A household maintenance method involving the use of A4 paper has been identified as a way to monitor refrigerator health. The technique allows users to detect moisture, ice buildup, and potential seal failures.

By placing paper in the freezer or between the door gasket and the frame, homeowners can assess if the seal is compromised. If the paper slides out easily, it indicates the gasket may not be providing a tight seal, allowing warm air to enter. Such issues can lead to frost accumulation, which hinders airflow and forces the compressor to run longer, thereby increasing electricity consumption.
