AL
Proline freezer shows AL or an alarm icon with beeping, often after a power cut or door left open.
General Alarm Condition (Temperature or Door)
dF
Proline freezer briefly shows dF on the display and may beep; unit pauses cooling during this time.
Automatic Defrost Mode Indication
E1
Digital Proline upright freezer displays E1 and stops cooling or runs continuously without reaching set temperature.
Cabinet Temperature Sensor (NTC) Failure
E2
Proline freezer shows E2 and may over-freeze or fail to maintain stable temperature.
Evaporator Temperature Sensor (NTC) Failure
E3
Proline freezer displays E3 and may not respond correctly to temperature setting changes.
Ambient / Room Temperature Sensor Failure
E4
Proline freezer shows E4 and may not defrost properly, leading to ice buildup on the evaporator.
Defrost Sensor / Defrost Thermostat Fault
E5
Proline freezer displays E5 and may not defrost; heater does not warm during defrost cycle.
Defrost Heater Circuit Fault
E6
Proline freezer shows E6 and the compressor may not start or may run erratically.
Compressor Start / Inverter Communication Fault
E7
Proline freezer displays E7 and the internal fan may not run, causing uneven cooling and ice buildup.
Evaporator Fan Motor Fault
E8
Proline freezer shows E8 and the display or control panel may be unresponsive or flickering.
Display PCB / User Interface Communication Fault
E9
Proline freezer displays E9 and may not cool; compressor does not run even though lights and display are on.
Main Control PCB Fault
H1
Proline freezer shows H1 or HI and an alarm sounds; internal temperature is too high.
High Temperature Alarm Condition
L1
Proline freezer shows L1 or LO and may indicate abnormally low temperature inside the cabinet.
Low Temperature Alarm / Overcooling Condition
Symptom
Alarm beeps intermittently even though the temperature appears normal and the door is closed.
False Alarm Due to Door Switch or Sensor Error
Symptom
Chest freezer interior walls are heavily iced; manual defrost is required very frequently.
Excessive Moisture Ingress
Symptom
Chest freezer lid will not stay open or slams shut unexpectedly.
Lid Hinge or Support Failure
Symptom
Condensation or sweating on the exterior cabinet walls or around the door seal.
Surface Condensation Due to Humidity
Symptom
Digital display is blank or very dim, but the freezer still cools.
Display Power or Backlight Failure
Symptom
Freezer door difficult to open immediately after closing; a vacuum seems to hold it shut.
Normal Pressure Equalization / Door Vacuum
Symptom
Freezer emits a strong chemical or burning smell during operation.
Overheating Electrical Component or Contaminant on Heater
Symptom
Freezer interior fan runs loudly or at high speed but the cabinet is still warm.
Air Circulation Without Effective Cooling
Symptom
Freezer interior is too warm; compressor cycles on and off but temperature remains above -10°C.
Thermostat / Temperature Control Miscalibration
Symptom
Freezer interior temperature fluctuates widely; some days too warm, other days too cold.
Inconsistent Temperature Control
Symptom
Freezer is noisy; loud humming, buzzing, or rattling sounds during operation.
Mechanical Vibration or Fan Noise
Symptom
Freezer is too cold; items near the back are rock solid and some items may crack or split.
Overcooling Due to Stuck Thermostat or Sensor Fault
Symptom
Freezer is vibrating excessively and may move or rattle against surrounding cabinets.
Cabinet Vibration / Installation Issue
Symptom
Freezer makes a loud knocking or banging noise when the compressor starts or stops.
Compressor Mounting or Internal Mechanical Noise
Symptom
Freezer not cooling at all; interior light works but temperature remains warm and food is thawing.
Compressor Not Running
Symptom
Freezer runs continuously but does not reach the set temperature; back wall may show only partial frost pattern.
Refrigerant Undercharge or Partial Blockage
Symptom
Freezer trips the household circuit breaker or RCD when plugged in or shortly after starting.
Electrical Short or Earth Leakage
Symptom
Freezer will not start at all; no lights, no display, and no sound.
No Power / Supply Issue
Symptom
Frost or ice buildup on the interior walls, especially near the door opening.
Air Ingress Due to Door Seal Problem
Symptom
Heavy frost and ice buildup on the evaporator behind the rear panel; airflow is restricted and cooling performance drops.
Defrost System Failure
Symptom
Interior light does not work when the door is opened, but the freezer cools normally.
Door Switch or Light Circuit Failure
Symptom
Plastic interior liners or baskets have cracked; sharp edges may be present.
Physical Damage to Interior Components
Symptom
Water pooling under or inside the freezer; ice may form on the bottom of the compartment.
