E0
Display shows E0 and the wine cooler does not cool properly or at all.
Cabinet Temperature Sensor (NTC) Failure
E1
Display shows E1 and the wine cooler runs erratically or does not maintain set temperature.
Evaporator Temperature Sensor (NTC) Failure
E2
Display shows E2 and the wine cooler may overcool or not cool correctly.
Ambient / Room Temperature Sensor Failure
E3
Display shows E3 and the compressor or fan may not run correctly; unit may shut down prematurely.

E4
Display shows E4 and the wine cooler may not defrost properly, leading to ice buildup and poor cooling.
Defrost Heater or Defrost Circuit Failure
E5
Display shows E5 and the wine cooler may shut down or fail to cool after running briefly.
Compressor Overload / High Temperature Protection Fault
E6
Display shows E6 and the wine cooler does not respond properly to temperature settings or may not cool.
Communication Error Between Display PCB and Main Control PCB
E7
Display shows E7 and the interior fan may not run, causing uneven temperatures and poor cooling.
Evaporator Fan Motor Fault
E8
Display shows E8 and the wine cooler may not cool or may cycle erratically.
Compressor Relay / Compressor Drive Fault
E9
Display shows E9 and the wine cooler may shut down or fail to maintain temperature, sometimes accompanied by beeping.
Door Switch / Door Ajar Sensor Fault
EE
Display shows EE or flashes all segments; controls may be unresponsive and cooling may stop.
General Control Board Error / EEPROM Fault
Symptom
Compressor runs almost constantly with very few off cycles.
Long Run Time / Inefficient Operation
Symptom
Compressor short cycles, turning on and off frequently within a few minutes.
Short Cycling / Control Instability
Symptom
Condensation or water droplets forming on the inside of the glass door.
Door Condensation / High Humidity Ingress
Symptom
Control panel buttons do not respond or respond intermittently.
Unresponsive Touch Panel / Keypad Failure
Symptom
Display shows dashes (--) or blank temperature instead of a numeric value, but no specific error code.
Sensor Disconnected / Out-of-Range Reading
Symptom
Dual-zone Haier wine cooler: one zone cools properly while the other zone is warm.
Single-Zone Failure in Dual-Zone System
Symptom
Frost or ice buildup on the back wall or around the evaporator inside the wine cooler.
Excessive Frost / Defrost System Issue
Symptom
Glass door appears foggy or has condensation between the glass panes.
Failed Door Glass Seal / Insulated Glass Fogging
Symptom
Interior light does not turn on when the door is opened.
Interior LED / Door Switch Failure
Symptom
Shelves are difficult to slide or do not sit level, risking bottle instability.
Shelf Rail / Support Misalignment
Symptom
Temperature display does not match an independent thermometer placed inside the wine cooler.
Inaccurate Temperature Sensing / Calibration Issue
Symptom
Water pooling at the bottom of the wine cooler or leaking onto the floor.
Drainage / Defrost Water Leak
Symptom
Wine cooler beeps continuously or intermittently even when the door appears closed.
False Door Ajar Alarm
Symptom
Wine cooler emits a high-pitched squealing or chirping noise from inside the cabinet.
Evaporator Fan Bearing Wear
Symptom
Wine cooler interior has a chemical or burning plastic smell when running.
Overheating Component / Electrical Odor
Symptom
Wine cooler interior has a musty or moldy odor.
Odor / Microbial Growth Inside Cabinet
Symptom
Wine cooler interior is too cold; bottles or labels may show signs of freezing near the back.
Overcooling / Temperature Overshoot
Symptom
Wine cooler interior temperature fluctuates widely; some areas are much warmer or colder than others.
Uneven Cooling / Poor Air Circulation
Symptom
Wine cooler makes a loud humming or buzzing noise while running.
Excessive Compressor or Fan Noise
Symptom
Wine cooler makes a rattling or clanking noise, especially when the compressor starts or stops.
Mechanical Rattle / Loose Component
Symptom
Wine cooler not cooling at all; interior stays at room temperature and compressor does not run.
No Cooling – Compressor Not Starting
Symptom
Wine cooler not cooling; compressor runs but there is no noticeable temperature drop inside.
No Cooling – Sealed System / Refrigerant Issue
Symptom
Wine cooler runs but does not get cold enough; interior temperature stays above setpoint.
Insufficient Cooling / Poor Refrigeration Performance
Symptom
Wine cooler trips the household circuit breaker or GFCI when it starts.
Electrical Short / Ground Fault
Symptom
Wine cooler vibrates excessively, causing bottles to rattle.
Excessive Vibration / Installation Issue
Symptom
Wine cooler will not power on; display is blank and no sounds are heard.
No Power / Dead Unit
