Common Reasons for Freezer Issues While the Refrigerator Works Several things can cause a freezer to stop working right, even if the fridge part is okay. One reason might be a broken thermostat or temperature sensor that’s meant for the freezer. These parts help control how cold the freezer is, and if they don’t work, the cooling can fail. Other reasons could be problems with the evaporator fan motor or blocked airflow caused by frost on the evaporator coils. The door seal might also be faulty, which could let warm air into the freezer. Plus, if the defrost system is not working properly, it can lead to too much ice on the evaporator coils. This ice buildup makes it hard for air to flow and can reduce how well the freezer cools. Preparing to Troubleshoot Your Sub Zero Freezer Before you start troubleshooting, safety is very important.
