Appliance showing a code?
Use the code as a starting point—not a final diagnosis. Record the exact code, model number and what the appliance was doing when it appeared.
Sub-Zero code & message help
Record the complete display message and model. Avoid repeatedly clearing a returning fault without identifying the cause.
Check the owner-care instructions for your exact model and whether the message returns after appropriate maintenance.
Verify actual compartment temperature and protect food if temperatures are rising.
Record the code plus whether ice production, water flow or both are affected.
Wolf code & symptom help
For cooking equipment, note the exact code, cooking mode, set temperature and whether the oven or burner produces any heat. Avoid opening panels or working around live voltage or gas.
