E1
Digital display shows E1 and cabinet is not cooling or cooling poorly.
Cabinet Temperature Sensor (Thermistor) Failure
E2
Display shows E2 and temperature readings are erratic or the unit overcools/undercools.
Ambient / Upper Zone Temperature Sensor Failure
E3
Display shows E3 and lower zone does not maintain set temperature (dual-zone models).
Lower Zone Temperature Sensor Failure
E4
Display shows E4 and compressor or fan operation is erratic; unit may shut down unexpectedly.
Evaporator Defrost Sensor or Evaporator Sensor Fault
E5
Display shows E5 and compressor does not start or cycles rapidly; temperature cannot be maintained.
Compressor Overload or Start Protection Fault
E6
Display shows E6 and the interior fan does not run or runs intermittently; temperature is uneven.
Evaporator Fan Motor Fault
E7
Display shows E7 and the unit may not respond correctly to temperature settings; display may flicker.
Control Panel / Touchpad Communication Error
E8
Display shows E8 and the interior light or display backlight may not function correctly.
LED Lighting Circuit Fault
E9
Display shows E9 and the unit may shut down or fail to start; sometimes accompanied by beeping.
Main Control Board Fault / EEPROM Error
H1
Display shows H1 or flashes a high temperature warning; interior is warm.
High Temperature Alarm Condition
L1
Display shows L1 or low temperature warning; bottles may be too cold or partially frozen.
Low Temperature Alarm Condition
Symptom
Beeping alarm with door closed; door-ajar alarm sounds even when door is shut.
Door Switch or Magnet Misalignment
Symptom
Clicking sound from the back; compressor tries to start but shuts off repeatedly.
Compressor Start Failure
Symptom
Condensation forming on the exterior glass door.
High Humidity / Door Insulation Issue
Symptom
Control buttons unresponsive or respond intermittently.
User Interface / Touchpad Failure
Symptom
Display is blank or very dim, but interior light and cooling still work.
Display Module or Backlight Failure
Symptom
Display temperature does not match actual interior temperature.
Temperature Calibration or Sensor Drift
Symptom
Door not sealing properly; warm air enters and condensation forms around the door.
Door Gasket or Hinge Misalignment
Symptom
Excessive frost or ice buildup on the back wall or evaporator cover inside the wine cooler.
Defrost / Drainage Problem or Air Infiltration
Symptom
Interior fan runs but compressor does not, and the unit slowly warms up.
Compressor Circuit Failure
Symptom
Interior light stays on all the time or never turns on when the door is opened.
Door Switch or Light Circuit Failure
Symptom
Interior surfaces feel unusually hot or warm to the touch near the door frame.
Door Frame Heater Operation or Heat Transfer
Symptom
Interior temperature fluctuates widely; some bottles too warm, others too cold.
Airflow Imbalance or Sensor Placement Issue
Symptom
Loud humming, buzzing, or rattling noise during operation.
Vibration or Fan Noise Issue
Symptom
Shelves difficult to slide in and out; may scrape against interior walls.
Rack Alignment / Cabinet Deformation
Symptom
Strong chemical or burning smell coming from the back of the unit.
Overheating Electrical Component
Symptom
Unit cools initially but then stops cooling until power is cycled.
Control Board Lockup or Overheat Protection
Symptom
Unit cycles on and off very frequently (short cycling).
Improper Thermostat Control or Oversensitive Sensor
Symptom
Unit makes a gurgling or hissing sound periodically.
Normal Refrigerant Flow Noise
Symptom
Unit trips the household circuit breaker when plugged in or when compressor starts.
Electrical Short or Overcurrent
Symptom
Unit vibrates excessively and may move or rattle against cabinets.
Cabinet Vibration / Leveling Issue
Symptom
Water pooling at the bottom of the wine cooler or leaking onto the floor.
Condensate Drain Blockage or Excess Condensation
Symptom
Wine cooler has power (lights/display on) but compressor and fan never start.
Control Board Not Activating Compressor Circuit
Symptom
Wine cooler not turning on at all; no lights, no display, no sound.
No Power / Power Supply Failure
Symptom
Wine cooler runs but does not cool; interior stays at room temperature.
Compressor or Sealed System Failure
