Advertisements
CF
Wine cooler displays CF or a communication fault code and may not respond to control inputs.
Communication Failure Between UI and Main Control Board
DOOR
Display shows DOOR or a door-open icon and an alarm sounds even when the door appears closed.
Door Open Sensor / Reed Switch Fault
E1
Wine cooler displays E1 and stops cooling or runs continuously without reaching set temperature.
Cabinet Temperature Sensor (NTC) Failure
E10
Wine cooler displays E10 and the compressor runs continuously or not at all, with incorrect temperature readings.
Main Control PCB Failure
E2
Wine cooler displays E2 and may run the compressor and fan erratically or not at all.
Evaporator Temperature Sensor (NTC) Failure
E3
Wine cooler shows E3 and interior temperature fluctuates widely or unit shuts down intermittently.
Ambient / Room Temperature Sensor Failure
E4
Wine cooler displays E4 and may not defrost properly, leading to ice buildup on the back wall.
Defrost Sensor or Defrost Circuit Failure
E5
Wine cooler shows E5 and the compressor does not start or stops shortly after starting.
Compressor Start / Overload Protection Fault
E6
Wine cooler displays E6 and interior fan does not run or runs erratically, causing uneven temperatures.
Evaporator Fan Motor Fault
E7
Wine cooler shows E7 and the display or touch controls behave erratically or are unresponsive.
User Interface / Display Board Communication Fault
E8
Wine cooler displays E8 and interior light does not function correctly or remains on continuously.
LED Lighting Circuit Fault
E9
Wine cooler shows E9 and the unit may shut down or fail to maintain temperature, sometimes accompanied by a beeping alarm.
High Temperature Alarm / Overtemperature Fault
H1
Wine cooler displays H1 or a similar code indicating high humidity or condensation alarm inside the cabinet.
High Humidity / Condensation Fault
LO
Wine cooler display shows LO or a low temperature alarm, sometimes with beeping, and the interior may be colder than the set point.
Low Temperature / Overcooling Fault
Symptom
Burning smell or electrical odor coming from the wine cooler during operation.
Overheating Electrical Component
Symptom
Condensation or water droplets forming excessively on the inside of the glass door.
Door Seal or Ambient Humidity Issue
Symptom
Display is on but buttons or touch controls do not respond, preventing temperature adjustment.
Unresponsive User Interface
Symptom
Door does not close properly or pops open slightly after being shut.
Door Alignment / Hinge Issue
Symptom
Door gasket is torn, cracked, or not sealing, leading to temperature fluctuations and condensation.
Door Gasket Failure
Symptom
Dual-zone SMEG wine cooler: one zone cools correctly while the other zone is warm or not cooling.
Single Zone Cooling Failure in Dual-Zone System
Symptom
Exterior side walls of the wine cooler feel very hot during operation.
Condenser Heat Dissipation Issue
Symptom
Frost or ice buildup on the back interior wall or around the evaporator area.
Defrost System Inefficiency
Symptom
Glass door feels unusually hot to the touch around the edges.
Door Frame Heater Overheating or Poor Ventilation
Symptom
Interior light does not turn on when the door is opened, but the cooler otherwise works normally.
Interior Light Failure
Symptom
Interior light stays on even when the door is closed, causing heat and higher internal temperature.
Door Switch Stuck Closed
Symptom
Shelves difficult to slide or do not sit level, causing bottles to be unstable.
Shelf and Rail Misalignment
Symptom
Temperature display is inaccurate; actual bottle temperature is significantly different from the displayed value.
Temperature Sensing / Calibration Error
Symptom
Unpleasant musty or moldy odor inside the wine cooler.
Internal Odor / Microbial Growth
Symptom
Water pooling at the bottom of the wine cooler interior or leaking out the front.
Blocked Condensate Drain
Symptom
Wine cooler cycles on and off very frequently, with short run times.
Short Cycling
Symptom
Wine cooler interior fan is noisy, squealing, or grinding during operation.
Evaporator Fan Bearing Wear or Obstruction
Symptom
Wine cooler interior is too cold; bottles near the back may partially freeze even at normal set temperatures.
Thermostat / Temperature Control Miscalibration
Symptom
Wine cooler makes loud humming or buzzing noise from the rear, louder than normal operation.
Noisy Compressor or Condenser Fan
Symptom
Wine cooler makes loud knocking or rattling noises when the compressor starts or stops.
Compressor Mounting or Tubing Vibration
Symptom
Wine cooler not cooling at all; interior remains at room temperature, compressor not running, display appears normal.
Compressor Not Starting
Symptom
Wine cooler runs but does not get cold enough; temperature is higher than set point despite long run times.
Poor Cooling Performance
Symptom
Wine cooler vibrates excessively, causing bottles to rattle or hum.
Excessive Vibration
Symptom
Wine cooler will not power on at all; display is blank and no sounds are heard.
No Power / Power Supply Failure
