang much gas in that thang. The best way to do it is get a reclaim machine with a dedicated tank and remove all the gas. Put in the proper amount by weight using same machine OR do it by taking the pressure to 5 psi and look for bubbles in the sight glass.
