Older refrigerator models may require defrosting every two months or more frequently if needed.
Using Aluminum Foil in the Freezer:
When too much frost accumulates in the freezer, it’s time for a defrost. Ideally, empty the freezer first to ensure a thorough defrosting. Then, line the walls of the freezer with aluminum foil. This creates a protective layer, ensuring that any excess ice sticks to the foil instead of the freezer walls.
