What the appliance detected
Detected condition
Samsung says 85C on Family Hub is triggered by low voltage detected on the power source and could be caused by a brief power outage.
What may contribute
Possible causes
- Low voltage was detected on the power source.
- A brief power outage may have occurred.
Start conservatively
Safe preliminary checks
Work in order and stop whenever a step is not supported by the documentation for your model.
Record the code and model
- Photograph or write down 85C and confirm the exact Family Hub model.
- Note whether a brief power outage or household power event happened recently.
Check for electrical warning signs
- Stop for sparking, burning odor, visible cord or outlet damage, repeated breaker trips, or water near electrical parts.
- If those signs are present, do not press buttons to continue use; contact qualified help.
Clear the message as Samsung describes
- If there are no electrical warning signs and the display is otherwise operating normally, Samsung says 85C can be cleared by pressing OK for three seconds.
- If the message returns repeatedly or cooling is affected, request Samsung support or service.
Actions not recommended
- Do not open outlets, panels, compressor areas, boards, or wiring connections.
- Do not test live voltage or treat 85C as proof of a failed power component.
- Do not repeatedly clear a recurring power message without addressing the power context.
When to stop and request service
- Request Samsung support or service if 85C returns repeatedly, the refrigerator is not cooling, or the Family Hub panel behaves abnormally.
- Use a licensed electrician for outlet, breaker, surge, or household-voltage concerns.
- Stop immediately for electrical warning signs or visible damage.
