AL18
Freezer displays AL18; the unit may run, but the interior temperature reading is clearly incorrect.
Display Temperature Calibration / Sensor Mapping Error
Symptom
Alarm beeping without any visible error code; temperature appears normal.
False Alarm / Alarm Circuit Fault
Symptom
Bad odor inside freezer even after removing spoiled food.
Persistent Odor Contamination
Symptom
Condensation or sweating on exterior cabinet walls or around door frame.
Condensation / Insulation or Heater Issue
Symptom
Freezer door difficult to open immediately after closing; strong suction effect.
Normal Vacuum / Venting Issue
Symptom
Freezer door not closing properly; door pops open or remains ajar.
Door Alignment / Hinge Wear
Symptom
Freezer interior light flickers or is dim.
Lighting Power or LED Degradation
Symptom
Freezer interior surfaces feel hot to the touch near the door frame.
Door Frame Heater Overheating
Symptom
Freezer interior too cold; items are excessively hard or ice crystals are everywhere, even at a low setting.
Overcooling / Thermostat Stuck Closed
Symptom
Freezer makes loud knocking, rattling, or banging noises during operation.
Mechanical Vibration / Loose Components
Symptom
Freezer not cooling at all; interior is at room temperature, light works but no cold air.
Complete Loss of Cooling
Symptom
Freezer not starting at all; no lights, no display, completely dead.
No Power / Dead Appliance
Symptom
Freezer runs continuously and never cycles off; temperature may be too warm or too cold.
Thermostat or Temperature Control Failure
Symptom
Freezer runs noisily only during defrost or shortly after.
Defrost Expansion / Drip Noise
Symptom
Freezer temperature fluctuates widely; sometimes too warm, sometimes too cold.
Unstable Temperature Control
Symptom
Freezer too warm; food is softening, but the compressor and fan seem to run.
Insufficient Cooling / Partial Loss of Capacity
Symptom
Freezer trips the circuit breaker or RCD when plugged in or when the compressor starts.
Electrical Short / Earth Leakage
Symptom
Freezer vibrates excessively or hums loudly, especially when the compressor starts.
Excessive Vibration / Poor Installation
Symptom
Frost or ice buildup on the interior walls, ceiling, or around the door opening.
Air Infiltration / Gasket Leak
Symptom
Heavy ice buildup on evaporator coil; airflow reduced, temperature rising.
Defrost System Failure
Symptom
High-pitched squealing or chirping noise from inside the freezer.
Evaporator Fan Bearing Wear
Symptom
Interior light not working but freezer otherwise cools normally.
Lighting Circuit Failure
Symptom
Water pooling at the bottom of the freezer or on the floor in front.
Defrost Drain Blockage
