Yes sir are you talking about the accumulator it's brand new... It didn't say any more sure of any kind yesterday like I say I purge each piece separately... Each line each tube the condenser and the evaporator. Make sure that every drop of the moisture was blue out of every line. The accumulator with the last thing I installed when I reinstalled everything. Of course like I said the compressor was blocked off with the shipping block that came with it it did not see any moisture at all either.

 

Well, looks like I'm gonna have to get a CERTIFIED TECHNICIAN... I don't trust the last garage and my mobile tech is pretty much just going to skip out on me... So that being said I have a few questions....

​​​​Is the orifice a necessary item for the system?
Could the orifice malfunction under pressure, to where it would not malfunction otherwise?
I think I have determined that the orifice is not unidirectional because air and fluid flows both ways at pressures 100 lb and less. I just did not know if under extreme pressure if it made malfunction. And I think that's about it,

 

Two things I'm noticing here. 1, yes the orifice tube is the heart of what makes the system blow cold, and 2, ya might wanna replace the shrader valve on the low press side. If you're correct and all of the water you forced thru the system is gone via vacuum pumping the system for a very long time (~1 hour or more), then the only thing that could block the refrigerant from going in is maybe the shrader valve on the low side. Assuming you're adding the refrig thru that low side valve?

 

Yessir I'm NOT adding any refrigerant..supposedly trained techs are doing that. I'm unfamiliar with the valve you mentioned. It is located where? And the tubes, hoses, condenser were blown out with high pressure (100lbs), left in the Texas Sun, and blew out again. The evaporator was blown out several times throughout the day. I'm confident that only condensation is the ONLY liquid that MAY be left in the system. Like I said the entire system was disassembled and cleaned one piece at a time. Of course the brand new compressor had the shipping block reinstalled while cleaning the remaining parts and the new accumulator was the last thing installed. The valve you mentioned I am unfamiliar with.

 

Its like a tire valve stem core, and is replaced the same way. Should be on the low pressure side of the circuit, so, the line running from the condenser, to the accumulator. Sometimes, it is actually ON the accumulator.

 

YES...it is on the accumulator...there is a "switch" that screws on it with a plug in. And the accumulator is new.

 

Nope, low pressure port will be very similar, but, nothing screwed to it, aside from maybe a cap.

 

Okay I understand what you're talking about I understand now yeah that's where he hooks his one of his hoses is the AC guy he hooks one of his hoses there and the other one to the side of the lines block going on the compressor... That is the tube that the orifice is in on this 94. Anyway I got you I completely understand what you're talking about now. Again can't thank you enough for all your information and response.

 

Okay after everything we did the mobile technician come back out and try to charge it it did the same thing. We jumped they relay and the compressor started however it only took about a half a can in stopped. He called his boss man or top level technician anyway he was having a hard time believing that the new compressor the new denso brand compressor was bad so he said first change both the pressure switches on the compressor tube and the accumulator. After that everything on the entire system will be new not rebuilt but new. Except for the evaporator and it blew through perfectly clean and the fan motor blows like a shop fan through it.

 

is it possible to test an ac compressor as a stand alone unit without having the system hooked to it?
