Refrigerator cycles on and off rapidly or randomly; lights flicker.

Safety first: Turn off the breaker and unplug the refrigerator before inspecting wiring. Use caution when later testing live circuits.

Steps:

• Check plug and outlet: Ensure the plug fits snugly in the outlet. Avoid using adapters or extension cords.
• Inspect cord: Look for damage or signs of overheating.
• Control board connectors: Access the main control and reseat all harness connectors firmly.

Corrective action: If power supply and connections are solid but symptoms persist, replace the main control board. If the outlet or house wiring is suspect, have an electrician inspect and repair.
