Low or high supply voltage, Faulty main PCB power supply section, Loose power cord or outlet, Internal short drawing excessive current
How to Fix / Troubleshooting
Safety: Turn off the circuit breaker before inspecting the power connection.
- Check outlet and voltage: Verify the freezer is plugged directly into a properly grounded outlet (no extension cords). Use a multimeter to confirm voltage is within the range specified on the rating label (typically 110–120V or 220–240V depending on region).
- Inspect power cord: Look for cuts, burns, or kinks in the Samsung power cord. Replace if damaged.
- Reset breaker: Ensure the circuit breaker is not tripping repeatedly. Frequent trips indicate a wiring or load issue that should be checked by an electrician.
- Internal inspection: With power disconnected, inspect the main PCB for burnt components. If damage is visible or 86E persists with good supply voltage, the PCB likely needs replacement by a professional.
