To answer a previously asked question, if the system has lost its
charge and air has entered the system then you will need to vacuum the
system to remove any moisture that might have gotten into the system.

Yes, and it should be professionally leak checked at the same time.

Of course. It hardly bears saying that if the fridge leaks all it's
gas it does need to be checked for leaks :-)

Dyed R134 can be used as a charge, and leaks easily seen with a UV
light that comes with the dye kit. Don't need a sniffer.
Here's one.

I've used the Inter-Dynamics dye a few times, but the last time I
looked for that dye I had to get it from e-Bay.
I've only done automotive.

I had a couple of jobs maintaining a small fleet of vehicles. We use
the refrigerant with dye any time we had to re-charge a system. It
didn't fix anything by itself but it sure saves time when it came back
for service :-) "Eh! Look it's all red there". :-)
