Hey guys, I'm confused. dougrainer and NRALIFER in particular: I presently have a YELLOW JACKET gas pressure test kit model 78060 that I just purchased and haven't used yet and was wondering if the digital units that was mentioned would be a better unit to have than my YELLOW JACKET? The YELLOW JACKET requires different fittings for testing. Does the digital units not? How do they work for reading gas pressures? By the way, I and my two friends with relatively new Dometic refrigerators are having the same problem though not as extreme as the op and the company essentially says that that's the way they are and that these units are "coolers" and not really refrigerators. It sucks big time when you pay $150,000+ for your rv and only get a "cooler".
To test gas pressure you will need to get inside the line, get the pressure to the gauge.
As for the "cooler" idea. The absorption type fridge has been around much longer than a compressor style, and when properly installed can work real good as refrigerators. For a home unit, built and shipped in a self contained cabinet they could be great, except with the same sealing and insulation, they use more power, and in a tight sealed room burning the oxygen might be a issue. The problem in RVs is the RV builder must build the cabinet. And the sloppy workmanship results in bad insulation and worse air flow in many cases. And they got your money, why should they care how well the fridge works?
If you go back to a earlier post this thread you can read a description of what some call a MOD, but I call proper installation to make it cool better.
BTW, Doug and others that work on RVs often should spend the money to buy the tools to check the pressure. I, in the last 20 years, have needed to check propane pressure twice and NG once. My tube and yardstick has worked every time.
We have a liquid tube manometer on the wall we check and adjust our Manomters with. I don't use the digital manometers. Don't see the need. Doug
Similar to this. We are required to calibrate them numerous times a year. It is required by The Texas Railroad Commission and we also have to licensed to service LP and NG in Texas by the TRC
