A/C R134a pressures too high. I'm lost. Ideas?
Hey guys,
Replaced my Receiver/Drier today while I decided to evacuate and recharge because I believed I had air in the lines because high side pressures were almost hitting 400psi!! So I replaced the R/D, resealed everything, evacuated for 45mins held at 26 inHg, turned compressor off for 10mins and came back to find everything dead on where I left it... So no leaks. (no leaks prior either) r134a needs 900mg for W124 = ~32oz. I put 1 + 1/2 12oz cans in so ~20oz (it wouldn't take the 2nd can full at all even after 20mins 2000rpm and putting the can in hot water) Ambient Temperature: 104F After this my pressures are: Low: 59psi High: 360psi Aux fans are on full blast. I ended up re-evacuating AGAIN to make sure I didn't make a mistake with air getting in and same issue. Why are my pressures SO high? Somethings wrong. ![]()
