What is a common consequence of failing to replace a dirty or degraded filter-drier?

The filter-drier protects the system by removing moisture and debris from the refrigerant. When it becomes dirty or degraded, it can’t do that job effectively. Moisture left in the circuit can react with refrigerant and oil to form acids and sludge, which attack metal surfaces and cause corrosion, leaks, and wear. Contaminants and particulate matter can clog narrow passages such as metering devices, capillary tubes, or filters, leading to restricted refrigerant flow and improper lubrication. Together, moisture and contaminants raise the risk of blockages and corrosion, degrading performance and shortening component life.
