Quick answer
85E on a Samsung refrigerator means the incoming power supply voltage is too low. The fridge's inverter board cannot safely run the compressor at reduced voltage.
What 85E means
The inverter board that drives the compressor monitors the incoming mains voltage. When the voltage drops below the safe operating threshold (typically below 170V), the board raises 85E and stops the compressor to prevent damage. Low voltage causes the compressor to draw excessive current, which overheats the motor windings.
85E is common in areas with unstable power supply, during peak electricity demand, or when multiple high-power appliances share a circuit.
Bangladesh context: Voltage instability is common in many areas, especially during summer peak load. A voltage stabiliser is strongly recommended for Samsung refrigerators.
How to fix it
- Check the voltage at the outlet with a multimeter. It should be 200-240V (nominal 220V). If below 180V, the supply is the problem.
- Wait for voltage to stabilise. If the problem is temporary (peak hours), the fridge will restart automatically once voltage returns to normal.
- Do not use an extension cord. Long or thin extension cords cause voltage drop. Plug the fridge directly into a wall outlet.
- Check your circuit. If other high-power appliances (AC, water heater, iron) share the same circuit, they can cause voltage sags when they turn on. Ideally the fridge should have its own dedicated circuit.
- Install a voltage stabiliser. A stabiliser rated for your fridge's power consumption (usually 500-1000VA) automatically adjusts the voltage to safe levels.
What does the 85E code mean?
85E indicates the incoming mains voltage is below the safe operating threshold. The inverter board has stopped the compressor to prevent low-voltage damage.
Common causes
- Low mains voltage from the power grid (brownout)
- Overloaded household circuit (too many appliances)
- Long or thin extension cord causing voltage drop
- Faulty wiring or loose connection at the outlet
- Defective voltage stabiliser (if one is installed)

How to fix the 85E error
Check outlet voltage
Measure with a multimeter. Should be 200-240V.
Wait for stabilisation
If temporary brownout, the fridge will restart automatically.
Plug directly into wall outlet
Remove extension cords.
Dedicated circuit
Avoid sharing with high-power appliances like ACs or water heaters.
Install a voltage stabiliser
500-1000VA rated for your fridge. Essential in Bangladesh.
Safety first: If you suspect a wiring problem, have a qualified electrician inspect the circuit. Do not use a fridge on a circuit with loose or burned connections.
Part you may need: Voltage stabiliser (500-1000VA)
In Bangladesh, a good quality automatic voltage stabiliser (AVR) costs 2000-5000 BDT and prevents most voltage-related fridge errors.
Frequently asked questions
Can low voltage damage my fridge?
Yes — repeated low-voltage operation can burn out the compressor motor. The 85E protection prevents this, but fix the root cause.
85E only happens at certain times?
This confirms voltage fluctuation. Peak hours (evening) or when your AC turns on are common triggers. A stabiliser solves it.
Will 85E clear on its own?
Yes — once voltage returns to normal, the fridge restarts. But if voltage is chronically low, you need a stabiliser.
