The freezer compartment is not working properly due to a recurring issue of ice buildup. This problem returns even after a service person has manually thawed the ice, suggesting an underlying system fault.

• Defective defrost heater or thermostat
• Faulty defrost sensor (thermistor)
• Poor freezer door seal allowing warm, moist air entry
