The ideal pressure for the compressor in a refrigerator depends on the specific make and model of the refrigerator you have. Different refrigerators may have different requirements based on their design, cooling capacity, and refrigerant used. It's crucial to consult the manufacturer's guidelines or the refrigerator's user manual for the correct pressure specifications.
Attempting to adjust the compressor pressure without proper knowledge and tools can be dangerous and may lead to damage or malfunction of the refrigerator. Refrigeration systems are complex, and their components should only be handled by trained professionals with the right equipment and knowledge.
If you suspect that there is an issue with your refrigerator's compressor, it's best to contact a certified technician or a professional appliance repair service to diagnose and fix the problem. They have the expertise to handle refrigeration systems safely and effectively.
