Temperature Reading Above Sensor Range
L1
Wine cooler displays L1 or a low temperature alarm; bottles may feel too cold or partially frozen.
Low Temperature Alarm Condition
Lo
Display shows Lo instead of a temperature; unit may be very cold or sensor may be disconnected.
Temperature Reading Below Sensor Range
Symptom
Buttons on the control panel do not respond or respond intermittently.
Faulty Touchpad or User Interface
Symptom
Condensation forming on the exterior glass door of the wine cooler.
High Humidity or Door Heater / Frame Heater Issue
Symptom
Display is dim, flickering, or some segments are missing, but cooling still works.
Display Module or UI Power Issue
Symptom
Excessive frost or ice buildup on the back wall or around the evaporator inside the wine cooler.
Defrost System Failure or Air Leak
Symptom
Interior light does not turn on when the door is opened, but the cooler otherwise works.
Lighting Circuit Failure
Symptom
Interior light stays on even when the door is closed, causing warming and glare.
Stuck Door Switch or Control Logic Fault
Symptom
Musty or moldy odor inside the wine cooler.
Microbial Growth on Interior Surfaces or Drain System
Symptom
Strong chemical or burning smell coming from the wine cooler during operation.
Overheating Electrical Component or Contaminant on Heater/Compressor
Symptom
Water pooling at the bottom of the wine cooler or leaking onto the floor.
Defrost Drain Clog or Condensate Management Failure
Symptom
Wine cooler cycles on and off frequently; compressor starts and stops in short intervals.
Short Cycling
Symptom
Wine cooler does not run at all; display is blank and no lights or fans operate.
No Power / Dead Unit
Symptom
Wine cooler door does not seal properly; condensation or frost appears around the door area.
Door Gasket Failure or Door Misalignment
Symptom
Wine cooler door is difficult to open or makes a popping sound when opened.
Cabinet Vacuum or Gasket Adhesion
Symptom
Wine cooler has power (lights on) but compressor and fans do not run; interior warms up.
Control Board Not Calling for Cooling
Symptom
Wine cooler interior feels too humid; labels peel and condensation appears on bottles.
High Humidity in Cabinet
Symptom
Wine cooler interior is too dry; corks appear to be drying out.
Low Humidity in Cabinet
Symptom
Wine cooler interior temperature fluctuates widely; some bottles are too warm while others are too cold.
Poor Air Circulation / Temperature Stratification
Symptom
Wine cooler is excessively noisy; rattling, buzzing, or vibrating sounds are heard during operation.
Vibration or Loose Component Noise
Symptom
Wine cooler makes a loud grinding or scraping noise from inside the cabinet when running.
Evaporator Fan Blade Obstruction or Motor Failure
Symptom
Wine cooler runs but does not cool; interior stays warm despite compressor noise.
Sealed System Refrigerant Loss or Compressor Inefficiency
Symptom
Wine cooler runs continuously and rarely shuts off, even when the set temperature is reached.
Continuous Run / Control or Sensor Fault
Symptom
Wine cooler trips the circuit breaker or blows a fuse when it starts.
Electrical Short or Overcurrent
