Samsung Refrigerator 86E — What It Means & How to Fix It

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

86E is Samsung's compressor over-voltage error — the supply to the compressor went too high, which Samsung says can follow a power surge.

What this code means

Samsung lists 86E as the Compressor Over Voltage Error and notes that a power surge may have occurred. It sits beside 83E (abnormal compressor current) and 85E (compressor under-voltage): the control has seen too much voltage on the compressor supply and may shut the compressor down to protect it.

Samsung's support page lists 86E as "Compressor Over Voltage Error". If the code followed a storm or an outage, a single power reset is the first step; a code that returns needs service.

Most likely causes

CauseHow likelyDIY-fixable?
Power surge or high supply voltage Common Yes — power reset, 60 sec
Failed inverter Common No — technician job
Compressor failing to start Occasional No — technician job
Harness loose at inverter Occasional No — technician job
Main PCB Less common No — technician job

What you can try yourself

  1. Do a 60-second power reset.
  2. Listen at the back for a hum or click as compressor tries.
  3. Keep unit powered and doors closed to let it retry.
  4. Record whether 86E is alone or with 83E/85E.
  5. If it persists, book inverter/compressor testing.

When to call a technician

Typical professional repair cost: Inverter/compressor service for 86E generally $250—$650 including diagnostics.

Frequently asked questions

What causes 86E on a Samsung refrigerator?

Samsung describes it as a compressor over-voltage error and says a power surge may have occurred. Reset the power once; if 86E comes back, the compressor circuit needs a technician.

Is 86E dangerous?

It protects the compressor by shutting it down. One reset is safe; if it stays warm, move food and call service.
