Is it safe to keep using it?
Depends on code severity. Low/Medium codes often allow continued use, High severity requires immediate stop.
Can error codes be reset?
Some codes clear after power cycle. Persistent codes indicate underlying issues needing repair.
When should I stop using it?
Stop immediately for water leak codes, burning smell, or any High severity error.

Common Symptom
DOR
Wine Zone Door Open Alert
Medium
A regular soft beep cycles from the control panel for the wine zone only. The refrigerator zone door alarm continues to function normally and is silent unless its own door is left open.
View
E1
Wine Zone Door Sensor Malfunction
Medium
On an SBS unit each compartment has its own door switch. E1 produces a constant wine zone alarm even when the wine door is firmly closed; the refrigerator door alarm system continues to work normally.
View
E2
Secondary Wine Zone Air Sensor Fault
Medium
A two-zone Vinidor unit shows two wine temperatures on the InfoLight display. With E2 active, one wine zone shows the correct value while the other shows dashes, a frozen reading, or alternates between E2 and a value.
View
E7
Wine Zone Defrost Heater Fault
Medium
The wine zone temperature creeps upward as ice accumulates on the wine zone evaporator. The refrigerator and freezer zones continue to operate at their set points because they have their own defrost circuits.
View
E8
Wine Zone Defrost Timer Fault
Medium
E8 produces the same downstream symptom as E7: ice slowly accumulates on the wine zone evaporator and progressively blocks airflow.
View
F1
Wine Zone Temperature Sensor Fault
High
On an SBS or Vinidor unit, the InfoLight display shows multiple zones at once. F1 typically appears in the wine zone field while the refrigerator/freezer/other zones continue to show valid readings — a clear indicator that the fault is wine-zone-isolated.
View
F8
Cooling System Fault — Affects Multiple Zones
High
Unlike F1 (which is zone-isolated), F8 typically warms the wine zone AND the refrigerator zone of an SBS unit because they share a compressor. Both displays drift upward at similar rates.
View
TEMP SWING
Wine Zone Temperature Instability
Medium
The wine zone target is set to a single value, but the actual reading swings across a wider range than the normal ±1°F tolerance. Other zones may continue to be stable.
