What should the pressure of R134a to recharge refrigerator?
R-134a ideally should have between 25 and 45 psi. Open the refrigerant can port, allowing refrigerant to enter the system. Close the port every minute to check the pressure. Continue to add refrigerant until the pressure has reached the correct range.
Can R134a be used in a freezer?
In short, NO! R 134A is designed for the high demands of an automobile AC and cannot be used on refrigerators due to pressure differences.

What should the operating pressure be for your 134a?
Normal Operating Pressures For R 134a Refrigerant The pressure gauges for this refrigerant stays between 22 PSI and 57 PSI (pounds per square inch). But you have to keep in mind that there are two different sides to this chart. And you have to consider the low as well as the high side.
What should the pressure be on a refrigerant system?
The recommended pressure for a home refrigerator using R134A refrigerant is between 2 psig and 150 psig. Readings that are higher or lower indicate an overcharged system. Although the low side pressure should be around 2 psig, at times it can fluctuate from 0 to -3 psig.
What is the back pressure of a R134a freezer compressor?
Though it depends on you freezer compressor specs. R134a Gas on freezer and cars have different path, so if you want better cooling/freezing use patience in charging it, it will take a few attempts to reach a back pressure of 15–16. How this 19-year-old earns an extra $3600 per week.
Is the R-134a refrigerant still used in cars?
That being said, there are still millions of cars on the road that use R-134a and there will be continue to be for at least another decade or more. When something does go wrong with your car’s air conditioner a lot of folks are not sure what to do or where to even start.
