Possible Causes

Weak mains supply, Failing internal SMPS power supply on PCB, Dried-out electrolytic capacitors, Loose power cord connection at strain relief

How to Fix / Troubleshooting

Safety first: Disconnect from mains before opening the unit. Power supply components can store charge; avoid touching capacitors.

Steps:

  • 1. Test another outlet: Plug the Daewoo air fryer directly into a different wall socket known to be reliable. Avoid extension cords.
  • 2. Inspect power cord and plug: Look for damage, overheating, or loose pins. Replace the cord set if suspect.
  • 3. Internal inspection (advanced): Remove the rear or bottom cover to access the power supply section of the PCB. Look for bulging or leaking capacitors, burnt resistors, or darkened areas.
  • 4. Reseat connectors: Ensure the mains input connector and any low-voltage connectors from the SMPS to the logic section are firmly seated.

Note: Component-level repair of the SMPS (replacing capacitors, ICs) should only be attempted by experienced electronics technicians. Most users should replace the entire control PCB.
