 I had a Pepsi machine here that I was here two and a half months ago and I fixed a leak on the suction line and I put an E-filter dryer, one of those capped heat dryers on there. I got here just pulling into a negative when I grabbed my gauge set, which is not my favorite one because my 557s took a dump and tested once outrageous money to fix them. So I'm using these, went ahead and turned it on with these connected and what I found was it looks like from the pressure I'm seeing on my high side and I have restriction. So that's what I thought would do real quick just to show you what it looks like. If you watch the head pressure here I figure it's maybe 70 in here so 80, 90, 100, 100 degree sciaturation temperature would be 30, they got up to 170 something earlier. Generally, you know, here we are into a negative. When you feel it, it feels cold because it's getting starved but basically it's pumping up against that capillary tube that's restricted and I used nitrogen when I did it but just to be certain this thing holds 12 ounces so we got it zeroed out, we're going to add a little bit to it. This is our 134A so we can do it in vapor, go ahead and get this thing in here. I bled all my hoses out beforehand and see where our head pressure is going, just two ounces. So it's just two ounces of refrigerant, still pulling down into a negative with that kind of head pressure that's not low on refrigerant. So in that case there what we'll do is we'll order a new capillary tube because right up the inside wall comes into the back of the evaporator coil there. We'll probably have to run it on the outside of the cooler just because you can't get to the inside but yeah, that's when you watch what your head pressure's doing, it's starting to drop down. It builds head pressure up because it's pulling up against that and then there she goes again. So that is a restriction on a capillary tube, all proper procedures are done but that compressor ran after it had leaked before I got here, it ran, baked that oil, that oil a lot of times will break down and then it'll get looked around in the system and it gets caught in the capillary tubes. So I would say it was probably already in there and it just broke loose afterwards. It ran from us two and a half months but that's what's going on and in case you were wondering was it a problem with the dryer or not, no it's not. Went ahead and blew through it, you can hear it just fine and right here's the biggest thing I hate about these stupid gauges, they don't reset back to zero, the 557s did but they were made in Germany, 99.9% sure these things are made in China for the price they sell them for but if you're not selling a quality unit what's it really matter.
