Samsung Error Code 85C
Low voltage warning
Common Causes
- 1Power fluctuation
- 2Outlet issue
Step-by-Step Troubleshooting
- 1
Use a multimeter to measure the outlet voltage — Samsung refrigerators require 110-120V AC. Below 100V triggers the 85C code
- 2
Check if the refrigerator is plugged into an extension cord or power strip — these can cause voltage drop under compressor startup load. Plug directly into a wall outlet
- 3
Test another appliance on the same outlet to confirm the outlet is delivering proper voltage
- 4
If voltage at the outlet is low, check the home breaker panel — the circuit may be overloaded or the breaker may be weak. A dedicated 15A or 20A circuit is recommended
Pro Diagnostic Tip
Sacramento homes built before 1970 commonly have under-gauge wiring that sags below 105V under load. If the 85C code appears during peak AC usage (summer afternoons), the issue is building electrical capacity, not the refrigerator.
You Might Also Notice
- •Display flickering or dimming
- •Compressor struggling to start
- •Other appliances on the same circuit running slow
