I have the exact same problem as this guy, and I'm wondering if the
solution is the same.
It might be, or it might not be. You will need to measure the pressures in the rear
system and see what is going on. If you dont achieve the specified pressures, then
you have either a lack of refrigerant OR you have a mechanical problem with the
compressor, valves, etc.
If you know how to do it, you can buy a can of refrigerant with a pressure gauge,
and you can attach it to the vacuum side of the compressor. Add refrigerant
very slowly until your pressure measurement reaches the value mandated. (You
can find this on your can of refrigerant or you can find it from the data for your
particular application)
If you have adequate cooling, then you guessed correctly.
The more certain way is to take this beast to a competent refrigeration mechanic
and avoid the mystery.
