Ice maker will not power on, display is dark, unit appears completely dead.

Safety first: Disconnect the ice maker from the mains supply before removing any panels or touching internal components.

Step-by-step checks:

• Verify outlet power: Plug a lamp or another appliance into the same socket to confirm it has power. If not, reset the circuit breaker or replace the wall outlet as needed.
• Inspect power cord: Check the SMEG ice maker power cord for cuts, burns, or kinks. If damaged, replace the entire cord set; do not attempt to tape or splice it.
• Check power switch: Ensure the ON/OFF switch is firmly in the ON position. Remove the rear or side service panel (if accessible) and test the switch for continuity with a multimeter. Replace the switch if it does not show continuity when ON.
• Examine internal fuse: On many SMEG ice makers, the main PCB has a small glass or ceramic fuse. Remove the cover, locate the fuse, and test it with a multimeter. If blown, replace it with the exact same rating. If it blows again immediately, suspect a shorted component on the board.
• Inspect main PCB: Look for burnt spots, bulging capacitors, or corrosion on the control board. If visible damage is present or the unit still does not power on after fuse and switch checks, the main PCB will likely need replacement.

When to stop: If you are not comfortable testing live voltage or replacing the control board, contact a qualified SMEG service technician.
