Ice forming on the inside of the fridge compartment, especially on the back wall.

Adjust settings and usage:

• Set the fridge temperature to around 4°C (medium setting).
• Avoid placing food directly against the rear wall where cold air enters.
• Do not overpack shelves; allow air to circulate.

Check door seal:

• Inspect and clean the gasket.
• Perform a paper test: close the door on a sheet of paper; if it pulls out easily, the seal may be weak and require adjustment or replacement.

Defrost: If heavy ice is present, unplug the fridge and allow it to defrost fully before restarting.
