Low Temperature Alarm / Overcooling
Lo
Display shows Lo and the cabinet feels very cold; some models may flash the code.
Temperature Below Display Range
— —
Temperature display shows dashes (— —) instead of a numeric temperature.
Temperature Reading Out of Range or Sensor Disconnected
Symptom
Buttons on the control panel do not respond or respond intermittently.
Keypad / Touch Control Failure
Symptom
Compressor and fans run continuously without shutting off, even when set temperature is reached.
Continuous Run / Control Feedback Failure
Symptom
Compressor does not start; you hear a clicking sound every few minutes but no cooling.
Compressor Start Failure
Symptom
Condensation or moisture forming on the inside of the glass door.
Door Condensation / High Humidity Ingress
Symptom
Digital display is dim, flickering, or some segments are missing, but cooling still works.
Display Module Degradation
Symptom
Door does not close properly or pops open slightly after being shut.
Door Alignment and Gasket Seal Issue
Symptom
Dual-zone Whynter wine cooler: upper zone cools but lower zone is warm (or vice versa).
Single-Zone Cooling Failure in Dual-Zone System
Symptom
Excessive frost or ice buildup on the back wall or around the evaporator.
Frost Accumulation / Defrost System Issue
Symptom
High-pitched squealing or chirping noise from inside the cabinet when cooling.
Evaporator Fan Motor Bearing Wear
Symptom
Interior light does not turn on when the door is opened, but the cooler otherwise works.
Interior Light Circuit Failure
Symptom
Interior temperature fluctuates widely; some bottles are much warmer or colder than others.
Uneven Temperature Distribution / Airflow Problem
Symptom
Loud rattling or vibrating noise when the compressor runs; noise may change when you push on the cabinet.
Cabinet Vibration / Loose Components
Symptom
Strong musty or moldy odor inside the wine cooler.
Microbial Growth on Interior Surfaces and Drain System
Symptom
Unit cycles on and off very frequently (short cycling), with small temperature changes.
Short Cycling / Control Hysteresis Issue
Symptom
Unit is very warm on the sides or top, more than expected.
Cabinet Heat Dissipation / Condenser Loop Warming
Symptom
Unit shuts off completely and then restarts only after a long time, even though the cabinet is warm.
Thermal Overload / Overheating Protection
Symptom
Unit trips the household circuit breaker or GFCI when it starts.
Electrical Overload or Ground Fault
Symptom
Water pooling at the bottom of the wine cooler or leaking onto the floor.
Drainage System Blockage or Defrost Water Leak
Symptom
Wine cooler does not turn on at all; display is blank and no lights or sounds.
No Power / Dead Unit
Symptom
Wine cooler is running but makes a loud humming or buzzing noise from the rear.
Noisy Compressor or Condenser Fan
Symptom
Wine cooler runs but does not get cold enough; temperature stays above setpoint with no error code displayed.
