A question about PSI for Kitchenaid fridge KFCS22EVMS

[Nola]

My old fridge KTRA22EMSS shows the 'design pressure' as 140 PSI low and 330 PSI high. My new fridge (see title) doesn't show PSI period. Is there a way to find out?

My fridge guy tried to do a reading and the high was 105, the service line was damaged on the low so he could not get a reading. He did IR temp on the condenser (65) and on the suction line (67). I'm thinking these are bad#'s but would like to have something to compare to....

Thx

So what do you do for a living Nola with 19 posts to your credit?

Those numbers relate to system design pressures - not working pressures

Thank you Frank. Can you give me an idea of what working pressures would look like. Much appreciated!

You don't say what the refrigerant is
