- The “normal” pressure can vary depending on your fridge model and the refrigerant used. Generally, the low-side pressure should be around 0 PSI at rest, and the high-side pressure could be around 120 PSI when the fridge is running. You can usually find the specific values in your fridge’s manual or on the manufacturer’s website.
