Wine cooler does not power on at all; display is blank and no interior light when door is opened.

Safety: Before opening the unit, unplug it. Do not attempt repairs if you are uncomfortable working with electrical components.

Steps to troubleshoot no power:

• Check outlet and breaker: Plug a lamp or other device into the same outlet to confirm it has power. Reset any tripped breakers or GFCI outlets.
• Inspect power cord: Examine the NewAir power cord for cuts, kinks, or burn marks. If damaged, the cord must be replaced; do not tape or splice it.
• Test another outlet: Move the cooler to a known-good outlet (without extension cords) to rule out outlet issues.
• Access control board fuse: Remove the rear or bottom panel to locate the main control board. Many boards include a small glass or cartridge fuse. With power disconnected, inspect the fuse; if it appears blown (broken filament or darkened glass), test with a multimeter and replace with the same rating if blown.
• Check board for damage: Look for burnt components or discoloration on the PCB. If present, the board is likely failed.
• Replace faulty parts: Replace a blown fuse only once. If it blows again, or if the board is visibly damaged, replace the NewAir main control board (PCB).

Warning: If replacing the fuse or board does not restore power, there may be a wiring fault or other hazard. In that case, contact a professional technician.
