Freezer does not start at all; display is blank and no lights are on.

Safety: Ensure your hands are dry when working with electrical outlets. Unplug the freezer before opening any covers.

• 1. Check outlet: Plug another device into the same outlet to confirm power is present.
• 2. Inspect plug and cord: Look for damage, burns, or loose connections. Replace the cord if damaged.
• 3. Check household breaker: Reset any tripped breaker or replace a blown fuse in your distribution board.
• 4. Access control board: Remove the control housing and inspect for an internal fuse. Test and replace with the same rating if blown, but investigate for underlying faults.
• 5. Board replacement: If the internal fuse is intact but there is no sign of life, the main control board's power supply may have failed and should be replaced with a Siemens-compatible PCB.

Note: If fuses blow repeatedly, consult an electrician or technician to check for short circuits.
