A level fridge is essential for proper operation—an uneven refrigerator can affect door sealing, leading to poor performance, increased power consumption, and even temperature inconsistencies. However, floors are often not as level as expected so that additional adjustments may be needed.

🔹 Check the floor first – Your fridge’s adjustable feet help, but extra levelling may be required if the floor itself is uneven.
🔹 Simple fixes – Small Masonite or MDF pieces can be placed under the feet to correct minor unevenness.
🔹 Best long-term solution – A compressed timber base (such as plywood or MDF) cut to fit the fridge space ensures stability across the entire surface.

Spending a little time during installation can prevent long-term issues with your fridge’s efficiency. For more details, visit How to Level Your Refrigerator.
