Warm air entering due to door seal issues

How to Identify: Warm freezer interior, frost only in certain areas, ability to pull paper out easily at door edges

Part: Door gasket/seal

Dirty or obstructed condenser coils

How to Identify: Reduced cooling performance and heat buildup at rear/coils; dust visible on coils

Part: Condenser coils

Faulty evaporator or condenser fan

How to Identify: Unusual noises or no airflow inside freezer; ice buildup on coils

Part: Evaporator/condenser fan motor
