Samsung Refrigerator
Severity: CriticalWhat Does This Error Mean?
The 85 E error means your Samsung refrigerator has a compressor control problem. The inverter control circuit for the compressor has detected a fault. The fridge may stop cooling if this is not addressed.
Affected Models
- RF28R6201SR
- RF23M8070SR
- RS27T5200SR
- Samsung inverter compressor refrigerators
Common Causes
- Inverter control board (compressor driver board) has failed
- Compressor has an internal fault or short circuit
- Wiring harness between the inverter board and compressor is damaged
- Overheating of the compressor from dust buildup on condenser coils
- Power supply issue causing irregular voltage to the inverter board
How to Fix It
-
Unplug the refrigerator and wait 5 minutes.
This fully powers down the inverter board. Plug back in and see if the error clears.
-
Clean the condenser coils at the back or bottom of the fridge.
Dusty coils cause overheating. Use a vacuum or brush to clean them carefully.
-
Make sure there is 2–3 inches of clearance around all sides of the fridge.
Poor ventilation causes the compressor to overheat and trigger errors.
-
If the error persists, check if the fridge is actually cooling.
Feel inside both compartments. If they're warming, food safety is at risk — act fast.
-
Contact Samsung support or a certified technician immediately.
The inverter board and compressor require professional diagnosis and repair.
When to Call a Professional
Compressor and inverter board repairs are complex and require specialized tools. Do not attempt this yourself. Expect repair costs of $200–$600 depending on the specific fault. Contact Samsung support immediately — this error can cause total cooling loss.
