Safety first: Before opening any panels, unplug the unit. If you are not comfortable working with mains voltage, contact a professional.

Steps to diagnose a dead Brandt wine cooler:

• 1. Check outlet: Plug a lamp or other device into the same outlet to confirm power is available. Reset any tripped breakers or GFCI outlets.
• 2. Inspect power cord: Look for cuts, kinks, or burn marks. If damaged, the cord must be replaced by a qualified technician.
• 3. Access main control board: Remove the rear service panel to locate the main PCB. Look for an onboard fuse (glass or ceramic).
• 4. Test and replace fuse: With the unit unplugged, remove the fuse and test for continuity. If blown, replace with the exact same rating. If it blows again immediately, there is a short that must be diagnosed.
• 5. Visual inspection: Check the PCB for burnt components or obvious damage. A charred board usually requires full replacement.
• 6. Professional service: If the fuse is good and power is present at the board but the unit remains dead, the main control board is likely faulty and should be replaced by a technician.
