Advertisements
AL
Display shows AL and an audible alarm sounds; temperature may be high or door may be open.
General Alarm Condition (Door or Temperature)
dF
Display shows dF or DEF; freezer may pause cooling during this time.
Defrost Mode Indication (Not a Fault)
E1
Freezer beeps and displays E1; temperature rises above set point and compressor may not start or runs briefly then stops.
Freezer Compartment Sensor (Thermistor) Failure
E10
Freezer displays E10 and may not maintain set temperature; compressor may short-cycle.
Main Control PCB Temperature Regulation Fault
E2
Freezer displays E2 and may run continuously or shut down cooling intermittently; temperature control seems inaccurate.
Ambient / Cabinet Temperature Sensor Failure
E3
Freezer shows E3 and may not defrost properly; heavy frost builds up on the evaporator and airflow is reduced.
Defrost Sensor / Evaporator Thermistor Failure
E4
Freezer displays E4 and may stop cooling or run continuously; compressor operation is erratic.
Compressor Discharge / Condenser Sensor Failure
E5
Freezer shows E5 and may not defrost; ice accumulates on evaporator and fan noise may increase.
Defrost Heater Circuit Failure
E6
Freezer displays E6 and may not respond correctly to keypad or touch controls; temperature settings may not change.
User Interface / Control Panel Communication Error
E7
Freezer shows E7 and the internal fan may not run; cooling is weak and uneven.
Evaporator Fan Motor Feedback / Circuit Error
E8
Freezer displays E8 and may not start the compressor; unit may click repeatedly or remain off.
Compressor Start / Overload Protection Error
E9
Freezer shows E9 and interior light or fan may behave erratically; door alarm may not function correctly.
Door Switch / Door Sensor Error
F1
Freezer shows F1 and may not maintain correct temperature; control may revert to default settings.
Internal Control Memory / EEPROM Error
F2
Freezer shows F2 and may not respond to temperature adjustments; display may freeze or reset.
Control Panel Keypad / Touch Error
H1
Display shows H1 or HI and an alarm sounds; internal temperature is too high and food may be soft or thawing.
High Temperature Alarm Condition
L1
Display shows L1 or LO; interior temperature is excessively low and items may be over-frozen or ice crystals form on packaging.
Low Temperature / Overcooling Fault
Symptom
Buttons on the control panel do not respond or respond intermittently.
Keypad / Touch Control Failure
Symptom
Digital display is blank or flickering, but the freezer still cools.
Display / User Interface Power Issue
Symptom
Excessive frost buildup on food packages and interior walls, especially near the door.
Excessive Frost – Air Infiltration
Symptom
Freezer alarm sounds intermittently even though temperature appears normal.
Nuisance Alarm – Sensor or Door Switch Issue
Symptom
Freezer door difficult to open immediately after closing; suction effect and popping sound.
Normal Vacuum / Pressure Equalization
Symptom
Freezer door does not close or seal properly; door pops open or remains slightly ajar.
Door Alignment / Hinge or Gasket Problem
Symptom
Freezer emits a high-pitched squealing or chirping noise, especially when the door is closed.
Evaporator Fan Bearing Wear
Symptom
Freezer emits a strong chemical, burning, or plastic smell during operation.
Odor from Electrical or Insulation Components
Symptom
Freezer has a strong, unpleasant food or mold odor inside.
Internal Odor Contamination
Symptom
Freezer has heavy frost or ice buildup on the back wall or around the evaporator cover.
Defrost System Failure
Symptom
Freezer interior is warm but compressor and condenser fan are hot and running continuously.
Sealed System Underperformance (Low Charge or Restriction)
Symptom
Freezer interior light does not work, but cooling is normal.
Interior Light Circuit Failure
Symptom
Freezer interior light works but compressor and fan do not run; no humming or clicking sounds.
No Cooling – Control or Thermostat Not Calling for Cooling
Symptom
Freezer is noisy; loud humming, buzzing, or rattling sounds during operation.
Excessive Operational Noise
Symptom
Freezer is too cold; items are rock hard and ice forms heavily on packages even at moderate settings.
Overcooling – Thermostat or Sensor Miscontrol
Symptom
Freezer makes a loud banging or knocking noise when the compressor starts or stops.
Compressor or Tubing Knock
Symptom
Freezer not cooling at all; interior is at room temperature, compressor not running, display may be on.
No Cooling – Compressor Not Running
Symptom
Freezer runs but does not get cold enough; temperature is higher than set point and food is soft.
Poor Cooling – Long Run Time
Symptom
Freezer runs continuously without shutting off; temperature may be normal or slightly low.
Continuous Running – Control or Air Leak Issue
Symptom
Freezer trips the household circuit breaker or blows fuses when it starts.
Electrical Short or Overcurrent
Symptom
Freezer vibrates excessively or rattles against the floor or surrounding cabinets.
Cabinet Vibration / Installation Issue
Symptom
Water or ice buildup on the freezer floor inside the compartment.
Internal Water Leak – Frozen or Blocked Defrost Drain
Symptom
Water pooling on the floor under or around the freezer.
External Water Leak / Drainage Issue
