Viking Refrigerator Defrost System Fault
A defrost system fault in a Viking refrigerator occurs when the automatic defrost cycle fails, allowing ice to build up on the evaporator coil and block airflow to the refrigerator compartment. The freezer stays cold because it is in direct contact with the iced-over coil, while the refrigerator section gradually warms. Defrost system failure is one of the most common Viking refrigerator faults.
What Causes the Defrost Fault Error?
The heater element that melts frost from the evaporator coil during each defrost cycle has burned out.
The bimetallic thermostat that controls heater power has failed open, preventing the heater from receiving power.
The adaptive defrost control or timer has failed, preventing defrost cycles from occurring.

When to Call a Technician
