E2
Freezer shows E2 and struggles to maintain temperature; compressor may run continuously.
Ambient / Cabinet Temperature Sensor Fault
E20
Freezer shows E20 and may emit a continuous alarm tone; temperature may be too high.
High Temperature Alarm / Prolonged Warm Condition
E21
Freezer displays E21 and the interior light or fan may not turn off when the door is closed.
Door Status Signal Stuck / Logic Error
E22
Freezer shows E22 and may not maintain set temperature; compressor cycles may be abnormal.
Control Board Internal Error
E23

Defrost Control / Sensor Correlation Error
E25
Freezer displays E25 and the internal fan speed seems abnormal (too slow or not running steadily).
Fan Speed / Feedback Error
E3
Display shows E3, freezer temperature fluctuates, defrost cycles seem irregular (too much ice or frequent defrost).
Evaporator Temperature Sensor Fault
E4
Freezer displays E4 and may not defrost properly; ice builds up on the evaporator and airflow is reduced.
Defrost Heater or Defrost Circuit Failure
E5
Freezer shows E5, compressor may not start or may stop shortly after starting.
Compressor Start/Run Circuit Fault
E6
Freezer displays E6 and interior fan may not run, leading to uneven temperatures and warm spots.
Evaporator Fan Motor Fault
E7
Freezer shows E7 and may not respond correctly to temperature setting changes; display may show incorrect temperatures.
User Interface / Control Panel Communication Error
E8
Freezer displays E8 and may show unusually high or low temperature readings not matching actual conditions.
Temperature Calibration / Sensor Range Error
E9
Freezer shows E9 and may not cool; compressor may not run or may shut down quickly.
High Temperature / Overheat Protection Error
Symptom
Alarm beeps frequently even though the door is closed and temperature seems normal.
False Alarm / Alarm Circuit Fault
Symptom
Excessive frost buildup on the interior walls, shelves, and food packages.
Excessive Frost / Moisture Ingress
Symptom
Freezer display works but compressor and fan never start; interior remains warm.
Control Output Failure / No Cooling Command
Symptom
Freezer does not start at all; display is blank and no lights are on.
No Power / Dead Appliance
Symptom
Freezer door does not close properly or pops open slightly after closing.
Door Alignment / Hinge or Gasket Problem
Symptom
Freezer door handle feels loose or wobbly, making it hard to open or close the door firmly.
Loose Door Handle / Hardware Wear
Symptom
Freezer fan runs loudly and continuously even when the compressor is off.

Symptom
Freezer forms a thick sheet of ice on the bottom, sometimes leaking water onto the floor.
Blocked Defrost Drain
Symptom
Freezer interior has a strong, unpleasant odor even after removing spoiled food.
Persistent Odor / Contamination
Symptom
Freezer interior light not working, but cooling is normal.
Interior Lighting Failure
Symptom
Freezer interior light stays on even when the door is closed, causing warming near the lamp area.
Light Stuck On / Door Detection Failure
Symptom
Freezer interior too cold, excessive frost on food, and temperature lower than setpoint.
Overcooling / Thermostat or Sensor Misregulation
Symptom
Freezer is noisy, with loud humming, rattling, or knocking sounds during operation.
Excessive Operational Noise
Symptom
Freezer makes a loud buzzing or clicking noise and then stops; compressor does not stay running.
Compressor Start Failure
Symptom
Freezer not cooling at all, interior is warm, display may appear normal but temperature does not drop.
Complete Loss of Cooling
Symptom
Freezer runs constantly and never reaches the set temperature; compressor is hot and food is soft.
Insufficient Cooling / Partial Loss of Refrigerant
Symptom
Freezer shelves or drawers difficult to slide, with ice forming around runners and rails.
Drawer / Shelf Icing
Symptom
Freezer temperature fluctuates widely, sometimes freezing too hard and other times too warm.
Unstable Temperature Control
Symptom
Freezer vibrates excessively and can be felt or heard through adjacent cabinets or floor.
Excessive Vibration
Symptom
Water leaking from under the freezer onto the floor.
