Blomberg fridge compressor was shot, replaced and charged with 600a to roughly 1.7oz as per specs. Was running fine in the beginning but now freezer is working fine but fridge temps are high! Fan is running in both, defrost working fine and no access to fridge evaporator as its foamed in. Suction side showing -15in hg while running, understand characteristics of 600 is different but certain suction should be in + side - tried adding more refg brought down suction from -22 to -15in hg but now looks system is overcharged. any input??
I doubt you have the specialized equipment needs to do this successfully. I wrote this for vehicle AC, but just change the word 'AC' to 'Fridge'. The procedure is the same. You can't eyeball this stuff. Also, with the new compressor, did you add oil and a new dryer?
