When frost builds up on the back wall or evaporator coils of your freezer, it can block proper airflow and prevent the appliance from maintaining the correct temperature. In many cases, the compressor will continue running non-stop as it struggles to compensate for the cooling imbalance.
This type of frost accumulation is often linked to a defrost system malfunction, which may involve the defrost heater, defrost thermostat, or defrost timer. These components are designed to regulate temperature and prevent ice buildup — when they fail, frost forms rapidly and cooling performance drops.
Ignoring this issue can lead to higher energy consumption, food spoilage, and additional strain on critical freezer components. Because defrost system problems require electrical testing and component inspection, professional freezer repair is strongly recommended.
