Drier?
Any refrigeration guys here?

Yes to the pictures, that is the receiver and the drier.
The service valve on the receiver is where you want to read your high side pressure.
On the drier, you want to test temperatures on the inlet and the outlet. Right where the stamps for in and out are on the drier.

Since I don't have an accurate way to measure temp, I'll try my infrared. If there's any difference at all I'll just order a other one.

Well I'm glad someone is enjoying it! The guys that know about this stuff should be held in very high regard. They are a cross between genius and wizard. I am neither.

As accurate as I can tell both sides are the same around 96-97* depending on where I take it. I'm hitting the same spot on both ends. Would the temp difference between huge or fractions of a degree?
Edit: I missed the part about where to take the temp. I'll be right back.
97.7 inlet
95.3 outlet

The drier should be the same temperature on the both ends, so that's a good sign. It honestly sounds like it's running properly.... I'm still thinking there's a leak somewhere.
What's the temperature of the air coming off of the evaporator coil? That can help confirm that things are running properly.
Edit: Y'all are lucky that I moved my dad into my house. He's excellent for refrigeration, AC, and Navy questions.

I don't have a good way to measure air temp but 2 50 cent thermometers have box temp at 10*.
I'll check pressures in the correct places after I get the new cylinder of 404a probably on Wednesday or Thursday depending on who the shipper is.

After a refill and it's running where you want it, it definitely seems like it's running ok. My money is on leak somewhere. Determining where it is might be a bit of a bear. Basically have to check every single joint in the system. U bend joints, flare nuts, valve stems, everything. Takes quite a bit of time sometimes.

I've been arguing with this box for a few years. What's another couple days? It's a damn freezer, I will not let it beat me. My best guess is the low side manifold that is all funky looking.
Funky looking? Spray some soapy water on connectors and see if it fizzes or blows a bubble. It's not very technical but it works.

#9 shows the manifold valve all rusty and funky. It looks like it came from a scrap yard. A new one is on its way.

I bet your dad remembers when the Oriskany had some ordinance get loose and the Enterprise caught it below decks.

I had a brother in law on the Enterprise and a couple buddies on the Oriskany. They all had different stories.
He says they spent more time studying the Forrestal incident rather than the Oriskany. Apparently a guy (who was not a firefighter) tried to extinguish a burning aircraft loaded with ordinance with a 15lb fire extinguisher. No one knows what he was thinking because got blown to smithereens.

I am surprised how thoroughly I have enjoyed this thread. Learning all about freezers, I like it

So far so good. No bubbles where it was possible to test it. The line from the expansion valve to the coils is starting to ice up a little but I can still see copper. It was mentioned about filter screens some where? After the new low side manifold comes in and the weather cools a bit I'll change the manifold, vacuum the system to suck out any moisture and check for leaks. Where would I check for any possible filter screens?
You all have been an unbelievable source of information and I REALLY appreciate all the time that has been taken to help me out with something I know very little about. I'm going to print most of this out for future reference should the need come up. I hope I never need it!
