Step-by-Step DIY Fix Guide
- SAFETY: Unplug the refrigerator — the compressor cannot operate safely under 85E conditions and running it risks permanent damage.
- Do not unplug and replug repeatedly without addressing the voltage issue.
- Check other appliances on the same circuit — if they are dimmer than usual or running slowly, the circuit has a voltage problem.
- Call Samsung Support at 1-800-726-7864 to report 85E.
- Transfer perishable food to a cooler with ice while awaiting service or voltage correction.
If the code comes back
- Immediately on first appearance of 85E if it does not clear after a single power reset
What This Error Means
Error 85E on your Samsung refrigerator means: The compressor inverter has detected that the supply voltage is too low to safely operate the compressor. Unlike 85C which is a general low-voltage warning, 85E specifically means the compressor cannot start or run safely under the current voltage. The refrigerator's self-diagnostic system has flagged this condition and may have paused affected functions.
The most frequent cause is sustained brownout or low-voltage condition from the power company. Work through the causes and steps below before calling a technician.
Samsung's official guidance classifies 85E as a technician-only fault. A 60-second power reset is the only DIY step. If the code returns, contact Samsung Support at 1-800-726-7864.
Do not unplug and replug the refrigerator repeatedly when a compressor error is active. Each restart attempt subjects a faulted compressor to a high-current inrush that accelerates damage. Unplug once, leave unplugged, and wait for a technician to diagnose before attempting another restart.
Most Likely Cause by Symptom
The Samsung refrigerator may stop, pause, or refuse to complete the cycle normally.
Likely cause: Sustained brownout or low-voltage condition from the power company
Check first: SAFETY: Unplug the refrigerator — the compressor cannot operate safely under 85E conditions and running it risks permanent damage.
Common Causes
- Sustained brownout or low-voltage condition from the power company
- Refrigerator on a shared circuit with heavy appliances pulling voltage down
- Wiring fault in the home reducing voltage at the outlet
- Inverter board fault causing it to report low voltage even when supply is normal
What Not to Do
- Do not run the refrigerator with 85E active — sustained low voltage will damage the compressor inverter board
Model and Display Variation Notes
Model-family notes
- Samsung refrigerator display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Service option
Samsung service visit if the warning returns after the basic checks are complete.
Manual and model check
Check your exact model and manual before ordering any Samsung refrigerator parts.
Common parts
- Inverter control board if board is misreading voltage ($80–$200)
This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.
When Not to Keep Troubleshooting
Immediately on first appearance of 85E if it does not clear after a single power reset
How to Prevent It Recurring
- Have a licensed electrician verify the refrigerator outlet voltage annually if you live in an area with known power quality issues
Related Error Codes
85C
The refrigerator has detected that the supply voltage from the wall outlet is below its safe operating threshold. This is most commonly triggered by a brief power outage or brownout. The error can typically be cleared without a service call.
86E
The compressor inverter has detected that the supply voltage is too high — a power surge condition. The compressor has been disabled to prevent damage to the motor windings and control electronics.
83E
The refrigerator's inverter board has detected an abnormal current draw from the compressor. This indicates an electrical fault in the compressor or its control circuitry that puts the compressor at risk of damage.
