Refrigerator randomly shuts off and then restarts, or display flickers.

Safety First: Avoid using extension cords or power strips with the refrigerator.

Steps:

• Check power connection: Ensure the power plug is fully inserted into a dedicated wall outlet.
• Test outlet: Plug another appliance into the same outlet to verify stable power. If the outlet is suspect, have it inspected by an electrician.
• Inspect control board: Remove the rear control cover and check the main PCB for loose connectors or signs of overheating.
• Improve ventilation: Ensure the rear of the refrigerator is not tightly enclosed, which can overheat the control board.
• Replace PCB: If flickering and random shutdowns persist with a good power supply, replace the main control board.
