After cleaning, dry the seals thoroughly to prevent any moisture from seeping into the appliance.
Proper alignment of the seals is also crucial for maintaining the fridge freezer's efficiency. Misaligned seals can cause the doors to not close properly, allowing cold air to escape and warm air to enter. To check the alignment, close the doors and examine the seals from all angles. If you notice any gaps or misalignments, adjust the seals as necessary to ensure a tight fit.
Regular maintenance of the seals and gaskets can help prevent a noisy fridge freezer and improve the appliance's overall efficiency. By inspecting, cleaning, and aligning the seals, you can ensure that your fridge freezer operates quietly and effectively, saving you energy and reducing wear and tear on the appliance.
