Assuming the compressor is sized correctly( and usually they are) There are a couple of fairly easy things to check.
1.) The compressor unit.
Are the fan(or fans ) operating. Some units have two condenser fans and will operate with only one until the temperature gets too high for it to keep up.
Is the coil clean. A dirty coil can cause unit to fail too keep up in high temperatures.
2.) The evaporator unit .
Same as condenser unit . Are the fans all working
Are the coils clean.
3.) Defrost Timer. Is the time set correctly .
Is the unit defrosting during low usage time periods.

Hope this helps

There HAVE to be a thermostat to cycle unit .Is there a sight glass on the liquid line .If there is normally you charge it up until you see no more bubbles in the sight glass.
There is never a constant pressure reading because pressure depend on outside temperature .
Thermostat for freezer will not look like regular thermostat.
I will be in the evaporator section

Hallo Please send me a picture of the compressor and one of the sticker on the compressor and i'll give you the specifications and compatible suggestions. Regards

first of all, there was a reason why the old compressor locked up and without finding out the reason why the problem is following the new one. The hissing that you are talking about is it coming from the compressor? If it is it sound like it is the internal pressure relief going off, this noise should come and go. Yes you do have a problem, and it could be a number of reasons but you need to find out the right one or you will spend more money than it would have cost a service man to repair, at least if he did it you could go back to him.
1. Was compressor burnt at time of lockup?
2. did you change the drier?
3. is it correctly charged?
4. Is TXV feeding properly?
let me know and maybe i can help.
