Samsung Refrigerator 85E — What It Means & How to Fix It

By Callum Griffin · Researched and verified against manufacturer and repair documentation · Reviewed September 2026

85E is Samsung's compressor under-voltage error — the supply to the compressor dipped too low, which Samsung says can follow a brown-out.

What this code means

Samsung lists 85E as the Compressor Under Voltage Error and notes that a brown-out may have occurred. It sits beside 83E (abnormal compressor current) and 86E (compressor over-voltage): the control has seen the compressor's supply fall below what it needs and may stop the compressor to protect it.

Samsung's support page lists 85E as "Compressor Under Voltage Error". It is not the same as 85C, which Samsung describes as a harmless low-voltage notice on Family Hub models — see the 85C guide for that one.

Most likely causes

CauseHow likelyDIY-fixable?
Brown-out or low supply voltage Common Yes — power reset, 60 sec
Failed inverter board Common No — technician job
Compressor not starting Occasional No — technician job
Loose wiring to compressor Occasional No — technician job
Main PCB fault Less common No — technician job

What you can try yourself

  1. Power reset 60 seconds.
  2. Restore and observe if compressor attempts to start.
  3. Do not open doors for 10 minutes while it retries.
  4. Note any other concurrent codes (83E/86E) to tell the tech.
  5. If 85E persists, schedule sealed-system diagnostics.

When to call a technician

Typical professional repair cost: Typically $250—$650 for inverter/compressor-related service, model dependent.

Frequently asked questions

Is 85E the same as 85C?

No. Samsung lists 85E as a compressor under-voltage error and 85C as a low-voltage notice on the Family Hub power source that can be cleared by holding OK for three seconds. They are separate codes.

Should I keep resetting 85E?

No — one power reset is the safe trial. Repeated resets can stress the compressor; let a tech test the inverter and compressor.
