Sub-Zero Fridge Not Cooling? Evaporator Kit 7002257 – Fix Icing, Warm Compartments & Cooling Failure
If your Sub-Zero refrigerator is not maintaining temperature, the evaporator coils are icing over completely, or the fridge compartment is warm while the freezer runs — a failed or degraded evaporator assembly is the most likely cause. In Sub-Zero refrigerators, the evaporator kit includes the evaporator coil and associated components that form the core of the sealed cooling system inside the cabinet. When the evaporator fails or becomes blocked with ice, airflow to the refrigerator compartment is cut off entirely — causing the fridge section to warm while the compressor continues to run. ⚡ This part (7002257) has been discontinued by Sub-Zero. If you need this evaporator kit, contact us — we may be able to source a compatible alternative. Part 7002257 was the OEM evaporator kit that restored proper refrigerant flow, defrost cycling, and full cooling performance to compatible Sub-Zero refrigerators.
❓ Is This the Right Part?
This was the correct fix if ALL of the following were true:
- ✔ Refrigerator powers on — compressor, fans, and controls are operational
- ✔ Freezer section may be cold but fridge compartment is warm
- ✔ Evaporator coils are heavily iced over or evaporator is physically damaged/corroded
- ✔ Defrost system has been confirmed functional (heater and thermostat tested OK)

💡 Pro Tip
Before sourcing an evaporator kit, unplug the Sub-Zero for 24–48 hours with the doors open to allow a complete manual defrost. If cooling returns to normal afterward, the evaporator coil itself may be intact — the problem could be a failed defrost heater or thermostat, which are still available. If cooling fails again within days, the evaporator replacement is warranted — contact us for sourcing help.
