Advertisements
E0
Display shows E0 and the wine cooler does not cool or responds erratically to temperature changes.
Temperature Sensor (NTC) Communication Fault
E1
E1 error on display and the wine cooler runs continuously or does not maintain the set temperature in the upper zone.
Upper Zone Temperature Sensor Failure
E2
E2 error code displayed and the lower zone temperature is inaccurate or not cooling correctly.
Lower Zone Temperature Sensor Failure
E3
E3 error on the display and the internal fan in the cabinet does not run or runs intermittently.
Evaporator / Circulation Fan Motor Fault
E4
E4 error code and the compressor does not start or cycles off quickly; cooling performance is poor.
Compressor Start / Overload Protection Fault
E5
E5 error displayed and the wine cooler interior is too warm even though the compressor seems to run for long periods.
High Temperature / Cooling System Fault
E6
E6 error code and the display or control panel behaves erratically, with buttons not responding correctly.
Control Panel / Main PCB Communication Error
E7
E7 error on display and the interior light or other low-voltage accessories do not function correctly.
Low-Voltage Power Supply / Accessory Circuit Fault
E8
E8 error code and the wine cooler shows large temperature swings or cannot reach the setpoint despite running.
Defrost / Evaporator Sensor or Heater Fault
E9
E9 error displayed and the wine cooler may shut down or operate erratically after a power event.
EEPROM / Memory Data Error
H1
H1 or HI displayed and the cabinet temperature is significantly higher than the setpoint.
High Temperature Alarm Condition
L1
L1 or LO displayed and the cabinet temperature is much lower than the setpoint; bottles may feel too cold.
Low Temperature Alarm Condition
Symptom
Alarm beeps periodically even though the temperature appears normal and the door is closed.
False Alarm / Door or Temperature Sensor Misread
Symptom
Burning smell or signs of overheating near the back or control panel.
Electrical Overheating / Component Failure
Symptom
Cabinet interior is too cold in spots and too warm in others; uneven temperature distribution.
Poor Air Circulation Inside Cabinet
Symptom
Cabinet temperature is much warmer than setpoint even though the compressor and fans run; condenser is extremely hot.
Overheating Condenser / Poor Ventilation
Symptom
Compressor never starts; only fans or lights operate, and the cabinet warms up.
Compressor Not Starting
Symptom
Display is dim, flickering, or some segments are missing, but cooling is normal.
Display Backlight / Segment Failure
Symptom
Display is on but buttons do not respond or respond intermittently.
Unresponsive Touch Control Panel
Symptom
Door does not close properly or pops open slightly after being shut.
Door Alignment / Hinge or Gasket Problem
Symptom
Dual-zone Aobosi wine cooler: one zone cools properly while the other is too warm or too cold.
Single-Zone Cooling Imbalance
Symptom
Excessive frost or ice buildup on the back wall or around the evaporator inside the cabinet.
Frost Accumulation / Defrost Failure
Symptom
Glass door is fogged or has condensation between the panes of glass.
Failed Door Seal / Insulated Glass Unit Leak
Symptom
Gurgling or sloshing sounds from inside the cabinet or back of the unit.
Normal Refrigerant Flow Noise / Drain Water Movement
Symptom
High-pitched whine or buzzing noise from the back of the wine cooler.
Noisy Condenser Fan or Electrical Buzz
Symptom
Interior light does not turn on when the door is opened, but the cooler otherwise works normally.
Interior Light Failure
Symptom
Interior surfaces and bottles feel damp; condensation forms on the glass door.
Excessive Condensation
Symptom
Shelves are difficult to slide in and out or scrape against the cabinet walls.
Shelf Rail Misalignment / Deformation
Symptom
Strong plastic or chemical odor inside the wine cooler that persists after initial use.
Persistent Odor / Contamination
Symptom
Thermoelectric (Peltier) Aobosi wine cooler: unit powers on but interior remains warm; only a faint hum is heard.
Peltier Module / Thermoelectric Cooling Failure
Symptom
Thermoelectric Aobosi wine cooler: one of the fans is noisy or not spinning, and cooling is weak.
Thermoelectric Fan Failure
Symptom
Water pooling at the bottom of the cabinet or leaking onto the floor in front of the wine cooler.
Condensate Drain Blockage or Door Gasket Leak
Symptom
Wine cooler cools but temperature is unstable, with frequent swings of several degrees.
Inaccurate Temperature Control / Sensor Drift
Symptom
Wine cooler does not power on at all; display is blank and no lights or fans run.
No Power / Input Power Failure
Symptom
Wine cooler is running constantly and never seems to shut off, though it may still reach temperature.
Continuous Run / Short Cycling Control
Symptom
Wine cooler makes loud rattling or vibrating noises during operation.
Excessive Vibration / Mechanical Noise
Symptom
Wine cooler runs (fans and compressor audible) but does not cool; interior remains at room temperature.
Loss of Refrigerant / Sealed System Failure
Symptom
Wine cooler trips the household circuit breaker or GFCI outlet when it starts.
