What is the correct low side pressure for a mini fridge? VestFrost red bull. Doesn't seem to turn on until I give it 30psi while running

Wouldn't cool. Connected the gauges and says -10hg pressure while the compressor tried to run. So super low. I added freon, now trying to optimize because I think I added too much. Here's the sticker on the back of the fridge. https://preview.redd.it/bfuar3ac6zh51.jpg?width=1462&format=pjpg&auto=webp&s=0bef67f1354a46c690ae8299ce58e0275b9d5bd4 I stupidly thought that "design pressure low side 88 psig" meant to fill it to 88 psi. (Is this the factory tested pressure? I have no idea what the pressure should be in this line without the compressor running) BUT I know it says .052kg of coolant, aka 52grams, aka 1.83oz. So I pulled a vacuum for an hour, let it hold for another hour, (It wouldn't pull more than 25 bc this line they gave me is fucky, but it held) weighed the coolant can, and pumped in 18grams while connected to the service line. It started cooling. Then my dumb brain thought, well that's no where near 88psi, so I let it slurp in another 20 grams of coolant for a total of 38 grams. Current stats at idle the pressure is 65psi. compressor running pressure is 25psi Fridge temp is 40 compressor temp is 37 High side line temp is 80 These seem to be OK numbers except for the ridiculous high low-side pressure, meaning I've overfilled it, right? Do I need to release low side pressure until it reads about 5psi / 0* on the scale for r134a? submitted by /u/FjordTV [link] [comments]
