Washer-dryer combo will not power on at all; no lights or display, completely dead.

Safety first: Ensure your hands are dry and the area is not wet when working with power. Unplug the unit before opening any panels.

• Check outlet and breaker: Plug a lamp or tester into the same outlet to confirm power. Reset any tripped breakers or replace blown fuses in the home panel.
• Inspect power cord: Examine the Danby combo's power cord for cuts, burns, or crushed sections. Replace if damaged.
• Test outlet polarity: Use an outlet tester to ensure correct wiring and grounding.
• Internal line filter: Remove the rear or top panel and locate the noise filter / line filter board where the cord enters. Check for burnt components or loose connections. Replace the filter if damaged.
• Main PCB: If power reaches the control board but there is no display or response, the board's low-voltage power supply may have failed. Board replacement is usually required and best done by a qualified technician.
