How does refrigerant last in a Frigidaire refrigerator?

The refrigerant in a Frigidaire refrigerator is designed to last for the lifetime of the appliance under normal operating conditions. Refrigerant is a closed system within the refrigerator's cooling system, and it is not consumed or depleted with regular use.
However, if your Frigidaire refrigerator is experiencing cooling issues or if you suspect a refrigerant leak, it is recommended to contact a certified technician or Frigidaire customer support for proper diagnosis and repair. Attempting to handle refrigerant-related issues without proper knowledge or training can be dangerous and may void your warranty.
