What does this code mean?

Low supply voltage was detected at the compressor.

Source scope: Compatibility with specific model numbers has not been established. Always check your exact appliance manual.

Code meaning compared with manufacturer material — exact model not independently verified

Documented model/series: Samsung US destek sayfasının kapsadığı modeller (tam model belirtilmiyor). Evidence: Samsung US: Refrigerator error codes; her modelde geçerli olduğu söylenmiyor. Codes can mean different things on other models. This does not establish a failed part.

What can you try?

  1. 01

    Identify the exact code and model

    Photograph the Samsung display showing 85E and the product model label. The cited manufacturer evidence covers: Samsung US destek sayfasının kapsadığı modeller (tam model belirtilmiyor). Do not assume other models use the same code meaning.

    What the result means: If your model differs, consult its specific manual before acting on the guidance.

  2. 02

    Check for recent power anomalies

    Samsung links this group to supply voltage or communications disturbances. Do not dismantle the electrical or compressor system.

    What the result means: Recurring electrical problems may require an electrician.

  3. 03

    Use the specified single 60-second reset only if safe

    For these codes Samsung instructs disconnecting power using the plug or circuit breaker for 60 seconds, then restoring it. Do not touch any hot, wet or damaged connection.

    What the result means: If the code returns, contact Samsung rather than repeating resets.

  4. 04

    Escalate if the code persists

    Give authorised support the exact code, model number and when it appeared. Do not open electrical control boards, valves, fan housings, compressor systems or refrigerant pipes.

    What the result means: A code description alone does not prove which component must be replaced.

Stop immediately for leaks, smoke, burning smell or electrical danger. For gas leaks, leave the area and call local emergency services.

How do you actually fix this?

Start with safe checks. Some codes have no safe home fix; in that case we explain what the professional repair actually involves.

Practical fixes you can try

  1. Check whether other appliances have power. If a socket is scorched, loose, sparking or smells burnt, do not touch it; call an electrician.
  2. Follow the model requirements for a correctly rated earthed outlet; have improper extension or multi-plug wiring checked by a qualified electrician.
  3. After a power interruption, wait until supply is stable and conditions are safe. Do not repeatedly reset the appliance.

If it persists, how is it actually repaired?

An electrician verifies supply and earthing. An appliance technician then tests the input protection, wiring and board per the service manual and repairs only a measured fault.

How do you know it is fixed? Power should remain stable under normal use without the same voltage warning.

Safety and warranty: Warranty terms depend on manufacturer, model and local law. Damage caused by unauthorised disassembly or improper repair may be excluded. Live electrical work, gas, refrigerant circuits and sealed cabinets require qualified professionals; this is not a DIY instruction for those tasks.

Evidence: The manufacturer link above supports the broad code meaning. The repair pathway is a general technical diagnostic explanation, not a confirmed failed-part diagnosis for every model.
