How to Fix / Troubleshooting
Safety first: Turn OFF the breaker before inspecting any electrical connections. Use extreme caution around live terminals.
House power check:
- Verify the range is on a dedicated 240V circuit (for electric models) with correct breaker size as per Samsung specifications.
- Have a qualified person measure voltage at the outlet or junction box; low or fluctuating voltage can trigger this error.
Range connections:
- With power OFF, remove the rear terminal block cover.
- Inspect the power cord or conduit connections for loose screws, discoloration, or melted insulation.
- Tighten any loose terminal screws and replace any burnt wiring or terminal block.
After checks: Restore power and test. If the error persists with correct supply voltage and good connections, the main PCB power supply section may be defective and should be replaced by a technician.
