Samsung Refrigerator 85C Error Code

Low voltage notice (Family Hub). Here is what it means and how to clear it, easiest fix first.

85C

Easy DIY fix

On Family Hub models, 85C reports that the supply voltage dropped briefly, often during a short power outage. Samsung describes it as harmless.

85C is not the same as 85E, the compressor under-voltage code covered in the 83E entry.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung 85C

Clear the message
Press and hold OK on the notice for 3 seconds to dismiss it.
Check your supply if it keeps appearing
If the notice returns often, make sure the fridge is plugged straight into a wall outlet, not an extension cord, and consider having an electrician check for voltage dips.

When to call a technician

No service is needed for a one-off 85C. Contact Samsung if it appears frequently along with cooling problems.
