Refrigerator seal gone bad: Simple test reveals hidden threat to your food

Moisture accumulation inside a refrigerator and premature food spoilage often signal a breach in the door seal's integrity. Even microscopic gaps allow warm air to leak into the cabinet, which triggers condensation, puts excessive strain on the compressor, and destabilizes internal temperatures. Residents can identify these leaks independently before calling a service technician. Diagnosing Seal Integrity The most reliable method to evaluate how well the door closes is the paper test. By placing a sheet of A4 paper between the seal and the refrigerator body and closing the door, a user can determine if the seal is functional. If the seal is intact, the paper should be held firmly in place and offer significant resistance when someone attempts to pull it out. "If the paper falls out under its own weight or is removed without effort, it confirms a breach in the cooling contour," explains Ilya Kondratyev, a residential operations specialist. According to Kondratyev, such gaps allow warm air to enter, which encourages the growth of pathogens and fungi and forces the appliance to consume more electricity to compensate for heat loss.
