What must be done if a freon leak results in the manifold gauge reading 10 psig or lower?

When a freon leak results in the manifold gauge reading 10 psig or lower, it is indicative of a significant loss of refrigerant and could potentially lead to system inefficiencies, compressor damage, or even complete failure if not addressed. In response to this situation, the appropriate action involves replacing the filter drier.

The filter drier plays a crucial role in the refrigeration system by removing moisture, contaminants, and acid from the refrigerant. Low pressure readings often suggest that the system is not operating correctly, and moisture may have entered the system due to the leak. By replacing the filter drier, you can ensure that the system is free of contaminants that might have accumulated during the leak. This action helps restore and maintain the efficiency and longevity of the refrigeration system.

Addressing the issue with the filter drier is essential before refilling the refrigerant and attempting any repairs. Ensuring that refrigerant levels are appropriate and that the system is properly filtered and dried can prevent further complications and facilitate effective repairs afterward.
