Advertisements
dE
Display shows dE or a door icon; interior light may stay on and cooling may stop intermittently.
Door Open / Door Switch Fault
E1
Wine cooler runs but does not cool properly; temperature rises above setpoint and display may flash E1.
Cabinet Temperature Sensor (NTC) Failure
E2
Wine cooler shows E2 and may run continuously or not cool correctly; temperature reading is erratic.
Evaporator Temperature Sensor (NTC) Failure
E3
Display shows E3 and the temperature setpoint cannot be maintained; unit may short-cycle or run continuously.
Ambient Temperature Sensor (NTC) Failure
E4
Wine cooler shows E4 and may stop cooling or enter a protection mode; compressor may not start.
Defrost Sensor or Defrost Circuit Fault
E5
Display shows E5 and compressor may not run or may shut down quickly; unit may click but not cool.
Compressor Overload or Start Protection Fault
E6
Wine cooler displays E6 and the internal fan may not run; cooling is weak or uneven.
Evaporator Fan Motor Fault
E7
Dual-zone La Sommeliere wine cooler shows E7 and one zone does not regulate temperature correctly.
Upper/Lower Zone Temperature Sensor Fault
E8
Wine cooler displays E8 and the interior light or control panel may behave erratically.
Control Panel Communication or Keypad Fault
E9
Wine cooler shows E9 and may not respond to temperature changes; compressor may be locked off.
Main Control Board Fault
Er
Display shows generic "Er" or "Err" and the unit may not respond to button presses.
Generic Control Error / Firmware Fault
F1
Wine cooler shows F1 and may not cool; often associated with thermoelectric (Peltier) La Sommeliere models.
Peltier Cooling Module or Heat Sink Fan Fault
F2
Thermoelectric La Sommeliere wine cooler shows F2 and does not cool; fan may run but no cooling occurs.
Peltier Power Supply or Driver Fault
H1
Display shows H1 or flashes a high temperature alarm; internal temperature is much higher than setpoint.
High Temperature Alarm / Overtemperature Condition
L1
Display shows L1 or a low temperature alarm; interior may be colder than setpoint and bottles may be over-chilled.
Low Temperature Alarm / Thermostat Control Fault
—
Display shows dashes ("--") instead of a temperature reading; unit may or may not cool.
Temperature Reading Lost / Sensor Out of Range
Symptom
Buttons on the control panel do not respond or respond intermittently; temperature cannot be adjusted.
Keypad / Touch Control Failure
Symptom
Clicking noise from the rear of the wine cooler every few minutes; compressor attempts to start but stops.
Compressor Short Cycling / Overload Trip
Symptom
Compressor-based La Sommeliere wine cooler cycles on and off very frequently (short cycling).
Short Cycling / Control Instability
Symptom
Condensation or mold forming on interior walls and shelves.
High Internal Humidity
Symptom
Condensation or water droplets forming on the inside of the glass door.
Door Condensation / Insulation Issue
Symptom
Display is blank or very dim, but the interior light and cooling still work.
Display Backlight / Control Panel Failure
Symptom
Door does not close properly or pops open slightly after being shut.
Door Alignment / Hinge or Gasket Problem
Symptom
Dual-zone wine cooler has one zone cooling normally while the other zone is warm.
Single-Zone Cooling Failure in Dual-Zone System
Symptom
Excessive frost or ice buildup on the back wall or around the evaporator, reducing storage space and cooling efficiency.
Defrost System Failure or Air Ingress
Symptom
High-pitched squealing or grinding noise from inside the cabinet, often when cooling is active.
Evaporator Fan Bearing Failure
Symptom
Interior light does not turn on when door is opened; cooling and display work normally.
Interior LED Light Circuit Failure
Symptom
Shelves or bottle racks are unstable or fall when loaded with bottles.
Shelf Support / Rack Fitment Issue
Symptom
Temperature displayed on the control panel does not match an independent thermometer placed inside the cabinet.
Temperature Calibration / Sensor Drift
Symptom
Thermoelectric La Sommeliere wine cooler is very hot at the rear heat sink but interior is only slightly cool.
Inefficient Heat Dissipation in Thermoelectric System
Symptom
Unit vibrates or makes noise only when certain shelves are loaded.
Load-Induced Vibration
Symptom
Water pooling at the bottom of the cabinet or on the floor in front of the wine cooler.
Drainage Blockage / Condensate Leak
Symptom
Wine cooler emits a burning or electrical smell; may be accompanied by smoke or discoloration.
Electrical Overheating / Component Burnout
Symptom
Wine cooler emits a strong chemical or plastic smell, especially when new or after long storage.
Odor / Off-Gassing
Symptom
Wine cooler interior is too cold; bottles may be partially frozen even at a moderate setpoint.
Thermostat / Temperature Control Overshoot
Symptom
Wine cooler is completely dead; no lights, no display, no sound.
No Power / Power Supply Failure
Symptom
Wine cooler makes loud rattling or vibrating noises, especially when the compressor runs.
Excessive Vibration / Loose Components
Symptom
Wine cooler not cooling at all; compressor does not run, interior light and display work normally.
Compressor Not Starting
Symptom
Wine cooler runs continuously but does not get cold enough; compressor is warm and vibrating, condenser is only mildly warm.
Refrigerant Leak or Low Charge
