Coffee maker will not power on at all; no lights or display.

Safety first: Unplug the coffee maker before any inspection. Do not attempt repair if you are not comfortable working with mains voltage.

• Check outlet and breaker: Test the outlet with another appliance. Reset any tripped breakers or GFCI outlets.
• Inspect power cord: Look for cuts, frays, or burn marks. If damaged, the cord must be replaced.
• Internal fuse check (advanced): Remove the bottom cover and locate the inline thermal fuse near the heating element wiring. Test for continuity with a multimeter. If open, replace with the same temperature and current rating.
• Board replacement: If the fuse and cord are good but the unit remains dead, the main control PCB is likely faulty and should be replaced rather than attempting component-level repair.
