Wine cooler does not power on at all; no lights, no display, no fan.

Safety: Always unplug the unit before opening any panels. Do not bypass fuses with wire or foil.

Steps:

• Verify external power: Test the outlet with another appliance. Check the circuit breaker or GFCI outlet and reset if tripped.
• Inspect power cord: Look for cuts, crushed sections, or burn marks. If damaged, replace the entire cord set; do not tape over defects.
• Access main control board: Remove the rear service panel. Locate the main control board where the power cord connects.
• Check internal fuse: Many Magic Chef boards have a small glass or ceramic fuse. Inspect for a broken filament or discoloration. Test with a multimeter for continuity.
• Replace fuse (if blown): Replace only with the same type and rating. If it blows again immediately, there is a deeper electrical fault that needs professional diagnosis.
• Replace main control board: If the fuse is good but the board shows no signs of life (no LEDs, no output), the board's power supply is likely failed. Replace the main control board.
