Display shows E9; interior lights may work but cooling is off or erratic

Safety: Unplug the refrigerator before inspecting the power cord or internal components.

Steps:

• 1. Check the outlet: Plug another high-load appliance (like a kettle) into the same outlet to verify it delivers stable power. Avoid using extension leads.
• 2. Inspect the power cord: Look for cuts, kinks, or burn marks along the cord and at the plug. Replace the cord if damaged (this should be done by a qualified technician).
• 3. Internal power supply: Remove the control board cover and inspect for burnt components or discoloration around the power supply section. If present, the board likely needs replacement.
• 4. Reseat connectors: Ensure the main power connector to the board is fully seated and not loose.
• 5. Professional repair: If E9 persists with a known-good outlet and intact cord, the internal power supply on the control board is likely faulty. Replace the main control board via an authorized service provider.

Note: Do not attempt to modify or repair the power supply section yourself; incorrect repair can create fire and shock hazards.
