Compressor under-voltage error — supply voltage too low

The most common cause of the 85E error on a Samsung refrigerator is household brownout / low line voltage (~50% of cases); start with: power-reset.

What Does Error Code 85E Mean on a Samsung Refrigerator?

Compressor under-voltage error — supply voltage too low.

The inverter control monitors the DC bus and incoming line voltage while driving the compressor. When it measures supply below the operating floor needed to run the motor safely, it posts 85E, halts the compressor, and retries once conditions stabilize. This distinguishes it from over-voltage or drive-current faults in the related 83E/86E family, which trace to the motor windings or inverter output rather than the incoming mains itself.

Models affected: Samsung refrigerators with a digital inverter compressor, including models such as RF28R7351SG, RF263BEAESR, RF23M8070SR, RS27T5200SR, and RF27T5201SR
What owners report: Owners commonly report 85E appearing during summer brownouts or when a microwave, space heater, or other heavy load shares the refrigerator's circuit. It often clears on its own once line voltage recovers, and many find the quick win is simply giving the fridge its own dedicated outlet after a power reset.

What Causes Error Code 85E?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Household brownout / low line voltage 50% of cases
  2. 2
    Overloaded or shared circuit 25% of cases
  3. 3
    Inverter board fault 20% of cases
  4. 4
    Loose power connection 5% of cases

How to Fix Samsung Refrigerator Error Code 85E

🔧 Easy DIY Est. time: 10–20 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Power-reset

    Unplug for 5 minutes and restore. 85E after a brownout clears for good once supply stabilizes.

  2. 2

    Check the circuit

    Make sure the refrigerator has its own outlet — space heaters or microwaves sharing the circuit cause voltage dips under load.

  3. 3

    Measure outlet voltage

    If comfortable, verify the outlet reads ~115–125V under load. Chronically low readings are an electrician problem, not a refrigerator problem.

How to Reset Error Code 85E

Unplug the refrigerator for 5 minutes and restore power. Track whether 85E coincides with heavy appliance use elsewhere in the house.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

If your outlet voltage is healthy and 85E keeps returning, the inverter board needs professional replacement — and chronic low household voltage deserves an electrician's visit either way.

Average professional repair cost for this issue: $200–$450

Frequently Asked Questions

Can I keep using my Samsung Refrigerator when error 85E appears? +
You often can for a cycle or two, but the compressor issue behind 85E will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes 85E on a Samsung Refrigerator? +
Across reported Samsung refrigerator repairs, the most frequent is household brownout / low line voltage (50% of cases), overloaded or shared circuit (25%), then inverter board fault (20%). Check them in that order before replacing any parts.
85E keeps coming back after a reset — what should I check next? +
A reset only clears the stored 85E fault; if it returns, the compressor problem is still present. Move on to the physical checks — power-reset, then check the circuit — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Samsung Refrigerator error 85E? +
A DIY repair typically runs $0–$0 in parts, versus $200–$450 for a professional service call, so handling it yourself saves around $200. Expect the work to take about 10–20 minutes.
Which Samsung Refrigerator models show error 85E? +
85E is documented on Samsung refrigerators with a digital inverter compressor, including models such as RF28R7351SG, RF263BEAESR, RF23M8070SR, RS27T5200SR, and RF27T5201SR. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
